Using Reaper DAW and software synthesisers on the Raspberry PI 400

Floyd Steinberg

"Using Reaper DAW and software synthesisers on the Raspberry PI 400 - table of contents below! The Raspberry PI 400 has enough CPU power to run multiple virtual synths and effects simultaneously. Let's waste these resources trying to run the ARM version of Reaper with software synths and effects. Reaper on ARM Linux does not have VST or LV2 compability, but we can use Linux' audio subsystem to route our audio and MIDI signals from one standalone app to the next, using even WebMIDI apps within our DAW.
Note: everything shown here will also work on all the other Raspberry PIs. Reaper is a very lean software, so it's a perfect match for the PI. If only it would support LV2 plugins. :-)
