R-Pi, USB MIDI interface, Reaper music workstation software. Low-cost dedicated hardware synth player.
This example creates a low-cost DAW (Digital Audio Workstation) that can be dedicated to MIDI sequence playback for hardware synthesizers or used as a general MIDI/audio workstation. It can be kept as a stand alone appliance, isolated from software update issues, license key issues, viruses and other problems that come up when using a multi-purpose computer for music.
