MIDI / Juno-60 Interface

Two-way communication with Roland Juno-60 synthesizer via MIDI communication. The device controls DCO, VCF, Arpeggiator and other circuits of Juno-60, it icludes own internal LFO. LFO and arpeggiator can be synchronized with MIDI clock pulses. Device distinguishes many MIDI commands and controllers. All parametrs are fully programmable by user. Special DCB cable is included.

MDCB-2 ver. 2 enables Roland Juno-60 synthesizer to be connected to MIDI systems. With help of it, you can remotely control keyboard of instrument and its VCF and arpeggiator by MIDI commands. Hold and Patch Shift functions can be controlled via MIDI too. MDCB-2 ver. 2 enhances DCO functions - Chord mode can be chosen which is not accessible by any other method. The instrument then works like polyphonic MIDI sound expander.

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 - Nr. 1" are converted (by DA converter) to control voltage (VC) for VCF CONTROL input of Juno-60
- command "Control Changes - Nr. 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 or it changes MDCB-2 presets
- command "MIDI Clock" is used to creating of clock pulses for ARPEGGO 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.

Possibilities of MDCB-2 ver. 2:
Receiving and transmitting MIDI channel selection in full range 1 to 16 or "Multichannel" mode for receiving.
The device operates in two directions, it converts MIDI commands Note On/Off from MIDI input to DCB data and transmit the data received from DCB interface to MIDI output simultaneously.
LED indicators of power-on state, edit mode and MIDI buses activity (selectable).
Large support of SysEx Messages for MIDI communication (parameter changes and saving, current status reading etc.).
Internal LFO with 90 selectable waveforms.
Possibility of synchronization LFO and Arpeggiator with MIDI clock.
