Pluck (2hp) Cheat Sheet

Karplus-Strong string synthesizer with 4-voice polyphony for resonant, percussive, and melodic string timbres in Eurorack.

Quick Reference

Inputs

Jack Function Voltage Range Notes
TRIG Trigger input - Triggers a new note (up to 4 voices)
DAMP Dampening amount CV input -5 V to +5 V Modulates harmonics/tone on new notes
DECAY Decay amount CV input -5 V to +5 V Modulates decay time on new notes
V/OCT 1V/Oct Pitch input 0 V and up Adds to pitch knob (standard scaling)

Outputs

Jack Function Voltage Range Notes
OUT Audio output (main) 10 Vpp Main module output

Controls

Control Type Description
DAMP Knob Sets string dampening (harmonics). Left = dull, right = bright
DECAY Knob Sets decay length. Left = short, right = long
PITCH Knob Sets fundamental pitch. Active for latest note, even if sustaining
Out LED LED Visualizes output amplitude

How to Use

  1. Patch TRIG to a gate/trigger for plucked notes. Each new trigger can play a new polyphonic voice (max 4).
  2. Set DAMP knob/CV: Left for muted/plucky, right for bright/ringing. CV (-5V to +5V, summed with knob).
  3. Set DECAY knob/CV: Controls how long each note rings. CV (-5V to +5V, summed with knob).
  4. Tune with PITCH knob/V/OCT: PITCH knob provides coarse tuning; add V/OCT for external pitch control.
  5. Monitor OUT/LED: Patch OUT to mixer/audio, use LED for level reference.

Power: +12V (83.45mA), -12V (4.5mA) | Depth: 42mm | Width: 2hp
