Jim Patchell's SMBC

The Synth Module Board - Cheezy Version

via Jim Patchell on the SDIY list:

"When I lost most of my eyesight, I didn't think I would ever do something like this again...but here I go again.

Back around 1999, I did this project:

This board was huge (15" x 10"). And it was so big, building it was a real problem. (Although, back then I could see). I don't remember the component count, but it was a lot.

Well, I got the hankering to give it another try. But this time, I was going to keep it much smaller. I have got the schematic about 95% complete at this time, and after counting the pages, it came to 32. Hmmm....not exactly as minimalist as I intended. I call this one the SMBC, which stands for Synth Module Board - Cheezy.

It includes an AVR X-Mega controller which will do Midi/Sequencer/User Interface duties. Anyway, here is a very prelim schematic.
