Product Usage Instructions
- Top Toolbar and Preset Browser
- Save- Use this to save patches. There are a couple of levels of hierarchy:
- Collection- This is the top level of organization, and contains entire sets of presets. The Lowdown Presets are the main included collection. We also include a User Presets Collection for storing your own presets, but you’re free to create your collections. To create a new collection, click in the Collection text field (where it says User Presets above) and
- Browsing Patches
- Patches can be browsed by clicking the field. To select a preset collection, click in the area that says or on the downward-facing arrow next to it. Clicking on the left-side categories narrows down which patches are displayed.
- will show presets from all collections and categories.
- displays recently used presets.
- Refresh- This is the circular arrow button to the right of the downward arrow; clicking this checks the Cherry Audio server for new or updated presets.
- Patch Selection List
- Pin- Clicking the push-pin icon locks the patch selection list open, allowing fast and easy browsing and auditioning of patches. Click the icon again to disable pin mode. When in pin mode, the up and down arrow keys can be used to select patches.
- Preset Step Back/Forward
- Horizontal arrows- These step to the previous or next preset. macOS [+left/right arrow key] or Windows [CTRL+left/right arrow key] will navigate through presets back and forth in the currently selected collection/category.
- Undo/Redo
- Circular arrows- These undo or redo the last action. It remembers many steps, so if you mucked something up, keep on clickin’…
- Settings
- This is where user preferences for user interface, audio interfaces, user account, and more are configured. See the Settings section for full information.
- Importing Presets with drag-and-drop
- Presets can be imported singly or en masse (as a single compressed ZIP file) simply by dragging and dropping from the desktop anywhere on the user interface.
- If a single .*preset file is dragged and dropped, the sound is immediately loaded and the standard Save Preset dialogue appears; this lets you save the sound to the instrument’s preset browser. Note that you don’t have to save the sound to the preset browser; if you just want to hear and play the sound, click the Cancel button in the Save Preset dialogue – the sound will still be loaded.
- Compressed zip files containing multiple sounds can also be dragged and dropped onto the UI. This works the same as with singlesounds, but instead of the Save Preset dialog, you’ll see the Import Preset Collection dialog. The presets will be added as a new collection and available in the categories for which they were tagged.
- Zoom Magnifying Glass
- Click to resize the Lowdown interface. Selecting 100% returns the user interface to its native size.
- MIDI Tab
- Opens the MIDI controllers tab for configuring internal and hardware MIDI controls. See the MIDI Controllers Setup and MIDI Tab section for full information.
- FAQ
- Q: Can I create my preset collections?
- A: Yes, you are free to create your preset collections. Simply click in the Collection text field and enter a new collection name.
- Q: How can I navigate through presets?
- A: You can navigate through presets by using the Patch Selection List and the Preset Step Back/Forward horizontal arrows. On macOS, you can also use the left/right arrow keys, and on Windows, you can use the CTRL+left/right arrow keys.
- Q: How do I import presets?
- A: You can import presets by dragging and dropping them from the desktop onto the user interface. For single presets, the sound is immediately loaded and you can choose to save it to the preset browser. For compressed zip files containing multiple presets, they will be added as a new collection.
Preset Browser
Top Toolbar and Preset Browser
- The purple strip at the top of the Lowdown interface is where you’ll load, save, and create sound presets. It also contains utility functions such as undo/redo, UI zoom and Focus controls, under-the-hood settings, and more. Let’s go over the:
- New- Opens a new blank patch preset. If an unsaved patch is currently open or you’ve modified an existing saved patch, a dialogue asks if you’d like to save the patch in its current state. This greatly reduces the possibility of losing an edited unsaved patch.
- Save- Use this to save patches. There are a couple of levels of hierarchy:
- Collection- This is the top level of organization, and contains entire “sets” of presets. The Lowdown Presets are the main included collection. We also include a User Presets Collection for storing your own presets, but you’re free to create your own collections. To create a new collections, click in the Collection text field (where it says User Presets above) and type a name. User-created sounds can be freely saved to any collection; we like to keep ‘em separated for organizational purposes.
- Categories- Within each Collection are a number of sound categories. As with collections, you’re free to create as many categories as you like. To create a category, click in the Category text field of the Save dialog window and type a new category name.
- Patch- A patch is an individual sound. To save a patch, simply type the name in the Name field and click Save.
- Keywords- You can add descriptive words such as “bass,” “bassy,” or “Gene-rush,” etc., to patches to make them appear when terms are typed in the Search field. Use commas to separate multiple keyword entries.
- Browsing Patches- Patches can be browsed by clicking the
- Collections > or on the downward-facing arrow next to it. Clicking on the left-side categories narrows down which patches are displayed.
- < All Presets> will show presets from all collections and categories.
- < Recent> displays recently used presets.
- Refresh- This is the circular arrow button to the right of the downward arrow; clicking this checks the Cherry Audio server for new or updated presets.
- Pin- Clicking the push-pin icon locks the patch selection list open, allowing fast and easy browsing and auditioning of patches. Click the icon again to disable pin mode. when in pin mode, the up and down arrow keys can be used to select patches.
- Preset Step Back/Forward horizontal arrows- These step to the previous or next preset. macOS [⌘+left/right arrow key] or Windows [CTRL+left/right arrow key] will navigate through presets back and forth in the currently selected collection/category.
- Undo/Redo circular arrows- These undo or redo the last action. It remembers many steps, so if you mucked something up, keep on clickin’…
- Settings- This is where user preferences for user interface, audio interfaces, user account, and more are configured. See the Settings section for full information.
Importing Presets with drag-and-drop
- Presets can be imported singly or en masse (as a single compressed ZIP file) simply by dragging and dropping from the desktop anywhere on the user interface.
- If a single .*preset file is dragged and dropped, the sound is immediately loaded and the standard Save Preset dialogue appears; this lets you save the sound to the instrument’s preset browser. Note that you don’t have to save the sound to the preset browser; if you just want to hear and play the sound, click the Cancel button in the Save Preset dialogue – the sound will still be loaded.
- Compressed zip files containing multiple sounds can also be dragged and dropped onto the UI. This works the same as with single sounds, but instead of the Save Preset dialogue, you’ll see the Import Preset Collection dialogue. The presets will be added as a new collection and available in the categories for which they were tagged.
- Zoom Magnifying Glass- Click to resize the Lowdown interface. Selecting 100% returns the user interface to its native size.
- MIDI Tab- Opens the MIDI controllers tab for configuring internal and hardware MIDI controls. See the MIDI Controllers Setup and MIDI Tab section for full information.
- (MIDI Panic) – Click to send an all-notes-off message in case of, “Why won’t this thing stop making noise?!?” stuck-note incidents.
- QWERTY Musical Typing Keyboard- Opens an onscreen keyboard allowing a standard QWERTY computer keyboard to be used for playing music notes. For more information, see the QWERTY Musical Typing Keyboard (MTK) section.
- Q Oversampling Quality – The Q button sets Lowdown’s internal oversampling rate; the higher the setting, the better audio fidelity will be, with the caveat that more computer processing power will be required.
- Internal processing can be set to 1x (the same rate as the current sample rate of the host DAW or in the Settings>Audio/MIDI window for the standalone version) or 2x, 3x, or 4x the current sample rate. The sample rate is downsampled at the instrument output stage to match the current host sample rate.
- For example, if the current DAW/instrument sample rate setting is 48 kHz, and oversampling is set to 2x, Lowdown’s internal processing runs at 96 kHz and is then reduced back to 48 kHz at the output stage.
- When oversampling is set to any multiple greater than 1x, the Q button glows yellow.
- Depending on some factors (audio system D/A converter quality, monitor speakers, the nature of the current Lowdown patch, etc.), you may not hear a big difference with higher settings.
- ? (Help) – Clicking this launches your web browser and opens this help document. (Confusing circular logic thing there, right?)
Focus Button
If you’re using a tiny laptop, the user interface can potentially be hard to see. With this in mind, the Focus button conveniently blows up Lowdown’s view to roughly twice its normal size within the current window size. Unlike the Zoom “magnifying glass” function, Focus doesn’t affect the current window size. By default, the patch panel section fills the current window, but the view can be scrolled vertically and horizontally with a mouse wheel, track pad, or Apple Mighty Mouse finger-scrolling. Or if you’re the last person on earth still using a single-button mouse, scroll bars will appear at the window edges when in Focus mode. (Guess what? YOU’VE GOT MAIL!) Using Focus mode couldn’t be easier – just click the Focus button the top menu bar, and the recessed panel controls are enlarged and centered. To return to standard view, click Reset. There’s also a superfast key shortcut – on Mac, hold the ⌘ [COMMAND] key and click the mouse; in Windows, hold the [OPTION] key and click the mouse. Focus can be reset with the same key shortcuts.
Cherry and Lowdown Synthesizer logos- Clicking either of these displays “about” information, and shows the version number and current registered user ID.
Preset List
Preset List Right-Click Functions
- Show File- This displays the selected preset in the Mac or Windows folder containing it. This is useful for backing up or sending a preset file to another user.
- Show In Original Category- Selects the preset within its category, i.e. the category will highlight in the left preset menu. The Show In Original Category command only displays if the preset was selected within the
, , or categories. - Favorites- Favorited presets will show in when the
category is selected. A star will display next to the preset name. Right-click on the preset and reselect Favorite to un-favorite it. - Delete- Deletes the selected preset.
- Restore Factory Preset- If one of the factory (i.e. not user) patches is edited and saved, selecting this command restores the patch to its unaltered “factory” setting. This menu will be grayed-out for user bank patches.
- Restore All Factory Presets From ‘Lowdown Presets’- If any patches from the “factory” Tortoise bank are edited and saved, selecting this command restores all of them to their unaltered “factory” setting.
- Restore All From Factory- If any patches from the “factory” banks are edited and saved, selecting this command restores all of them to their unaltered “factory” setting. At the time of writing, the Lowdown bank mentioned above is the only factory bank, so this function and the Restore All Factory Presets From ‘Lowdown Presets’ above have the same effect.
Preset Browser and Buttons
The original instrument included three factory presets plus a “variable” mode,
selected via large buttons above the foot pedals. Selecting the variable mode
enabled the synthesis Programmed Preset parameter controls, recessed behind a
hinged glass door. Clicking one of the remaining three presets chose a non-
editable factory preset, and disabled the controls behind the glass door,
except for Tune, Beat, and Glide speed. Lowdown includes the Variable live-
panel mode, the three “factory” button presets, and our extensive preset
browsing menu, including a bunch of presets and the ability to store unlimited
user presets.
Using The Front Panel Factory Preset Buttons
Clicking the Bull, Tuba, or Bass buttons on the front panel selects the factory preset.
The glass door appears and the Programmed Preset sliders and octave switch are disabled. However, the Tune, Beat, and Glide rate controls remain active. These can be adjusted by clicking on the glass window, which will disappear and allow access. However, the remaining controls will be darkened to indicate that they’re disabled. The large Loudness and Filter foot sliders are always active. Just to be extra, super-duper clear: clicking the Bull, Tuba, or Bass preset buttons disables the recessed panel parameter controls except for Tune, Beat, and Glide rate, just like the real instrument. Click the Variable button to bring all controls back to life.
Creating and Editing User Sounds
To create and edit your own sounds, click the Variable button at the left.
This makes the Programmed Preset controls live and allows full editing of
sound parameters.
Saving User Sound Presets
Sounds saved user the preset browser in the top purple menu strip save all
current parameters, including the status of the four preset buttons. The three
factory button presets can be saved, and the disabled Programmed Preset
parameter status will be saved as part of the patch. Generally speaking,
you’ll probably want to use the Variable mode when saving your own presets.
Editing the Factory Preset Button Sounds
As mentioned above, clicking the Bull, Tuba, or Bass preset buttons
disables the Programmed Preset parameter controls, so what if you’d like to
tweak the Bull, Tuba, or Bass presets? We’ve got you covered! The preset
browser includes a Factory category where you’ll find “variable” versions of
the button presets; all sound parameters can be edited and saved as new user
presets.
Recessed Panel Controls
Selecting the Variable button activates the sound editing controls. In this section, we’ll go over what each of them do.
Tune/Beat/Glide Controls
- Unlike the other recessed panel controls, the Tune, Beat, and Glide controls are active at all times regardless of the currently selected large Presets buttons.
- Tune- Sets master tuning up or down by a semitone. Center position (5) corresponds to A-440. We’re not sure why they chose 0-10, but hey, we’re all about authenticity.
- Beat- Detunes the two oscillators against each other. A setting of zero equals no detuning. As the knob setting is increased, oscillator A becomes sharper, and oscillator B becomes flatter.
- Glide- Glide delays the voltage change between pitches for a sliding effect. works in conjunction with the Glide slider in the panel controls. Lower values = faster glide times, higher values = slower glide times. The large Glide button above the pedals must be on for glide to work.
- A unique feature of the original instrument is the use of V/Hz scaling. Unlike most analog synthesizers, this ensures consistent oscillator detuning, i.e. “constant beating” across the note range. This in turn, reduces phase cancellation between the two oscillators and is one of the reasons for its chunky sound.
Programmed Preset Controls
- The Programmed Preset controls are only usable when the Presets/Variable button is selected. If one of the remaining three preset buttons is currently selected, the Programmed Preset controls are dimmed and cannot be moved.
- Octave- Selects low, medium, or high octave range.
- A-B Mix- Mixes the level of Lowdown’s two oscillators, with centre position representing an equal mix. For the most powerful bass sounds, we recommend having one oscillator louder than the other – this reduces phase cancellation between the two oscillators, ensuring a more consistent and powerful bass tone. Oscillator B Frequency- Detunes oscillator B by up to one octave upward.
- Loudness
Sets the amplitude curve when the Variable preset mode is selected. Also a kickass Japanese metal band from the 80s known for their jam, “Rock and Roll Crazy Night.”
- Attack- Sets the amount of time it takes for the amplitude to reach the current Sustain Level setting.
- Sustain Level- Sets the level of held notes.
- Decay- Sets the amount of time it takes for the amplitude to fall to zero when keys/pedals are released. The large Decay button above the pedals must be enabled for the Decay parameter to work.
Filter
- Sets the voltage-controlled filter cutoff, resonance, and envelope settings when Variable preset mode is selected. Also a 90s rock band known for their depressing jam, “Hey Man, Nice Shot.”
- Cut-off Frequency- The filter removes high harmonics as its cutoff frequency setting is decreased from max, resulting in a dulling of sound. The Cut-off Frequency slider sets the frequency where attenuation begins.
- The Cut-off slider works in conjunction with the Filter foot control -the foot control slider essentially adds to the current Cut-off slider setting. Both control positions are stored when user sounds are saved.
- Emphasis- More commonly referred to as “resonance,” this emphasizes sound energy at and around the current cutoff frequency by adding feedback from the filter’s output back to its input. Lowdown’s implementation is self-oscillating, just like the original for the funky analog synth “wah” you know and love.
- Contour Amount- Applies a CV from the filter envelope to cutoff frequency. This allows familiar auto filter sweeps. When raising the Contour Amount control, you’ll generally want to lower the Cut-off and/or Filter foot slider, as these work in conjunction with one another.
- Contour Attack- Sets the amount of time it takes for filter cutoff to reach the maximum.
- Contour Decay- Sets the amount of time it takes for filter cutoff to fall to a minimum following the attack phase.
Additional Front Panel Controls
Foot Sliders
Loudness foot slider- Sets the master output level. On the original
instrument, this was a large control intended to be foot operated. We’ve
replicated the look of the original, but we don’t recommend using your foot to
adjust it, just uh… slide it with a mouse trackpad. Filter foot slider- Sets
the filter cutoff frequency. Like the Loudness control above, this was a foot
control for live performance use. If Tortoise is currently set to Variable
mode, it operates in tandem with the Programmed Preset Cut-Off (their silly
hyphen, not ours) slider; that is, it simply adds voltage to the current cutoff
frequency setting.
Glide/Decay/Octave Panel Buttons
- Glide- Glide delays the voltage change between pitches for a sliding effect. The Glide button works in conjunction with the Glide slider in the panel controls. Lower values = faster glide times, higher values = slower glide times.
- Decay- The decay enables or disables what’s usually know as “release,” that is, the fadeout of notes after you let go of a key. It functions in Variable mode or when one of the button presets is selected. Note that even when Decay is disabled, a very short release segment is still audible. This replicates the behavior of the original Taurus pedals.
- Octave- Shifts the range of notes up by one octave when enabled. This works in Variable mode or when one of the button presets is selected. It works independently of the Lo/Med/Hi Octave switch when in Variable mode.
Foot Pedal Keyboard
- The onscreen foot pedals can be used to play Lowdown with a mouse or trackpad by clicking on notes, and the appropriate foot pedals will move when Lowdown is played via a USB/MIDI controller or DAW.
- Though Lowdown only shows a one-octave onscreen keyboard, it can be played in any range using a USB/MIDI controller or DAW. We wouldn’t cut you short!
Under-Pedal Floor Images
By now you’ve probably noticed some of the fabulous floor coverings beneath the pedals. Lowdown includes 14 floor options.
To select a different floor image, click the Settings gear in the top purple menu strip.
Click the Interface tab at the top, then click Theme to select a floor option.
MIDI Controllers Setup and The MIDI Tab
- Assigning internal and external hardware controls adds a whole new dimension of control and musicality to patches, and it’s really easy to do.
- The MIDI Tab is where all controller assignments can be viewed and tweaked. First we’ll show how to assign an external hardware controller to a
- Lowdown control, then we’ll go over all parameters in the MIDI Tab.
Basic External Hardware Control Assignment
- This is the quick, “I just want to assign a hardware control right now!,” section.
- We recommend reading this whole section to best take advantage of Lowdown’s swell MIDI control assignments.
- In this example, we’ll assign a hardware knob/slider control to the large Filter foot slider.
- Begin by right-clicking on the Filter foot slider and selecting MIDI Learn.
- A transparent blue overlay appears over the foot slider indicating that it’s in learn mode. Now move the desired hardware control device. The blue overlay disappears and the hardware control will move the onscreen slider. If you get cold feet (or accidentally put the wrong control into learn mode), learn mode can be aborted by right-clicking and selecting Stop Learning.
- This is the basic procedure for assigning hardware controllers to almost any Lowdown control.
- When in MIDI learn mode, any previously assigned controller numbers will show in squares. These indicate the MIDI continuous controller number of the assigned hardware control (these are also displayed in the MIDI library tab at left).
- Once a MIDI controller has been assigned, in addition to real-time control of a Lowdown parameter, you’ll also be able to record and play back controller data from a DAW.
The MIDI Tab
- This is command central for all MIDI controller assignments. Here you’ll be able to see information about all currently assigned controllers and adjust control ranges.
- To view or hide the MIDI Tab, click the MIDI button in the top toolbar.
- MIDI Learn button- This is almost exactly the same as enabling MIDI learn mode by right-clicking a control. Click the MIDI Learn button to enter learn mode (all controls turn purple). Unlike right-clicking on specific knobs, where Lowdown automatically exits controller assignment mode, clicking the MIDI.
- Learn knob “stays on” to enable assignment of multiple hardware controls. This is handy for quickly assigning a bunch of sliders or the buttons of a grid-style controller.
- To assign multiple controls, click MIDI Learn, click an on-screen control, move the desired hardware knob or slider, continue clicking and assigning on-screen controllers until all desired controls are assigned, then click Stop
- Learning to exit learn mode. (And remember, when we stop learning, we stop growing, and… oh forget it.)
- Remember that a single hardware knob/slider/button isn’t limited to controlling just one parameter – a single hardware controller can simultaneously operate as many controls as you’d like.
- New Mapping Type- This popup menu selects whether newly assigned MIDI mappings will be global (affects all sounds and doesn’t change when different presets are selected) or saved with individual presets.
MIDI Tab Columns
- Name- Displays the name of the parameter being controlled.
- Type- There are five possible types of controller automation in Lowdown:
- Note- Notes played on a MIDI keyboard controller, expressed as C-1 to G9
- CC (MIDI Continuous Controller)- The standard 128 MIDI controller numbers as defined in the MIDI spec. More specifically, these are the controllers transmitted by hardware knob and slider controls. MIDI CC’s can be used to control parameters in real-time or recorded and played back within DAW software.
- MMC (MIDI Machine Control)- The MIDI control protocol for tape machine-style transport controls. Back in the dark ages, this was used to control wonky old Tascam and Fostex reel-to-reel monsters, but it’s useful if your MIDI controller has tape-style transport control buttons.
- Pressure- Most modern keyboard controllers transmit controller data when keys are pressed and released as they’re held down. The vast majority of keyboard controllers with aftertouch transmit “mono” aftertouch only; in other words, aftertouch data is the sum of all keys to one single data stream, but that shouldn’t present any problems, as Lowdown is a strictly monophonic (one-note-at-a-time) instrument.
- Key- This allows keys of the computer QWERTY keyboard to at as button controls for Lowdown’s onscreen controls.
- Value- Displays the specific automation controller. In the case of a Note this would show a MIDI note number (C-1 to G9, for a MIDI CC, this would be the MIDI CC controller number, etc. Clicking on the value opens a pop-up menu where all values are displayed and can be selected.
- Preset- This slider works in conjunction with the New Mapping Type popup control. In the left position (gray background), the MIDI mapping is global (affects all sounds and doesn’t change when different presets are selected), in the right position (lavender background), the MIDI mapping is saved with, and only affects the current sound preset. The Preset switch is super nifty because it means that MIDI mappings can easily be changed to global or per-preset status at any time. (A lot of folks have asked us for this feature.)
- Min- Sets a limit on the lowest value any automation control can set a mapped controller to. This recalibrates the range of the automation controller to the remaining parameter range.
- Max- Sets a limit on the highest value any automation control can set a mapped controller to. This recalibrates the range of the automation controller to the remaining parameter range.
- Super Tricky Min-Max Tricks- Not only can parameter ranges be limited via the Min and Max knobs, but mapped control destinations can also be completely inverted by setting the Min knob all the way up and the Max knob all the way down (or anywhere in between). Limiting and inverting parameter ranges with the Min/Max controls is particularly useful when multiplexing a single hardware control to operate multiple parameters. Along with the Curve control, the customization possibilities are super flexible.
- Curve- These allow the customization of how incoming MIDI CC controls affect the movement of Lowdown’s onscreen controls, ranging from exponential to linear to logarithmic curves.
MIDI Tab Column Configuration Right-Click Menu
Right-clicking anywhere in the top row (Name, Type, Value, etc.) displays the
column configuration menu. Checking/unchecking these allows hiding and display
of each column. This has no effect on assignments.
MIDI Tab Parameters Right-Click
- Right-clicking on an assigned parameter opens the menu above.
- MIDI Learn- This is used to change the controller assigned to a particular parameter.
- Unlearn- Deletes the selected automation parameter.
- Unlearn All- Deletes all controller assignments for the patch. Lowdown will display a warning dialog prior to deletion in order to thwart potential unlearn-related disasters.
- If you don’t have a MIDI keyboard attached to your computer, the standard QWERTY computer keyboard can be used to play notes – we’re pretty sure you’ve got one of those! We’ll refer to this as the “MTK.” Following is a list of MTK keyboard modifiers and functions:
- Opening and Closing the MTK – click the circular keyboard icon in the top toolbar. To close the MTK, click the keyboard icon in the top toolbar, or click the X in the top right corner.
- Play Notes- To trigger notes, simply press the corresponding computer keyboard key or mouse-click the onscreen keys.
- Adjust the Currently Visible MTK Range- Slide the purple scroll bar horizontally to adjust the currently visible keyboard range.
- Adjust Overall Visible Keyboard Range- Clicking and dragging the right edge of the MTL window allows the overall size of the window to be adjusted. This lets you view more or less of the onscreen keyboard. Note that the MTK window’s borders cannot exceed the overall outside dimensions of the Lowdown window.
- Shift Range Up/Down Octave- Click the OCT- and OCT+ buttons at the top left and right of the onscreen MTK. The current range is displayed above the keyboard.
- Shift Range Up/Down Semitone- Click the STEP- and STEP+ buttons at the bottom left and right of the onscreen MTK. The current range is displayed above the keyboard.
- Hide/View Controllers- Clicking CONTROL at the far left hides and displays velocity, bender, mod, and sustain control parameters. Hiding the control view makes more space available for the keyboard.
- Pitch Bend- To pitch a note or note, press the + or – computer keyboard keys while playing a note. Notes will bend up to an octave. Notes can also be pitch-bent by clicking the mouse in the Bend area.
- Mod Wheel- To add mod wheel modulation, press the number keys from 0-9 (above the character keys) while playing a note. The modulation amount will vary from none (0) to full modulation (9). Note that modulation will “stick” at the selected number; to disable modulation, click the 0 key. The mod can also be engaged by clicking the mouse in the mod bar area.
- Sustain- The Sustain button mimics the functionality of a standard sustain pedal. Click the [TAB] key to engage sustain, or [SHIFT]+[TAB] to lock it. The Sustain button can also be engaged by mouse-clicking it.
- Reset- Initializes all MTK parameters including keyboard range and control parameters.
Settings
Clicking the settings gear opens a window with multiple tabs for configuring various “under-the-hood” settings. These are mostly set-and-forget kind of parameters; everything you’ll usually use is right on the panel.
General
- Add Undo For Control Changes With the Mouse- Enabling this allows undo of knob/slider/button adjustments. You’ll want this on if you want the ability to undo all aspects of patch editing and programming.
- Create A Log File For Usage- This creates a text doc of all of Lowdown’s internal and routines during use. It is mainly intended for our tech staff should you experience any issues. Clicking Show Log Folder opens the folder containing Lowdown log file docs.
- Load Last Preset On Startup (Standalone Only)- Automatically loads the last preset used when Lowdown standalone version is started.
- Preset Folder- Displays the current location of Lowdown’s sound presets. This can be changed by clicking and typing in the field.
- Browse… – Displays the current location of preset folder in the file manager.
- Set Default- Sets the current displayed Preset Folder path as the default location
- Clear Cache Files- Deletes all log files, temporary sounds, and the image cache.
Interface
Allows customization of Lowdown’s user interface settings.
- Reset To Default Window Size- Resets the Lowdown workspace to default size. Use this to reset the window size if the window somehow becomes too large for your display and can’t be resized.
- Theme- Allows selection of 14 nifty floor surfaces beneath the pedals.
- Tooltip Delay- Tooltips are those informative bits of text that pop up when hovering over a control (go ahead and try it, we’ll wait…). The Tooltip Delay setting defines how long you must hover before the tooltip pops up.
- Knob Movement- Defines which how mouse movements related to turning onscreen knobs. It defaults to Vertical Drag, but can be changed to Horizontal Drag, or Rotary Drag if you’re one those folks that cut their teeth on the Steinberg Model E VST back in 2000.
- On Control Double-Click- Defines what happens when the mouse is double-clicked on a control. If Edit Value is selected, an exact number can be entered by typing the number and hitting [ENTER] or [RETURN]. If Sets Default Value is selected, double-clicking a control resets it to its default value.
- Mouse Wheel Adjusts Control Value- Enabling this lets you adjust knob, slider, and switch values by moving the mouse wheel. This works great with a standard mouse wheel, but you’ll want to disable it if you’re using an Apple Magic Mouse (which will move the control AND scroll the window).
- Show Control Tooltips When Adjusting Controls With Mouse- Displays parameter tooltips/values when the mouse is hovered over a control or as a control is moved with mouse clicked.
- Show Tooltips When Automating Controls- Displays parameter tooltips/values next to controls any time a control is changed, i.e. if a control is moved via an assigned MIDI controller or a Perform panel knob, etc.
- MIDI Program Changes Should Change Current Preset- Allows MIDI program change messages to change Lowdown patches.
- Ask To Save Modified Presets- This opens a dialogue window asking if you’d like to save changes if a patch has been edited and a new patch is selected. If you’re the type that likes to click through presets and tweak a control here and there, it can be annoying to have a window pop-up asking if you’d like to save every time you switch presets – if you’re that person, keep this off.
- Remember MIDI Mappings For New Plug-in Instances- When enabled, Lowdown remembers all MIDI Tab controller settings.
Account
Settings for your personal login information and account.
- Email- Displays the email address of the current login.
- Update Login Info- No, this isn’t a place for news and tour dates for yacht rock superstar, Kenny Loggins. Clicking this opens the same email and password login screen you’ll see when initially launching Lowdown.
- View Account Settings- This opens your account page on the Cherry Audio Store website containing information about modules purchased and more.
Software Update
We often fix bugs and make improvements; below are options defining how Lowdown handles updates.
- Check For Update- Click this to see if an updated version of Lowdown is available. Status-
- Automatically Install Updates- Updates are automatically downloaded and installed.
- Ask Before Installing Updates- By default, Lowdown automatically downloads new versions of modules when available. Checking this box defeats automatic updates and will ask if you’d like to install updates when they become available. We’ll never make changes that can potentially “break” existing patches but we recommend enabling Ask Before Installing Updates if you’re using Lowdown for live performances or other “mission-critical” situations.
- Never Install Updates- Lowdown never automatically installs updates.
- Show Updates On Toolbar- Checking this will display an icon in the toolbar next to the logo letting you know there’s an update available.
- Show Notifications From Cherry Audio- We occasionally will fire off in-app advertisements; disabling this checkbox will hide them. We hate repetitive, annoying ads as much as you do, so we won’t use this feature too often. When we do, it’ll be for something super cool (like a killer sale), so we recommend leaving it on.
Audio/MIDI
Not to be confused with audiomidi.com, where I used to work (talk about a not- fun job), these are settings for audio and MIDI hardware input and output. This tab is only visible in the standalone version of Lowdown.
- Output- Use this drop-down menu to choose a physical audio output source. This defaults to Built-In Line Output, i.e. your computer’s onboard system audio, but you’ll get better fidelity with an external professional audio interface. The biggest audible difference is usually reduced background noise or hum. The Test button will produce a brief sine wave when clicked; this will help with troubleshooting, aka, “WHY THE HECK ISN’T THIS MAKING ANY NOISE?!?”
- Sample Rate- This sets Lowdown’s global sample rate. Lower sample rates offer better performance, but if you have a fast computer, high sample rates may offer slightly improved fidelity.
- Audio Buffer Size- As with any digital audio app, this defines performance vs. note latency, and will largely depend upon computer CPU speed. A professional external audio interface will almost always exhibit better performance than “built-in” system audio. Lower settings will result in less latency (in the form of faster response to notes played), but will increase the chances of audio gapping or crackling noise.
- Active MIDI Inputs- Enable MIDI input sources, i.e. MIDI/USB keyboards, pad controls, MIDI knob/fader control surfaces, etc. Checkboxes to enable one or more devices. If a MIDI/USB controller isn’t working, make sure the appropriate box is checked here. (We put this this piece of info way in the back of the manual, to make it extra challenging to find out when things aren’t working.)

Lowdown recreates the super-fat, room-rattling lowdown sounds of the most legendary dual-oscillator bass pedal synth ever made. From the dual “constant- beat” oscillators to the girthy ladder filter, DSP wizard Mark Barton (MRB) has modeled every aspect of the original with exceptional accuracy. Outside of a handful of organ-oriented instruments, the original instrument was the first dedicated foot-controlled bass synthesizer, and with its enormously girthy tone, unquestionably the best sounding. It was used by some of the top acts of 70s and 80s, including Rush, Yes, Genesis, U2, and The Police (check out the intro of “Don’t Stand So Close To Me” or Phil Collins’ “I Don’t Care Anymore.”)
- The original design used a Hz/V oscillator scaling (as opposed to the more conventional volts/oct oscillator scaling) that allows oscillator detuning amount to remain constant across the keyboard by minimizing the phase cancellation that can happen when two oscillators play simultaneously.
- Along with a couple of other engineering tricks, this contributes to its beefy sound.
- To create Cherry Audio Lowdown, DSP and synthesis legend Mark Barton carefully analyzed the original’s synthesis circuits and precisely recreated them for a massive virtual bass experience like no other.
- We’re simply thrilled with the outcome of this fun and easy-to-use earth-moving bass experience and we hope you love it as much as we do!
Manual Layout
- This manual will detail each section of Lowdown; the order of the chapters follows the signal flow (as opposed to the physical layout of the front panel).
Technical Assistance
