Hi Erik,

> Ok, I am glad to hear that you have controll of everything :-)

Yeaahh, after 3-5 days of running around, crying and yelling and going
on the nervs of my family, I finally find a solution for every
synthesizer problem, usually without using a pump gun ;-)

Ok, here you got me, this is the link I wanted to recommend, beside the
diary in my homepage where I listed all problems that I have found so
far. I just wanted to tell you that YOU ARE NOT ALONE ;-)

No, I try to avoid MIDI (I try to use only standard components, no
curtis chips or controller which need firmware). I developed a new
keyboard interface which is theoretically able to recognize 15 Keys in
parallel generating CVs and GATE signals for each key. I tested it with
3 keys in parallel, and the results are good. I know this is not real
polyphonic, but 15 voices must be enough.

OK, so you won't need my help, but I will certainly need yours ;-)
