Main Features |

  • The interface works in one direction only – it only receives MIDI data. Instrument’s keyboard, knobs, sliders and switches are not transmitted as a MIDI data.
  • MIDI Thru function (no MIDI Thru-box is necessary).
  • Controls the Vermona’s VCOs, VCF, VCA and EG circuits directly from MIDI. The instrument’s tone parameters (control elements on panel) are not MIDI controllable.
  • The instrument’s keyboard (VCOs) is controlled only manually or only by MIDI Notes – not both ways simultaneously.
  • Easy user control of the interface parameters via MIDI CCs (as well as SysEx for experts):
    » 44 MIDI Notes (3 2/3 octaves) range, Velocity sensitive (VCF and VCA control)
    » Transpose function (over whole range of MIDI Notes)
    » Hold pedal – CC #64 (works with MIDI Notes)
    » Legato pedal – CC #68 (tone change without envelope re-trigger)
    » Aftertouch (used for instrument’s VCF and VCA modulation, adjustable range)
    » Pitch Bend (selectable range ±0 to ±12 semitones)
    » User defineable optical indication of the interface status
    » User selectable MIDI Channel for communication
  • 32 internal memory presets to store the interface user settings (the instrument’s tone parameters cannot be stored).
  • Original features of the instrument are not changed and the instrument can be used the same way as before the interface installation.
  • Easy installation without the instrument circuits modification.

The interface recognizes MIDI commands:

  • Note On/Off (inc. Velocity)
  • Channel Aftertouch
  • Program Change
  • Pitch Bend
  • Standard CCs (Hold, Legato, ASO, ANO, RAC)
  • Own CCs (# 16-28)
  • Common MIDI Synchronization – MIDI Clock
  • Common System Reset
  • System Exclusive Messages
