Dave.

Finished now Smile.

great digtal noise circuit , i included the timing caps mod for 3 rates slow medium & fast , i like this one Smile.

analog switch matrix is really good when the gate switches are hooked up a random gate module or a sequencer set for 4 steps on a slow clock rate , ideal for slow changing tones or c.v.'s .

here's a pic of the finished module.

Dave.

Nice one Dave.

Just out of interest, what value caps did you use for the rates?

Cheers,
Adam-V
