1) go high, remain high for a random interval of time
2) go low, remain low for a different, random interval of time
3) repeat (with new random intervals every time)

also

what would be the maximum random duration ( you obviously wouldn't want the first on time to be ten years), and would there be a minimum duration.

also

would it be ok if it were at parameter rate i.e. the on and off times were restricted to the nearest 1 Khz tick, or does it have to be at sample rate i.e. the change could fall on any sample.

Does this gate have to be triggerable, or would it be o.k. if it was just a square wave with continuously varying no and off times that started in any state when you started playing the sound and carried on oscillating indefinitely.

It does not need a trigger - just free-running is fine.

On times 5-10 seconds. Off times 5-20 seconds. I'll need to fine-tune them a bit, but these are the right order of magnitude.

Parameter rate is preferred, since it would consume less DSP power.

I really appreciate your help - I figure there must be an elegant solution for this, but I can't quite find it.

One approach might be to put a Constant into a Chopper. Then set the GrainDur and InterGrainDelay to
0.1 s random s

Then multiply your signal by the Chopper.

Interestingly, this seems to work until I click onto another Sound and then click back on the Chopper. When I do this, the expression "0.1 s random s" gets transformed into "((1 repeatingRamp: 1) ?unknown? vmax: 0) s".
