I built a amp+cab+effects simulator for guitar on a Raspberry Pi 4B
Great article, I wish I'd seen the mid-project posting to HN. I was skeptical about the Alexa integration but that seems to work well.>  ludicrously difficult to set up. Laptop + low-latency Linux + Ardour + QLC+...This resonates [sorry] with me. Linux sound today seems painfully reminiscent of Linux X-Windows 20 years ago. There's a lot of painful voodoo, competing control systems and legions of mostly out-dated forum threads of dead-ends, anecdotal advice, misinformation. I'm hoping that the next Ubuntu Studio will Just Work on the laptop that I have put aside for it and that I won't have to waste more time in the Pulse/Alsa/Jack soup.I was aware of Guitarix but have not yet played with it. My youngest is learning electric and we've got to the point where we can play together, with me pounding out the bass line on an old classical we had lying around(!). That is a blast but I wasn't really intending to become a bassist. If I were to pick up an electric guitar to fool around on, can Guitarix drop me down an octave and make me a pretend bass player? (I had a quick poke around the Guitarix wiki, couldn't see anything). There must be DAW processing plugins to do this, but I'd really like to be live. Are there other solutions? (apart from buying more instruments I mean...).Oh, and I love this:> So I bought a 3D printer and became a CAD guy, I guess"I had a hard problem to solve... so I... casually nuked it" :)
