iPG-800 is a MIDI Controller iPad app emulating the functionality of the PG-800, PG-300, PG-200 and PG-1000 Synthesizer Programmers that were built by Roland.
It only works with a Roland JX-8P, MKS-70, JX-10 (with Colin Fraser OS or Fred Vecoven OS), Alpha Juno 1+2, MKS-50, HS-80, JX-3P with Organix or Kiwitechnics OS and D-50/D-550.
iPG-800 is a CoreMIDI app and connects to CoreMIDI compatible MIDI-Interfaces that support sysex like the iRig MIDI (e.g. Alesis IO Dock does not work) and to wireless MIDI Network sessions.
Note: No Parameterfeedback for JX-10 with Colin Fraser OS
