Hello Group,
I designed a small pc bd that plugs in in place of the PolySix key assigner
and adds MIDI note on and note off. It can also trigger the arpeggiator using MIDI clk
with 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 used
the same key assigner MCU. I think it should also work in the MonoPoly, but I have no way
to test that.
