I'm trying to create noisemachine feature to my poly synth by adding simple feedback loop in my mixer subpatch.
I can hear it starts to go to feedback loop but the moment it starts it cuts off the audio. Any ideas why it's not working? Any ideas how to implement this or something nicer? So the goal is to add some Cpu friendly and interesting noise generating possibilities.
If you add a feedback loop, also DC-offsets are fed back, becoming larger and larger (eg. that class A amp can do this).
So when using a feedback loop, you'll always want to use some hp filtering (simple 6db hp-filter is probably enough, put it around 35hz). Next to this, you can also use positive or negative feedback, which will give you different overtones (and besides the negative feedback is able to generate a tone if a dc-offset is coming in, instead of just going up or down further and further. Don't forget to limit/clip the audio in a feedback loop to prevent it from getting too loud.
