Hey I figured I would share this before it get s anymore complicated. It is not a complete drum machine sequencer yet only the pattern editing is done. I figured it would be good to share it as is so you can add your own drums, triggering, and preset saving. So far it has a 16 pattern memory with 4 drum channels. The pattern storage goes into 4 arrays - 1 for each drum channel. Each pattern array is 256 bytes? Should be 2 bits but hey.
You should add a loadbang to set the initial values of pattern, BANK, and D_SELECT. I didn't want to clutter it up for future preset saving.
I ought to be easy to add more pattern memory and more drum channels.
If anyone can figure out a better - less atom way to implement the color changing of the toggles or anything else in the patch I would be glad to know.

I have the patch producing drum beats now using sampled drums but need to work on it some more before sharing.
