Cookie Run Ovenbreak - soundbank.crb file presumably containing audio

link since the file is way too big

I think this might be where the game stores its midis, but I don't know for sure. I have no idea on how to extract it.

Correct, it's a sort of MIDI/module music containing instruments, samples and information in a RIFF-like format.
Absolutely no idea how to make that thing playable and if CRB is maybe a known format used in some media player (vgmstream? GAP?).

The only thing I have is a generic RIFF parser which will be totally useless but at least it can dump every single RIFF chunk available:

On another note, I decided to extract the iOS version files and they have the midis here but encrypted, apparently with FSB. Any idea on what key this uses?

[aluigi]

It doesn't seem to be FSB encryption, probably just a normal midi with a custom encryption. Can't help.
