Original features of Roland SH-2 or SH-09 instrument are not changed and it can be used the same way as before the interface installation.

Features:

  • The instrument's keyboard is controlled by MIDI Note On/Off commands including Velocity (can be used for VCF and VCA).
  • The keyboard can be transposed in whole range of MIDI notes 0~127.
  • Next LFO for VCO modulation is added.
  • The interface recognizes Chnl Aftertouch MIDI command (can be used for VCO, VCF and VCA).
  • Possibility of direct control of VCF and VCA via MIDI CC.
  • Instrument's BENDER can be controlled via Pitch Bend MIDI command.
  • Possibility of full control via MIDI CC and System Exclusive communication (changes of presets, changes of paramers values and their storing ino memory etc.).
  • Any receiving MIDI channel can be selected.
  • Optical indication of interface's status defineable by user.
  • 24+1 user's memory banks for setting of the interface parameters.
  • The interface has MIDI output with "Thru" function too.
  • The product is covered by thirty months warranty - more info

Global system parameters programmable by user (can be stored in internal memory):

  • MIDI Channel (1 to 16)
  • ENV Break Pulse Duration (1 to 30 ms)

Preset's parameters programmable by user (can be set via MIDI Control Changes, up to 24 settings can be stored in internal memory):

  • VCO Pitch - Key Shift / Transpose (0 to +79 semitones)
  • VCO Pitch - Aftertouch Bend (0 to +-4 semitones)
  • VCO Mod - Wave (Square / Triangle / Saw-Fall / Saw-Rise)
  • VCO Mod - Polarity (Center-1 / Center-2 / Up / Down)
  • VCO Mod - Rate (0,1 to 10 Hz)
  • VCO Mod - Modulation Wheel Amount (0 to +-4 semitones)
  • VCO Mod - Aftertouch Amount (0 to +-4 semitones)
  • VCO Mod - Retrig (Off / On / Legato)
  • VCF Cutoff - Frequency (0 to 100%)
  • VCF Cutoff - Keyfollow (0 to +-25%)
  • VCF Cutoff - Velocity Amount (0 to 50%)
  • VCF Cutoff - Aftertouch Amount (0 to 25%)
  • VCA Level - Keyfollow (0 to +-25%)
  • VCA Level - Velocity Amount (0 to 50%)
  • VCA Level - Aftertouch Amount (0 to 25%)
  • VCA Level - Volume Mode (Off / CC7 / CC11 / CC7+CC11)
  • CONTROL - Bender Mode (MIDI / Instrument)
  • CONTROL - Indicator Mode (Off / Gate / MIDI Msg / Mod Rate)

Interface recognizes standard MIDI commands:

  • "Note On/Off" (inc Velocity)
  • "Channel Aftertouch"
