MOOMAH (MIDI-OSC OSC-MIDI Application/Helper)
is a macOS App which translates MIDI messages (Note on/off, Control Change, SysEx) to OSC (Open Sound Control) messages in a fully configurable fashion. MIDI and OSC commands can be entered manually, or there are 'learn' options for both the MIDI and the OSC portion of the Application. Set-ups can be stored as text files, and several 'presets' are included (eg Korg NanoKontrol, Behringer X Code Mini on the MIDI side, and X Air series on the OSC side). Syncing is available (in both directions, where applicable).
