Crash Sync plus...

How about a Crash Sync type circuit, except driving multiple parallel oscillators all at different frequencies?  Or perhaps one oscillator syncing another, syncing another, etc, in series...?  Harmony, pulse-code modulation...  :icon_eek:

I just bought some 4093s so I'm gonna give it a try.  Will post results.

I can't even begin to comprehend what that will sound like... but I know I want one.

I just played with a 4093 for the first time.  Wow, these things are fun!  I haven't even touched a guitar yet and I'm having a blast.  ;D

I have a batch of 4093's, and am into 'orrible noises, so count me in........!

I had a similar idea the other idea only thinking about 40106 inverters for the oscillation instead.  Please post clips when you get it going.

I'm still in the "getting to know you" phase with these chips, but so far I'm pretty impressed with the potential.  Last night I confirmed my hunch that you could make a PWM out of the standard Schmitt trigger RC oscillator by simply injecting audio (through a cap and limiting resistor) to the input.  It's funny because other than the oscillation, it works about like a typical CMOS inverter gain stage.

Now I'm trying to figure out a way to get a full-wave rectified control signal out of a pulse width modulated control signal, so I can get some envelope control out of this... and if I can do it all with switching, even better.
