Clicking on some Farfisa patches

[functionform]

I've noticed there is a muted sort of click happening on a few patches.  I assume this is modeled intentionally since I can hear go through the effects.  (for example it will get delayed) Can anyone shed a little light on this?

I'd like to turn it off, as I love getting nice textures with this, but the click brings me out of it.

CPU usage is low btw, and I'm very sure I'm not causing clipping.

I've noticed this happens in standalone a lot more, and in Reaper when I don't have gui visible and after some time the click pops seem to go away.

I will help a lot if you named some factory preset that have the click you mention.
