Hey Mike,
I noticed it's been awful quiet on the yahoogroups. Been busy?
I've been working on and off on this STM32F4 synth chip.
It's been a slow progress, but I think I may have something almost usable here.
Here is a private/unlisted video..
I'm keeping this quiet for now because I'm not sure if I want to share the work I've done so far with the public.
Anyway, take a look and let me know what you think.
