That makes sense. Radium only import MIDI instruments from MMD2 and MMD3
songs. I made Radium to replace Octamed, so I needed to import
my MMD2/MMD3 songs, which only contained MIDI.

I guess you could create a script and let it run over night. Something like

1. Modify S/startup-sequence to load and play the next module.
2. Start a program that monitors the audio output of uae. When uae
stops producing sound, the script shuts down uae.
3. Goto 1.

I've used obsproject.com to create the youtube radium videos. It
performed far better than everything else I tried. Almost no
problems recording glitch-free 1900x1080 at 60hz on my ~10 year old computer.
It's probably possible to script it somehow too.
