My single biggest wishlist feature is a native device which drops into the FX chain, routes audio out to a selected output, then brings it back via a selected input.
The key piece is that the send/return latency is compensated for as part of the PDC calculation. Bitwig’s implementation of this is a perfect use-case example: you click a button which sends an audio ping through your FX loop, measures the round trip latency, and auto-compensates.
Would be cool to have internal audio sends and returns as DSP for anywhere in the audio chain, so we could create feedback loops. Would perhaps be wise/necessary to have a limiter component enabled by default in such situations
That be awesome, Ableton Live had this in sends - send A to B to C and back to A, watch out for feedback noise…
Not sure if I mis-remember, but I think there is a secret workaround that can achieve feedback loops somehow? Might be a corrupted memory, or it has been patched out already? 
Control signal feedback is possible using a Hydra, which can create some cool chaotic effects modulation. As far as I know there isn’t a native method for audio feedback, but if you can find it or dig it up I am definitely, definitely interested!
I did a video quite a while ago about signal feedback in renoise which I will post here when I find the link
Ah, here it is:
This could probably be done with an audio output configured to loopback, and a subsequent Line In device setup to capture the loopback input
Loopback outputs on your audio interface (or virtual interface e.g. Black Hole, if you’re on OSX) and Line In devices to capture the return.
Hmm I’ve got black hole. Guess I’ll have to tinker with it and see if it works for this. I usually use blue cat connector for feedback loops, but I’m always keen on more native solutions. Thanks for the idea
Yeah it’s a hacky solution, not ideal, but maybe worth trying for shits and giggles. Wondering what the latency would look like as well.
EDIT: I just tried it. The round trip through Blackhole adds about 15ms latency with audio settings at 96 kHz, 5ms system latency. Upping the system latency also ups the round-trip latency of audio through Blackhole.
