clock source with swing

[fengland]

Hi electronic geniuses,
I'm trying to find or design an analog clock source with adjustable SWING to run analog sequencers. Haven't found a schematic for something like this.

I was thinking I could take an oscillator with PWM, integrate the variable pulse width out to get alternating positive and negative short pulses where the negative pulse timing would be adjusted with the oscillator pwm control - then I could full-wave rectify that to make those adjustible negative pulses positive as well - should make a nice swing clock with voltage control over rate and swing amount.

Does anyone see anything that won't work about that idea? or have a simpler way? or a nice existing design?

Thanks!

Sounds like a good way to solve the problem. I freaked out on the subject a year ago and this is as far as I got.

Your idea sounds much better.

You might want to consider the use of two LFO's where one is synced to the other.

The slave would run (for example) at twice the frequency as the master.

You would clock your sequencer from the slaved LFO and vary the frequency of the slaved LFO to put some "swing" into the beat.

That xor edge detector trick should cut down on components a bit - haven't seen that before. thanks!
