Discussion about the Korg PolySix synthesizer

This midi interface has been designed by Bojan Burkeljc as you can see on the
bottom of the page. In this first version of the MIDI channel without a midi
channel switch you have to set the midi channel via a sysex massage - described
on the webpage. This channel is stored in the microcontroller, so you don't have
to set the channel every time.

This midi interface only reacts to midi note on/off messages - no further
parameters are supported.

Check if your interface is correctly installed and wired! Otherwise it will not
work!

Info: There has also been a second version of this interface - I made the PCB
for it and Bojan made the necessary software changes for it. You can find
information on this second version of this interface here:

I only have this (my) second version and can say that it works very fine!

Ciao
Peter
