I've got wavebank and adpcm support working in Monkey Island Explorer. So rather than update the music extractor the music dumper will be integrated into MI Explorer from now on.
This has a few advantages:
1 - I've got adpcm playing correctly now so there's no need for the lossy conversion to pcm wav that there is currently.
2 - I can use SKA-T's mappings to add correct/more descriptive filenames to all sounds and music.
I just need to polish and test it a bit more and should release the new version in a few days.
