How to use a Raspberry PI as a sample-based synthesizer / ROMpler

Описание: How to use a Raspberry PI as a Sample Synthesizer / ROMpler, using Audacity, SWAMI and QSYNTH. Also: How to use an external USB audio interface with your Raspberry PI. Table of contents below!
In this video, I'm solving the problems with my audio interfaces I encountered in my last video, install some audio software and build a sample-synthesizer (think Korg M1, or any workstation synth) from scratch, creating a string orchestra sound on the way. There's a handful of audio examples of the piano&strings variety in this video.
