STUTTER IN DEPTH
The Ottobit Jr.’s Stutter effect records and plays back audio to create the stuck buffer sound popularized by the character Max Headroom in the 80s. The Stutter control knob sets the stutter length and how many times the stutter repeats. The knob is broken up into three-speed ranges: full speed, double speed, and half speed, and each range has 7 different selections. Adding to that, the minimum position of the stutter knob turns the stutter off, and turning the knob to its maximum sets the stutter to random, giving you 23 positions in total. Here they are:
Stutter knob sections
- Stutter Off
- Full Speed, Stutter Once
- Full Speed, Stutter Twice
- Full Speed, Stutter Three Times
- Full Speed, Stutter Four Times
- Full Speed, Stutter Six Times
- Full Speed, Stutter Eight Times
- Full Speed, Stutter Sixteen Times
- Double Speed, Stutter Once
- Double Speed, Stutter Twice
- Double Speed, Stutter Three Times
- Double Speed, Stutter Four Times
- Double Speed, Stutter Six Times
- Double Speed, Stutter Eight Times
- Double Speed, Stutter Sixteen Times
- Half Speed, Stutter Once
- Half Speed, Stutter Twice
- Half Speed, Stutter Three Times
- Half Speed, Stutter Four Times
- Half Speed, Stutter Six Times
- Half Speed, Stutter Eight Times
- Half Speed, Stutter Sixteen Times
- Random (combination of all of the above, plus the reverse of all the above)
STUTTER HOLD IN-DEPTH
Hold Tap Tempo, hold an external tap switch, or send the Stutter Hold MIDI CC to freeze the audio that is being stuttered. The Stutter Hold works by freezing whatever the stutter is playing. If the stutter is playing back some snippet of audio, then holding tap will immediately hold that snippet indefinitely until you let go. You can also enter a stutter hold before a stutter has trapped any audio. Without playing anything, hold tap to tell the Ottobit Jr. that you want the stutter to be held, and then we you play something it will stutter that note or chord until you let go. Both ways work, and the response time should feel immediate. If you are having trouble getting the stutter to trigger, try playing dry guitar into the Ottobit Jr. Then, once you get the results you’re after, try adding back your external effects. The pick attack detection can work on most signals, but if your signal is extremely noisy, then it may have a hard time discerning pick attacks from the noise (like if you had an extremely cranked fuzz pedal at the input).
SEQUENCER IN DEPTH
The Ottobit Jr, features a 6-step sequencer with three different control types: Pitch Sequence, Filter Sequence, and Sample Rate Sequence. To set the value of each of the six steps, simply hold the Alt switch and move the knob corresponding to the step you want to edit. For all sequencer types, while holding Alt to edit a step, when the knob is at minimum that step is skipped, and when the knob is at the maximum that step is muted. To tune just one step, hold down the alt button, set 5 of the knobs to a minimum, and then just use one of the knobs to tune a single step. This is a good way to go if you feel a little lost. And this is usually how to start dialing in a sequence. Set all the knobs to Skip and then start adding the steps into the sequence one by one.
Pitch Sequence
When set to sequence pitch, each step gives you the choice of every
semitone between and octave below and an octave above the guitar pitch, with
the middle of the knob equal to no shifting (just dry guitar). And as with
every mode, when the knob is at minimum, that step is set to Skip; and when
the knob is set to maximum, that step is set to Mute. To sum up, between Dry,
Skip, Mute, and 24 different semitones, you have 27 different choices for the
pitch sequence on each step.
Filter Sequence
The sequencer controls the filter as a modifier, meaning each individual step
of the sequencer modifies whatever the main front panel Filter knob is set to.
This way, the sequence is always tracking what the front panel Filter knob is
doing and the Filter knob always sets the overall maximum cutoff frequency. It
is probably easiest to think of it in terms of percent. When adjusting the
steps, if you turn a 2nd layer knob to noon that step will change the filter
frequency to 50 percent of what you had set on the front panel. So if you set
the main Filter control to a cutoff of 1000Hz, then when that step of the
sequence comes around you would hear a filter cutoff of 500Hz.
Sample Rate Sequence
The Sequencer also works as a “modifier” or “second source” when controlling
the Sample Rate. When the sequencer is set to Sample Rate, it is modifying
whatever the front panel Sample Rate knob is set to just like it does when it
is set to control the Filter cutoff. And as with every mode, when the knob is
at minimum, that step is set to Skip; and when the knob is set to maximum,
that step is set to Mute.
EXPRESSION JACK MODES IN DEPTH
Expression Pedal
The expression pedal works by morphing between two complete settings of all of
the knob values (even the second layer knob values). This gives you two
complete and distinct presets in one that you can then use the expression
pedal to morph between. Put the expression pedal to the “toe up position” and
set the knobs (including the 2nd layer ones) any way you wish, and then put
the expression pedal to the “toe down position” and set the knobs to create
your second sound. Now sweeping the expression pedal from heel to toe will
smoothly morph between those two sets of settings. You can also manipulate the
expression pedal using MIDI CC #04.
Tap Switch
For the Ottobit Jr., the external switch controls Tap Tempo and have all of
the same functionality as the tap button on the main pedal, this includes
Stutter Hold. As with the main tap switch, if you hold the externally
connected tap switch it will cause the stutter to hold the current or the next
valid stutter buffer.
4 Button Preset Switch
This mode gives you access to an instant enabling of presets 1 through 4 when
connected with a proprietary Meris 4 button switch.
MIDI
The Ottobit Jr. features both MIDI In and Out via the EXP jack and has a rich
and deep MIDI implementation. All the knobs, alt functions, expression pedals,
and switches are available via MIDI CCs. You can receive program change
messages (MIDI PCs), and sync to MIDI Beat Clock (Ottobit Jr.), you also have
the ability to send and receive presets. Be sure to set your desired MIDI
channel in Global Settings Configuration Mode. If you have multiple devices
connected to MIDI in a chain, you will probably want each device to set to
listen to and send on its own channel.
KNOB BEHAVIOR IN DEPTH
Depending on the EXP Jack modes you have chosen, the Ottobit Jr. will scan the top layer knobs and update the knobs on power-up. If your Ottobit Jr. is set to either “Expression Pedal” or “Tap Switch” for its EXP mode, then it will scan the knobs at power up. This means if you change the knobs whether the unit is off, those values will be how the pedal sounds the next time you turn the pedal on. Additionally, the Tempo and the Sequencer Types are auto-saved and return to whatever they were set to last when powering up the pedal. In these two EXP modes, Ottobit Jr. behaves exactly like all classic guitar pedals work (WYSIWYG). If your Ottobit Jr. is set to either “4 Button Preset Switch” or “MIDI” for its EXP jack mode, then the pedal will simply recall the preset that is stored in the current memory location. This setting makes sure that the Ottobit Jr. functions like a standard multi-preset device for those who depend on recalling exact sounds for performance.
PRESETS IN DEPTH
The Ottobit Jr. features 16 internal preset locations. The first four presets are accessible by a compatible 4-button footswitch and all sixteen presets are accessible by MIDI Program Change messages. To save a preset simply hold the Alt button. The preset is saved every time you edit the “Alt”/2nd layer knobs, this is how the Ottobit Jr. is able to keep your sequencer step settings in its memory after power down. To save a preset to a different location than your current location, either press the desired preset button on a compatible 4-button footswitch or send a Program Change message over MIDI to whichever preset you would like to edit. After you are done with any changes, just press and hold the “Alt” button to save. The Ottobit Jr. can also send and receive full presets for via MIDI Sysex Data. To send a preset from the Ottobit Jr. to your computer, while holding the Alt button, press the Bypass LED (sequencer select) switch. The Ottobit Jr. is also always listening for preset data. Simply send any presets you have backed up on your PC back to the Ottobit Jr. and it will overwrite that preset with the data you sent. If you are happy with the newly received preset, press Alt and the Ottobit Jr. will save that data to the current preset location.
For MIDI preset users, all Meris pedals with a barcode serial number affixed to the back of the unit and packaging include a way to change ALT parameters without auto-saving the current sound. You can now access the Alt parameters w/o auto-saving by holding the Right LED/button while turning a knob. If your pedal has a barcode above the serial number (located on the unit and packaging), your unit includes this feature.
TEMPO IN DEPTH
In the Ottobit Jr. you can set the tempo using one of the following tappings in quarter notes using the integrated Tap switch or External Tap switch, MIDI Beat Clock, Tempo MIDI CC, Tap Switch MIDI CC. The Ottobit Jr. has a very wide tempo range that extends from 23.4 BPM to 6000 BPM. This lets you put the Sequencer in the audio band to allow for ring mod effects. You can even get the Sequencer running at speeds of up to 768000 BPM by using the “Sequencer Mult” control. Both the Stutter and the Sequencer listen to Tap Tempo. That’s also where the “Sequencer Mult” knob can come in handy; it works the way a note division control works, and you get lots of options to have the Sequencer run at a faster rate (although still linked to tempo) than the stutter. For odd meters, try limiting the Sequencer to an odd number of steps, by setting Bsome of the step values to “Skip”.
