What kind of signals work with StarLab’s CV inputs?

The following inputs are designed to receive continuous CV input of +/-5V:

• SHIMMER – Sets shimmer gain.
  • SHIMMER knob position acts as an offset.
• INTERVAL – Sets pitch interval for shimmer.
  • Quantized to 1/2 steps over +/- 1 octave range.
• HIGH DAMP – Affects the wet signal high end filtering.
  • Positive voltage opens filter.
  • HIGH DAMP knob position acts as an offset.
• GLIMMER – Sets glimmer gain.
  • GLIMMER knob position acts as offset.
• SPEED – Sets LFO speed.
  • SPEED knob position acts as offset.
• DEPTH – Sets LFO depth.
  • DEPTH knob position acts as offset.
• EXT LFO IN – External LFO input.
  • DEPTH knob acts as attenuverter.
• FEEDBACK – Affects delay feedback or Karplus-Strong string decay/resonance.
  • FEEDBACK knob position acts as offset.
• DECAY – Affects reverb decay length.
  • DECAY knob position acts as offset.
• WET – Affects wet output signal level.
  • WET knob position acts as offset.

The following inputs are designed to receive 0-5V CV input.

• INFINITE – Engages the infinite effect to hold the input signal going into the reverb.
  • Rising edge trigger will toggle the state.
  • Can be set to momentary response by pressing and holding REGEN button at power-up.
  • Set to latching response by default.
• IN GATE – Gates the input to the reverb when CV is high.
  • BLUE INPUT GAIN LED indicates audio input is gated and not sent to the reverb.
  • Can be set to latching response by pressing and holding HIGH BAND button at power-up. Set to momentary response by default.
  • Karplus-Strong mode – Continuously excites or ‘bows’ the string in latching or momentary operation.
• FAVORITE – Toggles between the physical knob/switch settings of the module and the selected Favorite preset setting.
• ECHO ON – Busses the delay output to the WET output to mix with the reverb signal.
  • Can be set to momentary response by pressing and holding ECHO ON button at power-up. Set to latching response by default.

The following inputs are designed to receive 0-5V rising edge trigger CV input.

• LFO CLOCK IN – Sets the LFO speed to sync with phase-alignment to the clock input.
  • SPEED knob acts as clock divider/multiplier.
• TAP/TRIG – Sets the delay time with clock CV input. DELAY/TUNE knob acts as clock multiplier/divider.
  • Clock min 25ms, clock max 3s.
  • Karplus-Strong mode – Triggers or ‘plucks’ the string on rising edge transition.
• CLEAR – Clears audio data from reverb buffer when rising edge detected.

Additional CV Voltage Ranges

• SIZE/PITCH +/-2V
  • Provides 1V/octave pitch tracking of the SIZE/PITCH knob.
    • -2V = 2 octaves down
    • 0V = No size/pitch change
    • +2V = 2 octaves up. Knob position acts as offset.
• SIZE/PITCH (Karplus-Strong mode) 0-4V
  • Tunes string to a range of 4 octaves over 4V at 1V/octave.
  • DELAY/TUNE knob acts as fine tune control over 1 octave range.
