Capabilities 5

CV Sequencer (Chain)cv-sequencer
CV mode records RATE knob movements into a per-channel automation sequencer with 2–64 step length.975
Clock Sourceclock-source
Built-in clock generator running 35–420 BPM; CLK OUT provides the clock to the rest of the system.975
Envelope Generatorenvelope-generator
Each channel can operate as a triggered envelope generator with four shapes, retrigger control, and slew/AR mode.975
LFOlfo
Each of the six channels can independently be set to LFO mode with five waveform shapes, rate automation, and clock sync.975
Quantizerquantizer
CV mode includes an optional quantizer with 8 scales selectable via button combinations, with 2 V or 5 V output range.975

Jacks 12 (5 in / 7 out)

NameSignalVoltageDescription
Inputs (5)
CLK INclockExternal clock input; when connected the internal clock is bypassed and the module acts as a clock divider/multiplier. Maximum accepted frequency is 50 Hz.975
IN EmixedDedicated CV/trigger input for channel E; assignable to rate modulation, VCA, trigger, or sample-and-hold functions.975
IN FmixedDedicated CV/trigger input for channel F; assignable to rate modulation, VCA, trigger, or sample-and-hold functions.975
META INmixedGlobal CV input assignable independently to any subset of channels; supports rate modulation, VCA, trigger, and sample-and-hold modes per channel.975
RESETtriggerResets all automation sequencers to step one; each channel can individually be set to ignore this input.975
Outputs (7)
CH A OUTcv-5V to 5VChannel A modulation output; voltage range depends on unipolar/bipolar setting per channel.975
CH B OUTcv-5V to 5V975
CH C OUTcv-5V to 5V975
CH D OUTcv-5V to 5V975
CH E OUTcv-5V to 5V975
CH F OUTcv-5V to 5V975
CLK OUTclock0V to 5V975

Parameters 19

NameTypeRangeBehavior
Automation Lengthmenu_setting2steps – 64stepsSets the number of steps in the automation sequence per channel; selectable as 2, 4, 8, 16, 32, or 64 steps, with fine adjustment using CLK/MUTE.975
BANK buttonbuttonLoads, saves, or switches between one of six stored banks containing all channel settings and automations; also used for copy/paste of individual channel settings.975
Channel buttonsbuttonSelect the active channel (A through F); all knob and button operations then apply to that channel.975
CLK buttonbuttonEnters clock channel settings mode; used to configure internal or external clock rate and divider/multiplier.975
CLK Divider/Multipliermenu_settingSets the clock division or multiplication factor applied to the external clock input; ranges from /8 to ×4 with odd sub-steps accessible via SHIFT+CLK/MUTE.975
CV Quantizationmenu_settingEnables pitch quantization on the CV output; scale type (major/minor, 8 options) is set with SHIFT+A/B/C buttons. D toggles quantization on/off.975
CV Smoothingmenu_settingToggles the CV automation output between linearly-interpolated (smooth) and stepped (regular) playback.975
CV Voltage Rangemenu_settingSwitches the CV output range between 5 V and 2 V; combined with the bipolar/unipolar setting this gives various octave spans.975
ENV Retriggermenu_settingToggles whether the envelope resets from the start on each new trigger or completes its current shape before accepting new triggers.975
ENV Shapemenu_settingSelects the envelope shape: A=decay (RATE sets decay), B=variable shape (RATE sets decay and attack), C=attack, D=pulse (RATE sets pulse duration).975
ENV Slew/ARmenu_settingWhen activated, the envelope follows input voltage changes with the envelope's attack/decay times, enabling use as a slew limiter or AR envelope that respects gate duration.975
Input Modemenu_settingCycles through seven input routing modes for IN E, IN F, or META IN per channel: regular, regular attenuated, inverted, inverted attenuated, VCA, TRIG, and Sample & Hold.975
LFO Shapemenu_settingSelects the waveform shape for the LFO: saw, triangle (sine), ramp, pulse, or random (interpolated); pressing F toggles smoothing on the selected shape.975
MODE buttonbuttonCycles through LFO, ENV, and CV modes for the selected channel; in CLK channel mode starts/stops the clock.975
MUTE buttonbuttonHold and press a channel button to mute or unmute that channel's output.975
RATEknob35BPM – 420BPMSets the main variable of the selected channel — LFO speed, envelope duration, or CV output voltage depending on mode. Also used to set clock BPM in CLK channel mode.975
REC buttonbuttonHold and turn RATE to record RATE automation; hold and tap SHIFT to record trigger events. Double-tap to clear respective automations.975
SHIFT buttonbuttonWhen held and combined with channel buttons, changes the shape or mode-specific settings of the selected channel. Combined with CLK syncs the LFO to clock.975
Unipolar/Bipolarmenu_settingSets the selected channel output to bipolar (−5 V to +5 V) or unipolar (0 V to +5 V); not available in ENV mode which is always unipolar.975
