Main unit

  • Dimensions:
  • Weight:
  • Power supply: 12V DC, 2A center positive barrel plug
  • Audio output: 1Vpp max
  • USB: Micro-B connector @ USB 2, presents a USB-SERIAL and USB-MIDI device
  • MIDI: TRS 3.5mm Type A, MIDI In only
  • Bowing range / Motor frequency range: ~30 Hz - 650 Hz[1]
  • Max string length:

Control box

  • Max CV/Gate voltage in recommended: 12V
  • Voltage range with no attenuation: 4.096V
  • ADC resolution: A0-A3 @ 16-bits, A4-A7 @ 12-bits
  • Input configuration: A4 and A5 configured as trigger-inputs which reads new data once when the input voltage has passed a certain threshold, all voltages under the threshold are recorded as 0. All other inputs are configured as regular inputs that are continuously read and their values recorded.
  • CV input ring voltage/current for expression pedals: 5V @ 5mA / jack
  • Audio output: +/-5V / 10Vpp

Notes

  1. This is an approximate range for the first generation of bowing motors
