Designed this simple little board a while ago.
It adds individual outputs to a Cheetah MS-6.
It works with a Oberheim Matrix-1000 too but it makes more sense with the MS-6 because of its multitimbral mode.
I know that Gligli worked on the M1000 firmware.
I’m really thinking to get in touch with him and ask if he would work on a multitimbral mode for the Oberheim.
That would be really great.
