General MIDI Player

General MIDI Player has not been tested or confirmed to run natively on Apple Silicon as of our last search, and there is no public documentation from the vendor confirming native support. The app continues to work under Rosetta 2 on M-series Macs today, but Apple is removing Rosetta in macOS 28 (September 2028), at which point this Intel-only app will stop launching entirely. Contact the developer at defectiverecordssoftware.com to ask whether a native Apple Silicon build is planned before the September 2028 deadline. If the vendor is no longer actively maintaining General MIDI Player, consider switching to a more actively developed MIDI player such as Roland Sound Canvas VA, NI Bandstand (from Native Instruments), or the open-source MuseScore — all of which run natively on Apple Silicon and offer comparable or better MIDI playback quality.
