Radium Music Editor

This could be what I am looking for...

But in general use it feels slow and very unstable. I tried on Windows, as that was 'recommended'

I tried this with some of my own OctaMED files, and the experience has been ... well ... not pleasant. None of them load.

Note: I used MED, OctaMED 4, OctaMED SoundStudio, Protracker, before moving to Renoise, Reaper and Bitwig. Also used Samplitude and Sonar for a long time. Amiga user with a large collection of modules and samples I created over the decades. I like trackers and hate pianorolls. I like the Korg Gadget interface, but want a tracker for MIDI.

Have you ever found anything which loads & plays *MED files properly? Specifically MMD2 format files from SoundStudio. I've also got loads I created back in the Amiga days, and I've still got SS itself running on an old laptop but would prefer something that could play/render them to WAV on macOS.
