Korg MonoPoly - Modifications


ATTENTION: THESE MODIFICATIONS REQUIRE TO OPEN THE CASE OF THE MONOPOLY. THIS SHOULD ONLY BE DONE BY PEOPLE, WHO KNOW HOW TO HANDLE THE DANGEROUS VOLTAGES INSIDE OF THE SYNTH PROPERLY WITHOUT ENDANGERING THE LIFE OF OTHERS OR THEMSELVES!!! IF YOU DON'T HAVE THE REQUIRED EXPERIENCE - KEEP YOUR HANDS OFF!!! DOING THE WRONG THINGS INSIDE AN ELECTRICAL INSTRUMENT MAY KILL YOU OR PEOPLE, THAT RELY ON YOUR WORK. I WARNED YOU. I REJECT ALL LIABILITY FOR ALL CONSEQUENCES OF THE FOLLOWING INSTRUCTIONS!

Disabling the reset of key assign mode when switching to effects mode

If you enable the so called effects (hard sync and crossmodulation), then the key assign mode is resetted to unisono-mode. This is often unwanted, especially if you use the arpeggiator with different VCO settings and want to extend these to sync or crossmodulation. If you want to disable this simply cut the jumper J1 on the uP/Arpeggiator board KLM-356.

Coming Soon...

  • disabling clock-reset of arpeggio in internal clock-mode
  • changing envelope characteristics
  • various lfo speeds
  • change arpeggio clock to positive trigger slope
  • DIN-Sync Input for arpeggio clock (based on the sync2clock-converter I built for my A100-System)
  • separated triggering of envelopes
  • monophonic arpeggio CV/Gate out
  • polyphonic vcf/vca. I am not kidding: at the moment I am in the developement phase for an addon-pcb which replaces the original VCF/VCA-board and converts the monopoly to a real polyphonic synth.

MIDI-In for the Korg MonoPoly

Yes, believe it or not: there is a MIDI-kit for the Monopoly. CHD Elektroservis from Czechia offers a MIDI-Kit. For more details please visit their site: http://www.chd-el.cz/index.php?id=409

MIDI-Out for the Korg MonoPoly

MIDI-Out can be achieved by a Doepfer CTM64. I did this already with my Moog Prodigy but not yet with the Monopoly.
