Clock divider circuit

[Caustic]

I think I talked about binary ripple carry counter for a different application, but I wonder if the 4040 would work for your project.

Any one using the 556 for a dual voice oscillator? [not 566]

You could also thicken this up with a CD4040B 12 stage binary ripple-carry counter. 12 stage is kinda overkill, but whatever. [image] What you do is setup one 555 as an astable circuit, then feed the output (pin 3) of the 555 into pin 10 of your ripple counter. Then, the buffered outputs (Q1-Q12) will then give you 12 octaves worth of frequencies. Combine this with a op-amp mixer, and you got a mighty chungus of a voice. What might be more musical though, is having a 1 pole, 12 position rota…

It would give you more stages from the look of things.
