PIC based synth you can build.

A real analog synth with detunable oscillators using only 4 IC's and custom programmed PIC chip.
DCOs, VCF, VCA. Really easy to build on veroboard.

Check it out at

My poor site has received too many hits - you might have to wait for bandwidth to become available.

Thanks, will check it out this evening!

I noticed you posted another addie in the micro processor section, and I deleted that one as a duplicate posting. However actually that place might be a better place for this, so I'll move this thread to there. Erm ... so there is here now

Jan, you seem confused! I suggest beer. This will confuse you more, but you won't care anymore.

No sorry, the hex file and/or source code will not be available.
I have good stock of programmed chips for sale - with code protect turned on. It was not easy to get the little PIC to do this job you must understand.
I have had orders already so you can understand my reasons.
Hope this is not disappointing.
PICSYNTH.

Fair enough, I have checked them over thoroughly though.
Love pencil and paper (call me old fashioned).

On Midi - no support for.
