How to use a Raspberry PI as a synthesizer

The Raspberry PI is a popular card-sized computer. In this video, I show how to set up a Raspberry PI V3 as a virtual analog synthesizer with keyboard and knobs for realtime sound tweaking, using standard MIDI controllers and some very minor shell script editing. The result is a battery powered mini synth, creating quite impressive sounds! There's a demo at the start of the video showcasing some sounds I came up with.
