This works in SyncTerm. The music plays in the background ... but it also garbles whatever graphics are being displayed on screen.
After looking at cterm.txt, I feel like this sequence is probably not the best. It has some extra stuff in it that I'm sure is unnecessary. I'd like to switch to using the CSI | (pipe) format, but I can't get it to to work.
This is what I tried:
<0x1b>[=0M<0x1b>|B T255O3B8B16O4E4 <0x0e>
Anyway, just looking for suggestions on the correct cterm-compliant way to play a musical sequence, but without screwing up any graphics that might currently be displayed on the terminal.
