MDCB-2 : MIDI / Juno-60 Interface


FUNCTION ^^^^^

Signal from MIDI bus coming to input MIDI-IN is isolated by optocoupler and brought to CPU. CPU picks data for MDCB-2, converts these data according to parameters settings and final output data is sent to output connectors as the signals for Juno-60 control:

  • commands "Note On / Off - Note No." are converted to data for DCB input of Juno-60
  • commands "Note On - Velocity", "Key Aftertouch", "Channel Aftertouch", "Control Changes - No. 1" are converted (by DA converter) to control voltage (CV) for VCF CONTROL input of Juno-60
  • command "Control Changes - No. 64" is converted to gate-signal for PEDAL HOLD input of Juno-60
  • command "Program Change" is converted to trigger pulse for PATCH SHIFT input of Juno-60
  • command "MIDI Clock" is used to creating of clock pulses for ARPEGGIO CLOCK input of Juno-60
In the opposite communication direction, data from input connector lines of DCB IN/OUT are processed by CPU and sent in MIDI format to output MIDI-OUT. MIDI-OUT output is at the same time being used for SysEx communication of MDCB-2 and host system.
