Universal user-programmable keyboard MIDI encoder

64 parallel inputs for key contacts arranged in scanrow
passive (default) or active (optional) keying
positive or negative active keying voltage up to +/-36V (per request)
on-board diode bridge and voltage regulator - just apply 9-12V AC/DC from adapter or battery
standard on-board DIN5 connectors for MIDI input/output
Optoinsulated MIDI input for merging external MIDI stream or programming the unit
8 analog inputs for continuous control (reading potentiometers or external control voltage)
7 additional parallel inputs for passive discrete control (reading buttons, switches or external TTL voltage)
user-programmable MIDI message of up to 32 bytes for each On/Off/Change event
NOTES about user programming:
- all programming is done by dedicated SysEx messages, format described in documentation
- programmable features are permanently memorized in non-volatile memory
- an convenient MS-Windows-based application mpc64upprg for programming is free downloadable (boards made before 10.2017)
- UpSet and UpSetEx programming utilies for Windows (for boards made since 10.2017, using new programming protocol), free
