+audio. It can be a programmable virtual modular synthesizer, polysynth, drone
+box, sequencer, chord generator, multi effect, sample player, looper, granular
+sampler, MIDI generator/processor, CV or trigger generator, anything in
+between, and more.
+
+The Ksoloti Core is a rework of the discontinued Axoloti Core board.  In
+short, Ksoloti aims for maximum compatibility with the original Axoloti, but
+with some layout changes and added features.
