in 2025, after NOT A SINGLE SOUL ASKED FOR IT, I made a Symantec C++ program (just basic C really) to take in MIDI input from a midi controller and send it back to the same MIDI interface to a Roland MT-32.
gear used:
Macintosh Plus
Anatek Pocket Mac MIDI Interface
Roland MT-32
keytar from Rock Band 3 xbox360 version
Symantec C++ 6.0
Music played: intro to Space Quest from Sierra Online.
