I've experimented a good amount with long delays, primarily using tapin~, tapout~, *~ + normalize, and omx.Comp~, but a foolproof delay line--resistant to overwhelming feedback buildup-- has proven ever-elusive. If anyone has any patches or advice to share, it'd come much appreciated. thanks

I don't know if it's what you need, but a clip may be useful, though it will had some saturation.

You can also have a >=~ 1. and a edge~ that could detect when you are having a overloading feedback. You can then use that bang to get the delay feedback down.

Hope this help you!


The technique I'd suggest would be more like an auto gain control.

Monitor the level of the signal in the feedback loop (with an envelope follower) and when the level gets above a certain threshold (compare the output of the envelope follower to the threshold level) then the gain gets reduced accordingly. I'd suggest the envelope follower and gain reduction both be set to fairly gentle speeds so as not to create quick changes in the level which could be problematic.

try a compressor or limiter within the signal chain. experiment with different setups(after the feedback multiplier, before, as a substitute for it etc.). also the normalize~ object can come in handy.

(smill's mention of a auto-gain control is a great idea)

Not foolproof, but limi~/tap.limi~ in the feedback path does a pretty good job,
