Axoloti as a synthesizer engine for a Roli Seaboard.
This hack is made at MusicHackDay Amsterdam (2014) by Johannes Taelman, implementing the use of multiple MIDI channels to play one instrument with per-note pitch bend. This was needed because MIDI does not have per-note pitch bend, only per-channel pitch-bend, so the Roli uses multiple MIDI channels to work around this MIDI limitation.
Demo by Micah Fitch.
USB-Host implementation was/is not ready yet on Axoloti, in this demo a PC was used to translate the Roli Seaboard USB to MIDI.
