hopefully done with building this. it's a guitar FX processor running on a raspberry pi, with an arduino midi interface to control it, built into a little briefcase thing. took about a week to get it working all the way, still bugs to iron out. the main software it uses is Jack audio connection kit for audio routing, and Guitarix for the actual processing. the RPi also is a wifi access point that you connect to and you can then access a web UI to control functions I couldn't map to hardware.

@alexsleepy rpi4, the 4gb ram one I think. honestly probably overkill, but I want as low of a latency as possible. I'm working on writing up a nice little documentation of the build right now, I'll post a link here when it's done

@ffacidtrip
yeah, latency is the biggest concern when it comes to processing real time audio, I'd also go for rpi4 for this. I think I'd like to build something like that someday

@alexsleepy I need to do more optimizing, but right now the latency is *almost* low enough to not be noticeable. the fact it's being ran headless makes it a bit easier to achieve.
