I'm working on a simple sequence and am experiencing unwanted and unexplained clicking.

I can't figure out why there are random clicks in this patch. They are all on note starts, but not are consistent.

If anyone can provide me with suggestions on how to tame them, I'd appreciate it.

In this particular case my guess would be it is the amplitude envelope's attack time being too short.

What happens is that the input sognal has a certain momentary value at the moment the attack kicks in. When that momentary value happens to be zero you wont have a click, but otherwise you will, and this is essentially a random process.

Another cause could be the shape modulation of oscb1 (which will jump on the short attack time of the PW envelope), but that one probably won't survive the filtering later.

When patches get more complex it can be vary hard to find the source for the clicking, there really is only one way to find it then - build simpler test patches to try to isolate the problem.

I cant hear any clicks. Surprised
Have you tried power cycling the G2? I got some strange noise once after leaving it on for a few days. Shocked

If I was getting clicks in this situation, I would use the trigger on the oscillator sync. For single oscillator patches, this is ok but detuned oscillators I would avoid this as it doesn't let the detuning free run and can sound a bit like a sample.

Thx both, guys.

Increasing all env. attack times to about 1.5 ms solved it. I should try the sync trick too. g2ian, the clicks are somewhat intermittent; they come and go. Just turned it on this morning, so I don't think time is the problem.
