C-3 Knob Recorder

Flame

Capabilities 1

CV Recordercv-recorder
Three independent channels each record knob movement and play it back as 0–10V CV; track 1 also accepts an external CV input summed with the knob. Supports one-shot and loop playback with per-channel speed and offset control.1044

Jacks 5 (2 in / 3 out)

NameSignalVoltageDescription
Inputs (2)
CV-1 Inputcv0V to 10VCV input for track 1 only; its voltage is summed with the channel 1 knob position, allowing an external CV source to be recorded. When the knob is at zero, the input CV is recorded directly.1044
RESETtrigger0V to 5VCommon reset input for all three tracks; a high pulse resets all active tracks and restarts them in their last configured play mode.1044
Outputs (3)
CV Out 1cv0V to 10V1044
CV Out 2cv0V to 10V1044
CV Out 3cv0V to 10V1044

NameTypeRangeBehavior
Knob 1knob0V – 10VIn KNOB mode, sets channel 1 output voltage directly (0–10V); summed with CV-1 input. In PLAY mode, controls either playback speed or output offset depending on the active function. Acts as an offset ruler — knob position at zero allows recording pure CV-1 input signal.1044
Knob 2knob0V – 10VIn KNOB mode, sets channel 2 output voltage directly (0–10V). In PLAY mode, controls either playback speed or output offset for track 2.1044
Knob 3knob0V – 10VIn KNOB mode, sets channel 3 output voltage directly (0–10V). In PLAY mode, controls either playback speed or output offset for track 3.1044
KNOB Buttonbutton—Activates manual KNOB mode for the channel. Holding it while pressing PLAY toggles the knob's play-mode function between SPEED and OFFSET.1044
OFFSETknob-5V – 5VShifts the CV output up or down by up to ±5V from the middle knob position when OFFSET function is active. Output is clamped to 0–10V.1044
PLAY Buttonbutton—A short press (under 0.5 s) starts one-shot playback; a long press (over 0.5 s) starts loop playback. Also used in combination with the KNOB button to toggle the knob function between SPEED and OFFSET during play mode.1044
RECORD Buttonbutton—Starts or stops the recording sequence for the channel. While recording the LED blinks yellow; pressing again stops recording and automatically enters PLAY loop mode.1044
Sample Ratebutton50Hz – 100HzSelectable at boot between 50 Hz (102 s max record time) and 100 Hz (51 s max record time). Setting is stored and reloaded at next power-on.1044
SAVE Buttonbutton—Saves all track data to non-volatile memory when all channels are in KNOB mode. Holding SAVE while pressing a channel's REC button saves only that individual track.1044
SPEEDknob—Controls playback speed via the knob when SPEED function is active. Knob at zero gives half speed; knob at maximum gives fourth speed; middle position gives original record speed. Active by default after power-on.1044
Zones
Half Speed
Original Speed
Fourth Speed
  • Half Speed -100–-100%At knob position zero (fully CCW), playback runs at half the original record speed.1044
  • Original Speed 0–0%At middle knob position (noon), playback runs at the original recorded speed (1x).1044
  • Fourth Speed 100–100%At maximum knob position (fully CW), playback runs at four times the original record speed.1044
