It changes programs
Do you believe in change? MIDI Progger does. MIDI Progger changes MIDI programs.
MIDI Progger is an Android app that shows a searchable list of programs. When the user taps on a program, bank and program change MIDI messages are sent via a USB MIDI cable connected to the device. Programs are defined in so-called mididef files. Users can create their own mididef files and place it in a directory named mididef in the phone's storage root.
Definition files are included for the Korg X50 and Yamaha P-140.
