Not really sure how to explain what is going on in my patch. Can someone please download and try to reproduce what is happening to me?
I made this patch that uses a [delwrite~] and [vd~] combo to do pitch shifting. All is fine 'n' dandy. When I try to add feedback, it sounds really cool. Then, after about 30 seconds of messing around, I hear a strange sound. Kinda like that weird noise when a signal goes past the Nyquist limit and begins to "bounce back" (at least, I think that's the sound). At first I didn't know what was going on, but I can confirm by looking at the vu~ meter that --somehow-- something is feeding back at a ratio greater than 1 and slowly gaining volume until I am forced to mute everything.
Keep in mind this takes like 30 seconds to develop, but when it does, it's horrendous.
