This was a good thread as I remember…
Also this blog post by Nathan:
(Btw I am more familiar playing with feedback digitally, and have found maybe a similar confusion when trying to use feedback in e.g. analog modular - I think maybe because digital feedback necessarily introduces a small delay, and/or as James says doesn’t inherently involve noise or irregularity, the intuition feels totally different)
– relatedly, be aware that when using feedback your control block size can really matter for the sounds you’re getting – the same patch at 64 sample block size vs 1 sample block size could sound completely different, because one feedback loop is delayed 64x as long as the other – or you can use Fb1 from miSCellaneous quark for single sample feedback no matter the block size at the expense of performance
In my limited understanding this small feedback delay is also why it is so hard to make a good virtual analog filter…
