Arms is a two voice digital percussion module. It is based around a combination of FM synthesis and ring modulation.

Each voice has CV control over decay length, FM mod range, FM mod decay and the frequency of the ring modulator oscillator.

The two identical voices are designed to synthesize a wide range of drum and percussion sounds, from hi hats to harsh snares and low frequency tom toms.

Each CV input accepts 0-5V signals and is protected from voltages above and under the expected CV range.


  • Length: sets the duration of the percussion sound
  • Mod range: sets the amount of FM modulation
  • Mod decay: sets the length of the modulation
  • Rm freq: sets the frequency of the ring modulation stage oscillator
  • Trig A: gate/trigger input for voice A
  • Trig B: gate/trigger input for voice B
