Is there any way to control Program Changes via MIDI on the Aura?
The Aura will respond to MIDI Program Change messages to load Programs 01 through 50 remotely. The units basic MIDI Channel can not be changed and operates in OMNI mode, which means it will respond to messages on all 16 MIDI Channels. Therefore, it doesnt matter what MIDI Channel is used on the transmitting device, it will still work. Theres also no setup required, it just works. Our implementation of MIDI Program Change is common to many manufacturers where MIDI Program Change 000 will load Preset 01. This follows on up to preset 50 (i.e. MIDI Program Change 001 will load Preset 02; MIDI Program Change 049 will load Preset 50.) After 50, messages are ignored.
