Chord-Trigger for Korg Polysix and Poly61

Chord-Trigger for Korg Polysix and Poly61 from Florian Anwander on Vimeo.

"This is a demo of an addon module for the Korg Polysix and the Korg Poly61. The addon establishes a trigger input, which triggers the played voices of the synth if an external trigger signal is provided. If no cable is inserted in the trigger input, the synth will behave normally.

This is still a prototype, and the final version will look a little bit different.The addon module will be available as kit and as complete module.

To add the module to the Polysix/Poly61 good skills in desoldering chips are required. It is easily possible to remove the kit and to bring the synth back to the original state.

If you are interested in the module, please visit As soon as I will have the final version, I will announce it there."

Update: the following are some other projects by Florian Anwander:

Most well known are the Korg Monopoly Modifications (and the simplified adjustment procedure)

Modifications for the Jupiter 6:
* adoption of the signal level to the resonance
* linear FM for the Crossmodulation
* Filter-FM
(I can put the sound examples to soundcloud, so you can include them easier)

A very simple addition of a LED to the voicecards of Yamaha CS50/60/80, which makes it much easier to tune the synth.

A DIN-Sync to Trigger-Module
It can be used as 3HU modul or as module in other boxes. Like in a CR-78 (this one is with a prototype board, but meanwhile I have a complete pcb)

Other information that might be interesting is

about the Harms MAC-16, a rare 16-Channel MIDI-CV/Gate converter

a overview about all analog roland filters:

the service manual for the Akai S-612
and also some information about the rare multisampling option for the S-612"
