How I built a amp+cab+effects simulator for guitar on a Raspberry Pi 4B

Also I quit my (NYC) programming job and moved back to my home state of Kentucky.As I got back into music, the lifelong bucket list goal of playing a live show (despite middling guitar and singing skills) started to gain traction in my head. I would come up with a system to automate my guitar tones, lights and vocal effects along with a set of backing tracks.For my first stab at lighting automation, I bought a standard 4-port dimmer switch, plugged in some lamps from around the house and connected the MIDI drum track of an Ardour session to it via QLC+, both of which are amazing open source projects. a show for myself and had zero intention of making this project something many people could use.I set up several sessions of famous songs with lighting tracks and MIDI automation signals to control my lights, Helix and Voicelive. The song only has one guitar tone and no looping so there's no mid-song automation, but the laptop told the Helix (which told the Variax) to drop 2 semitones into my vocal range (ish). So I ditched the Helix and Variax for Guitarix (eliminating the major up-front cost issues), put some session files on github and posted some video examples to a few forums. Alexa already knows all song and artist names and is handsfree -- and ideal combination when requesting backing tracks and playing guitar.Now I'm as skeptical of IoT as the next guy. an acceptable requirement.Content - Needed song rights. Creating all these sessions is going to be a huge lift, but necessary to get where we want to go.Case - At first I had someone "design" (i.e. download a model) and print something for me, but that process sucked. So I worked hard to create amp simulation and effects navigation which you can see in the final video.IoT stuff - This is way more challenging than I anticipated, but AWS provides some solid tools that are satisfying the immediate need.Here's the final "pitch" video.If you are a guitarist or know some (who doesn't?), please visit our kickstarter campaign launching Tuesday April 21st, 2020.
