DESIGNING A CV TRACK

Start with the quantization settings per channel! Select a channel from CH1-CH4, push and hold the SHIFT button and push the QUANT button! The QUANTIZATION menu will appear on the OLED. Rotate the DATA encoder to select one of the preset quantized scales, and the scale is automatically applied. Push one of the first 12 step encoders to select a root note for the sequence! You can also choose the microtonal note input ­ steps are not tied to the specific musical scale or even to notes. To do so, select NONE in the SCALE menu. In this case, the step encoders will move along a grid of cents (see NOTE ENTER below).
When in the QUANT menu, you can design your own scales. To do so, push the DATA encoder and the scale menu will appear on the screen. You can design a NEW scale, EDIT one of the previously designed scales, DELETE the scale or CANCEL the action.

6

Rotate the DATA encoder and make your selection by pushing the encoder! If you choose to design a NEW scale, a new scale design screen will appear. Now you can enter notes in the scale by pushing the first 12 encoders that correspond to the notes.
For microtonal scales, rotate the relevant encoder clockwise to increase the tune for up to 50 cents and counterclockwise to decrease it for up to 50 cents. The OLED will indicate microtonal changes next to the relevant note in the scale. Once done, push the DATA encoder to save and name the scale – select letters by pushing the relevant step encoders and navigate through letters by rotating the DATA encoder, and once happy, push the data encoder to confirm the name.
Now, let’s set the NOTES per step! Select a channel from CH1-CH4 and push the CV button! The default notes are CO, but you can select your preferred default notes in the SETUP menu. Now you can rotate any of the 16 encoders to set the notes per step. Note of the currently adjusted steps will appear in the pop-up screen on the OLED. The OLED will indicate a grid of 16 notes. You can navigate through sets of 16 steps using the buttons. You will have access to the notes within a selected musical scale, set in the QUANT menu in advance. By pushing and holding the SHIFT button and rotating the step encoders, you will advance through octaves instead of semitones.
If the scale NONE is selected in a QUANT menu, the step encoders navigate along the grid of cents, and you can enter microtonal patterns. If you wish to navigate through notes in this setting, push and hold the SHIFT button and rotate the relevant step encoder. When entering notes, you can preview the notes per step by listening to the tune of the VCO ­ push and hold the CV button and push one of the step encoders. The relevant note will be frozen, while the sequencer is running. This is a nice feature during a performance as well. In the same way you can preview the notes, when the sequencer is stopped.
You can also adjust the MASTER GLIDE and GLIDE PER STEP! To do so, select a channel from CH1-CH4, push and hold the SHIFT button and push the CV/GLIDE button! Adjust the MASTER GLIDE from 0-2″ by rotating the DATA encoder. Rotate any of the 16 encoders to set the GLIDE PER STEP time. The per step glide time is linked to the gate length and the BPM. You can select the default glide time in the SETUP menu.

DESIGNING A GATE TRACK
ADDING DYNAMICS

Now, let’s set the GATE LENGTH per step! Select a channel from CH1-CH4 and push the GATE button! Now you can rotate any of the 16 encoders to set the gate length per step. The default gate length is 50%, but you can select your preferred default gate length in the SETUP menu. There are 10 discrete gate length settings, where 0 is gate off, and 10 is full gate ­ the step is merged with the next one. The gate length of the currently adjusted step will appear in the pop-up screen on the OLED. The OLED will indicate a grid of 16 bars indicating the gate length for each step. You can navigate through sets of 16 steps using the buttons.
Pushing the encoders while in GATE page offers multiple functions: 1. Merge gates. Push two or more contiguous encoders
simultaneously and gates of corresponding steps will be merged. For example, if you push encoders 2 and 5, all gates of steps 2-5 will be merged. The gate grid on the OLED will indicate the connection. To unmerge the gates, just push any encoder in the merged gate array. 2. Mute the step. Push the encoder of the step that you want to mute, and the gate will instantly become O. The gate grid on the OLED will indicate the muted step. To unmute the step, push the same encoder again. 3. Skip the step. Push the encoder of the step that you want to skip twice swiftly, and the step will be skipped. The gate grid on the OLED will indicate the skipped step. Please note that skipping steps will affect the length of the sequence. To resume the step, push the same encoder again. Merged, muted and skipped steps are also indicated by the 16 LEDs above the encoders.
For a more dynamic performance, you can assign GATE PROBABILITY per step. Meaning that each step will be played back at specified occasions; otherwise the gate length will be O. To do so, select a channel from CH1CH4, push and hold the SHIFT button and push the GATE/ PROBAB button! Rotate any of the 16 encoders to set the GATE PROBABILITY. If you rotate the encoder counter clockwise, you have access to fractions: , 1/7, 1/6, 1/5, 1/4, 1/3, 1/2, 2/3, 3/4, 7/8. ¼ means, that the step is being played one time out of four, as the sequencer advances through the selected step. If you rotate the encoder clockwise, you have access to probabilities: 10%, 25%, 50%, 75% and 90%. 75% means that the step will be played back randomly on 75% of occasions, when the sequence advances through the selected step. The step grid on the OLED will indicate the probability settings.

For a more dynamic performance, you can also set RACHETING per step, meaning that each gate will be played back multiple times in the selected step length. To do so, select a channel from CH1-CH4 and push the RATCHET button! Rotate any of the 16 encoders to set the RATCHET rate: 2, 3, 4, 5, 6, 7, 8. The step grid on the OLED will indicate the ratchet settings. NB! Ratchet works great together with the per step ARP feature!
A nice feature is the ARPEGGIATOR PER STEP ­ it applies quick arpeggios within the step! To apply the arpeggiation, select a channel from CH1-CH4, push and hold the SHIFT button and push the MOD/ARP button! Now rotate any of the 16 encoders to set the arpeggiator scale ­ the sequencer comes with several built in scales. Arpeggios can be UP or DOWN. UP arpeggios are indicated by + next to the scale, DOWN – by – next to the scale. On the example to the right the first step has semitone scale arpeggio down (-SEMI), the second step major scale arpeggio up (+MAJ), etc. NB! The arpeggiator will work only with GATE RATCHETING. Also nice trick is to set the tracks division for example to 1/4 and length to just 4 steps and add 8 ratchets to each of the steps and then apply arpeggiator per step! You can also adjust number of ratchets per step in ARP page. To do so push and hold the SHIFT button and rotate the relevant step encoder to alter number of ratchets.
For more interesting sequences, you may want to use GATE REPEAT per step. Meaning that each step will be played several times at the same CV, Gate and Modulation settings. To do so, select a channel from CH1-CH4, push and hold the SHIFT button and push the RATCHET/REPEAT button! Rotate any of the 16 encoders to set the GATE REPEAT rate: 2,3,4,5,6,7,8. The step grid on the OLED will indicate the gate repeat settings. You can also program longer notes by applying REPEAT gate merge. In this case instead of several gates one long gate will appear on the gate output. To do so rotate the step encoder to set repeats and push it to merge gates (small + sign will appear next to repeated gate count; push again to unmerge. On the example to the left gates on the steps 1, 3 and 6 are with merged gates, while gates on the steps 5 and 8 are repeated.
To animate your performance, you can add SHUFFLE to the track, meaning that some gates will be set slightly offbeat. To do so, select a channel from CH1-CH4 and push the SHUFFLE button! Rotate the DATA encoder and set the desired shuffle amount for the track. You can also manually design the shuffle pattern. To do so, manipulate the first four step encoders: pushing the encoder will turn the shuffle of the step on/off (a small square indicates that a shuffle will not apply to the selected step), if the shuffle is applied, by turning the relevant encoder you can define, if the shuffle microtiming is applied to positive (+) or negative (-) direction. Your 4-step pattern will be replicated on the all steps of the track.
9

For even more nuanced timing adjustments, you can apply MICROTIMING per step, meaning each step will be played slightly offbeat at a specified time. To apply microtiming, select a channel from CH1-CH4, push and hold the SHIFT button and push the SHUFFLE/TIMING button! Rotate any of the 16 encoders to set the microtiming per step! The step grid on the OLED will indicate the microtiming settings. If the SHUFFLE is applied to the track, it will automatically appear in the microtiming screen.
DESIGNING A MODULATION TRACK
Each channel of the Black Sequencer has a dedicated MODULATION OUTPUT. This means that you can design a modulation track for controlling filters and other modules. But, modulation outputs are not limited to step by step voltages only. Modulation outputs can be configured as follows: 1. Stepped voltages 2. Stepped voltages that correspond to notes 3. Decay envelope with adjustable Decay time per step 4. ASR envelope with adjustable Release time per step 5. ADSR envelope with relative to gate length time settings 6. LFO 7. Per step LFO (adjustable waveform per step) 8. Triggers
Note that each channel can have an individual configuration. In order to configure the modulation output, select a channel from CH1-CH4 and push and hold the SETUP button and push the MOD button. Rotate the DATA first step encoder to set the desired configuration! To exit the configuration screen, simply push the MOD button again!
For example, in order to configure the modulation output for the STEPPED CVs, push and hold the SETUP button and push the MOD button. The configuration screen will appear. Rotate the DATA first encoder to select the CV. Push the MOD button again to return to the per step modulations settings page.
10

In the STEPPED MODULATION (CV) mode, rotate any of the 16 encoders to set the desired output voltage. Maximum output voltage range is from -10V ­ +10V; you can customize the range in the settings menu. The step grid on the OLED will indicate modulation voltage settings.
In the CV NOTE mode the stepped voltages are linked to the notes and you can basically design another CV track. For example, if your VCF tracks 1V/oct, you can mimic keyboard tracking. Note that in this mode, you also have access to negative voltages that are linked to notes.
In the DECAY ENVELOPE mode (the decay starts immediately after the gate is on and the gate length is ignored) rotate any of the 16 encoders to set the desired Decay time per step. The attack time is fixed, and it’s instantaneous while the decay time is linked to the BPM ­ the minimum is O”, but the maximum is always equal to the time of the two steps in the sequence playback. If the ratchet is applied to the step, the max release release time is equal to two ratchetted substeps in the gate. The step grid on the OLED will indicate the decay envelope time settings.
In ASR ENVELOPE mode (release starts after the gate is off, and the gate length is taken into account), rotate any of the 16 encoders to set the desired Attack-Sustain-Release envelope release time. The attack time is fixed, and it’s instantaneous, the sustain level is 10V, and release time is linked to the BPM ­ the minimum is O”, but the maximum is always equal to the time of two steps in the sequence playback. If ratchet is applied to the step, the max release time is equal to two ratchetted substeps in the gate. The step grid on the OLED will indicate the decay envelope time settings.
11

In the ADSR ENVELOPE mode, encoders 1-4 become the Attack, Decay, Release time and Sustain level settings for each channel. In the ADSR ENVELOPE mode the maximum Attack and Decay time is equal to the Gate length, the maximum Release time is linked to the BPM ­ the minimum is O”, but the maximum is always equal to the time of two steps in the sequence playback. If the ratchet is applied to the step, the max release time is equal to two ratchetted substeps in the gate. The maximum Sustain level is +5 or +10V depending on the configuration.
In LFO mode (the MOD output becomes synced or free running LFO), encoders 1-4 become LFO parameter settings. Encoder 1 becomes the LFO frequency control (in sync mode it will set LFO frequency as divisions or multiplications of the BPM), encoder 2 sets the waveshape (available shapes are sine, triangle, ramp up, ramp down, square, random and noise (yes, noise ­ you can use the Black Sequencer as pitched noise generator)), encoder 3 ­ the LFO signal level (-5V ­ +5V max) and encoder 4 turns LFO Synchronization to BPM ON/OFF. The OLED will indicate LFO settings.
In the STEPPED LFO mode, the LFO with the frequency linked to the BPM is available on the MOD outputs, and you can select the LFO waveform per step. The available waveforms are: sine, triangle, saw up, saw down and square.
In the TRIGGER mode, the modulation output will output 5ms +5V triggers, ideal for triggering drum modules or other events in your modular system. Push encoders 1-16 to engage the triggers at relevant steps. For longer than 16 step patterns, use the buttons to navigate to the next pages of 16 steps. The step grid on the OLED will indicate the active triggers.

MANAGING PATTERNS, BANKS AND SONGS The memory of the sequencer is structured in several layers: PROJECTS, BANKS, PATTERNS and TRACKS. A PROJECT is saved on the SD card and contains 16 BANKS of 16 PATTERNS, each PATTERN consisting of 4 TRACKS (CH1-CH4) with all parameter settings. Furthermore, each BANK can contain up to 16 SONGS ­ an array of PATTERNS within a BANK.
SD CARD PROJECTS

16 SONGS

INTERNAL MEMORY

16 PATTERNS

4 TRACKS

You can SAVE patterns at any moment. All the alterations that you make in the pattern are recorded in the temporary memory of the sequencer and will be lost if you switch to another pattern or turn off the unit. A blinking RECORD button indicates that the information has not been saved. To SAVE the pattern information, just push and hold the SHIFT button and push the RECORD button, and all settings within the pattern (all four tracks CH1-CH4) will be saved in the selected BANK and PATTERN. In case you modify a pattern and come up with something spectacular, you may want to save it in a new pattern without altering a current pattern. To do so, push the PATTERN button to open the pattern page, push and hold the REC button and push the step encoder of the pattern slot. Please note, that this way you can save patterns in the empty slots only!
Push and hold the SHIFT button and push the PATTERN button to access the PROJECTS (a set of 16 BANKS of PATTERNS stored on the SD card) menu. Rotate the DATA encoder to select the project and push to confirm. In order to SAVE a new project, push the DATA encoder and rotate it to select NEW. Then push the step encoders assigned to letters to enter the name and push the DATA encoder to confirm. A new project will be available on the SD card for backup on your laptop.

13

Push the BANK button to select the BANK! The OLED shows the grid of 16 BANKS and the numbers in the BANKS indicate the number of patterns saved in each bank (3 and 2 correspondingly in the example shown on the OLED). The LEDs above the step encoders indicate BANKS with patterns ­ the orange LED means, the BANK holds some PATTERNS, while the green means the BANK is selected.
Push the PATTERN button to select a PATTERN within a BANK selected in a previous step! The OLED shows the currently selected PATTERN and the BANK number below.
In order to select the next PATTERN, simply push one of the step encoders for the pattern you wish to initiate, and the NEXT PATTERN icon will appear on the OLED. The sequencer will advance to the next PATTERN as soon the current one is complete (this is defined by the Master Track Length setting in the SCALE menu). If you wish to advance to the next PATTERN INSTANTLY, push and hold the SHIFT button and push one of the step encoders for the pattern that you want to initiate. The LEDs above the step encoders indicate the PATTERNS that have been saved in the memory within a current BANK ­ the red LED means the PATTERN is saved, green means the PATTERN is selected, but it’s empty, while the orange ­ the pattern is selected, and is saved in the memory. Nice performance-oriented feature is PATTERN LINKING. Push and hold the PATTERN button and push several step encoders that contain patterns buttons (you can push the same pattern repeatedly, as well). All selected patterns will play sequentially in the loop. Push any step encoder to select another pattern and terminate the chain of patterns.
You can design a SONG ­ a chain of PATTERNS from one BANK, played back sequentially. In order to enter SONG design mode, push and hold the SHIFT button and push the BANK/SONG button. Now push one of 16 step encoders to LOAD a SONG or open a NEW SONG design menu, if the SONG slot is empty. In total, 16 SONGS are available per BANK, each SONG can contain up to 64 patterns, and each pattern in the chain can be repeated up to 32 times. Green step LEDs will indicate saved songs in 4×4 step encoder pattern.
14

If you choose to design a NEW SONG, simply push the step encoders to design a chain of PATTERNS. The red LEDs above the step encoders will indicate saved PATTERNS that are available for a SONG design. You can push the same encoder several times to repeat the PATTERN. The OLED will show the PATTERNS within the SONG. You can also use the DATA encoder to navigate through chain of PATTERNS and alter or insert some patterns in a SONG. To insert the pattern, navigate to the slot in-between patterns and push the step encoder of the PATTERN, you wish to insert, to modify/replace the PATTERN, navigate to the PATTERN in a chain and push the step encoder of the PATTERN, you want insert instead of existing PATTERN. You can also rotate the the first step encoder to alter the PATTERN number and the second step encoder to alter the number of repeats. You can DELETE the pattern in a chain by pushing the CLEAR button. If you wish to delete entire pattern chain, push and hold the SHIFT button and push the CLEAR button. To SAVE the SONG, push and hold the SHIFT button and push the RECORD button. If you choose to DELETE the SONG, simply push and hold the CLEAR button and push the relevant step encoder. NB! If the song is playing (a sequencer is running) pushing SFIFT+SONG will get to the currently playing song. If you wish to design a NEW SONG, make sure, a sequencer is stopped. Please note that the SONG mode is a performance oriented feature, and it’s not intended to alter patterns while the SONG is playing.
PARAMETER CLEAR, COPY PASTE
You can CLEAR all track information or certain parts/steps/ settings. In order to CLEAR ALL track information, push and hold the CLEAR button and push the track button from CH1-CH4 for the track that you want to clear. For example, pushing CLEAR + CH1, all the information in track 1 will be reset to default settings (eg. all CVs to C0, and all gates to 50%, all modulation voltages to 0V). In order to clear an entire PATTERN, open the PATTERN menu, push and hold the CLEAR button and push the relevant step encoder.
In order to CLEAR all the information in certain steps, select a track from CH1-CH4, push and hold both CLEAR and SHIFT buttons and by pushing encoders 1-16, select the step that you wish to clear. You can also clear series of steps by pushing the first and the last encoder in the series. The step grid in the popup screen on the OLED will indicate which steps are cleared.
In order to CLEAR CVs for a specific track (CH1, for example) only, push the CV button to select the CV menu, then push and hold the CLEAR button and push the CH1 button. All CV information for CH1 will be reset to the default setting (C0, for example). If you want to clear GLIDE settings, select the GLIDE mode (SHIFT+CV/GLIDE), push and hold the CLEAR button and push the CH1 button. All glide information for CH1 will be reset to O”. In the same way, you can CLEAR GLIDE information for specific steps. To do so, instead of pushing the CH1 button, push the step encoders for the steps that you wish to clear.
15

The same goes for clearing GATES, PROBABILITIES, RATCHETS, etc. for a specific track (CH1, for example). In order to clear GATES, push the GATE button to select the GATE menu, then push and hold the CLEAR button and push the CH1 button. All GATE information for CH1 will be reset to the default setting (50%, for example). In order to CLEAR information for specific steps, instead of pushing the CH1 button, push the step encoders for the steps that you wish to clear.
You can COPY and later paste all track information from CH1-CH4 or all settings in certain steps. In order to COPY ALL track information, push and hold the COPY button and push a track button from CH1-CH4 for the track that you want to copy. For example, to copy all information in track 1, push COPY+CH1. In order to COPY an entire PATTERN, open the PATTERN menu, push and hold the COPY button and push the relevant step encoder.
In order to COPY all information in certain steps, select a track from CH1-CH4, push and hold the COPY button and by pushing encoders 1-16, select the step that you wish to copy. You can also copy series of steps by pushing the first and the last encoder in the series. The step grid in the popup screen on the OLED will indicate which steps have been copied.
In order to PASTE all the information from a specific track to another track (for example, if you copied information in CH1 and want to paste it to CH2), push and hold the PASTE button and push the CH2 button. All information from CH1 will be pasted to CH2. If you have copied a series of steps, not an entire pattern, only the steps that have been copied will be pasted. For example, if you are happy with how the first 4 steps of the sequence sound, you can paste them into steps 9-12 simply by pushing and holding paste, and pushing step encoder 9. In order to PASTE an entire PATTERN, open the PATTERN menu, push and hold the PASTE button and push the step encoder for the paste destination.
You can also PASTE the specific settings from the channel, like CVs, GATES, PROBABILITIES, RATCHETS, etc. To PASTE CV settings only, select the CV mode (CV button is ON), push and hold the PASTE button and push SHIFT button. PASTE CV will appear on the OLED. Then select a destination ­ push one of the encoders to paste a step/several steps or push a channel button to paste CV settings to the same steps in another channel. The same goes for other parameters. For example, for glide settings, select the glide mode (SHIFT+CV/GLIDE) and push and hold PASTE button, push SHIFT button and select a destination.
16

DURING THE PERFORMANCE

You can MUTE channels during a performance. Push the MUTE button and push one or several CH buttons to mute relevant the channels. Mute means ­ all GATES and MODULATIONS will be turned off, but the sequencer will continue running and output CVs You can SOLO the channel. Push and hold SHIFT and push the MUTE/SOLO button. Then select a channel from CH1CH2 that you wish to play solo. Gates and Modulations for all other channels will be turned off.

The MAGIC button does magic ­ it randomizes all track information or parameter information within preset scales. In order to randomize all parameters in the channel, push and hold the MAGIC button and push one of the CH1-CH4 buttons! All selected (please, refer to the MAGIC SETUP) parameters for the selected channel will be randomized. In order to randomize a specific parameter, a CV for channel 1, for example, push channel button CH1, then push and hold the MAGIC button and push the CV button. The CVs for channel 1 will be randomized within a preset musical scale, while the glide, gate and modulation information will remain the same. The same goes for Gates, Modulations, etc. For example, if you wish to “Magic” GLIDE, push and hold the MAGIC button, then push the SHIFT button and push CV/GLIDE button.
You can adjust randomization settings, for example the octave range for CV randomization. To do so, push and hold the SETUP button and push the MAGIC button. Use the DATA encoder to navigate through parameters and the first and the second encoders to adjust settings. Here you also can define, what parameters will be randomized, when one of CH1-CH4 buttons is pressed. To do so, rotate the DATA encoder to navigate through the list of parameters and push it to select a specific parameter. A filled dot next to the parameter means this parameter will be randomized. In the example to the left CVs, Gates and Ratchets are randomized, while Glide, Probability and Repeat stay unaltered. Nice extra feature is Gate State (STATE) randomization ­ it randomly turns gates ON or OFF thus altering the sequence without changing other parameters.

17

To add some human expression, when performing the PERFORMANCE mode is implemented. Push and hold the SHIFT button and push the MAGIC button. The OLED will show the performance screen. Here you can transpose selected tracks (push the CH1-CH4 buttons; all tracks are selected by default) and add rolls of current note with adjustable, master BPM synced rate. Rotate the DATA encoder to transpose tracks by octaves or push one of first 12 step encoders to transpose the sequence by semitones. The four bottom step encoders apply rolls to the sequences ­ the 13th step encoder applies the roll to the first track (CH1), the 14th encoder ­ the the second track (CH2), etc. Rotate the relevant encoder to set the roll rate (1/2, 1/4, 1/8, 1/16, 1/32 or 1/64) and push it to apply a roll to the current note in the sequence. While you hold the step encoder, note will continue playing, but the sequence in the background will continue running, so, when the encoder is released, the sequence is in sync with other channels.
18

SETTINGS MENU

The SETUP menu provides basic information about the device status, as well as providing access to default settings and the calibration of the sequencer. Rotate the DATA encoder to navigate through the setup icons and push it to confirm the selection!

The Info menu indicates information about the firmware and bootloader versions. Also, you can perform a manual firmware update/module reboot here. Push and hold the SHIFT button and push the first step encored, and the sequencer will reboot.
In Display settings menu you can: 1) adjust a contrast of the OLED screen (very useful for shooting demos), 2) turn on and set the time for OLED dimming to prevent it “burning out”, 3) turn on/off pop-up screens. When disabled, in several menus (CV,
Gate, Ratchet, etc.) only step grid will appear. 4) turn on and set the time, when a screensaver is activated (highly
recommended feature, because OLEDs tend to “burn out”). Rotate one of first four step encoders to alter a display settings.
in General settings menu you can activate several features that affect overall functionality of the sequencer: 1) turn BAR FOLLOW on/off. If it’s on and you have sequences longer than
16 steps, BARS will change automatically as the sequence advances to the next BAR. Otherwise you need to change BARS manually, 2) turn Master Reset on/off. With the Master Reset on the Sequencer the RST OUT will output the reset signal at the end of the master track, otherwise, the reset occurs on the longest track in the Pattern. Rotate one of step encoders to alter the settings. 3) configure CV output behavior, in case the channel is muted. You can select one of 3 options: STAY ­ the CV output of the muted channel follows CVs of the sequence, while the sequencer is running, FREEZE ­ the CV is halted on the note that was the last used, when the channel is muted, DROP ­ the CV of the muted channel drops to 0V. 4) set the CLOCK OUT ppq. Available options are 1, 2, 4 ppq, and the default setting is 4.
In the DEFAULT Settings menu, you can define the default parameters of the sequencer when the new empty sequence is activated, or the CLEAR function is performed. You can: 1) set the default note value, when the step is cleared, 2) set the default gate length 3) set the gate state ­ if you choose OFF, all gates will be muted, and when
designing a pattern, you need to un-mute them in the GATE menu. Use the DATA encoder to navigate through settings and the first step encoder to alter settings!
19

In the Input and Output CALIBRATION menu, you can calibrate the sequencer to work best in your system ­ you can even calibrate the CV outputs to work best with specific VCOs. In order to perform calibration push the DATA encoder to enter the CALIBRATION mode and follow the instructions on the OLED. NB! The sequencer comes factory calibrated 1V/oct, so, if your VCOs are perfectly tuned 1V/oct, you do not need extra calibration.
In the MIDI settings menu you can configure MIDI inputs and outputs. The menu consists of several pages, accessible by rotating the first step encoder. The MIDI OUT outputs up to four MIDI note messages, note ON/ OFF messages, depending on a gate length and one CC message that corresponds to modulation CV settings (NB: The MIDI CC outputs modulation CV ONLY! It will not out any other modulation settings ­ envelopes, triggers, etc.). Rotate the DATA encoder to select the track and in the first page you can: 1. Select the MIDI channel per track by rotating the second step encoder. 2. Adjust the note velocity. All notes in the channel will have a fixed
velocity, and the Black Sequencer does not have per step velocity setting. 3. Set the pitch bend range that corresponds to the pitch bend wheel range on your synthesizer. The default setting is 2 semitones. This is particularly important, if you are designing patterns in a microtonal scale. In the second MIDI OUT configuration page you can set the MIDI CC message that will transmit the modulation CV.
In the third screen you can configure MIDI INPUT. You can set the MIDI channel that will receive MIDI note and note on/off messages per track.
In the fourth screen you can set the MIDI channel and the MIDI CC that will receive the modulation CV information ­ it will be recorded in a modulation CV.
In the CLOCK setup menu you can select the CLOCK source: INTERNAL ­ the sequencer runs from the internal clock, and you can set the BPM as described above, EXTERNAL ­ use this setting, if you use a master clock from another source. In this case you need to patch a clock source into CLK IN and the the sequencer will indicate a BPM of the master clock, as well as “clock quality” ­ how accurate an external clock source is. The closer it is to 0, the more accurate the clock source is (it does not have undesired jitter or shuffle). By default the sequencer accepts 4ppq clock. MIDI ­ in this setting the sequencer uses MIDI clock from an external source, patched in MIDI IN socket. Also here you can monitor the clock quality. By default the sequencer accepts a standard 24ppq MIDI clock, In order to switch between clock sources, rotate the DATA encoder, and the OLED will indicate a selected clock source.
20

In IN/OUT menu you can configure Input and Output settings. In the INPUT configuration page you can assign the inputs to the channels, meaning, you can use MIDI or CV inputs to alter the content of the relevant channel in various ways, when the RECORD function on the sequencer is activated. Rotate the DATA encoder to alter settings par channel. Rotate the first step encoder to assign the input to the channel ­ here you can choose between MIDI and CV/GATE. Please note that CV and Gate are recorded simultaneously both in MIDI and CV mode. You can quantize CV/Gate to the step grid of the sequencer or you can record it as you play ­ please, refer to RECORD settings below! Rotate the second encoder to select the function of the input. for MIDI Input three functions are available: 1. ADD ­ this means, the CV from the MIDI keyboard is added to the one
in the sequence of the relevant channel. This allows you to use a MIDI keyboard to transpose the sequence. 2. REPLACE ­ in this mode CV and Gate information on the sequencer is replaced by the information from a MIDI controller. 3. MIDI-CV ­ this mode turn one of channels into highly accurate, single channel MIDI-CV converter, and no sequence is present on the output of the selected channel. For the CV/Gate inputs the first two options are available. Same goes with the MODULATION input.
FIRMWARE UPDATE
In order to update the firmware of the Black Sequencer, power off your modular case, remove the SD card from the Sequencer, copy the latest firmware file on the root directory of the SD card and insert the SD card back in the sequencer! Turn on the power on your modular case, and the Sequencer will automatically detect the latest firmware, erase the old one, and upload the new one. Your saved patterns will remain unchanged, and you’ll be able to use them with the latest firmware. To backup or exchange your patterns just copy the PROJECTS folder to your computer.
