Re: [PolySix] Low cost note-on/off MIDI for PolySix

2015-04-18 by Bob Grieb

Hello Group,
   I designed a small pc bd that plugs in in place of the PolySix key assignerand adds MIDI note on and note off.  It can also trigger the arpeggiator using MIDI clkwith various divide rates.   MIDI channel and divide rate are set by holding down a key 
at power up, and are saved in EEPROM.  No other features are added.   No MIDI output 
is provided by my design.  

    If anyone is interested, I can supply either a pc bd, or a pc bd and a programmed PIC 
chip if you want to build one.   I don't plan to offer assembled boards.   The pc bd plus 
programmed PIC chip is $27 + $3 S&H to USA addresses.   The other parts to build up 
a board would cost another $10 or so, plus S&H from your supplier.
   I actually have two versions, one for the PolySix and one for the Poly61, since they usedthe same key assigner MCU.   I think it should also work in the MonoPoly, but I have no way 
to test that.
