Quick answer

Configure MIDI Captain pedals from your phone

Bosun is the Android companion for the PaintAudio MIDI Captain (10-switch, and experimentally the 6-switch Mini 6) running the open-source Bosun firmware. Configure the pedal from your phone and use Stage at a gig.

Features: - Configure footswitches, banks, rigs, LEDs and expression pedals, then save them to the pedal - Profiles for Kemper Player, Head, Rack and Stage, plus Generic MIDI - Stage shows the current rig, bank, effect states, a tuner and Morph controls - Connect directly over USB-OTG, or through a Raspberry Pi hub on the local network or its Wi-Fi hotspot - Android can route MIDI between the Captain and a USB Kemper - No account required; the pedal connection works without internet access

Requires a MIDI Captain running Bosun firmware, installed with Bosun Desktop. Kemper support is experimental: Head, Rack and Stage have not yet been validated on hardware.
