Okay, new version:
https://stash.reaper.fm/oldsb/243660/LinReaper0.41.run
I've changed all file paths to be absolute, so let's see if that helps.
I've also fixed the bug where you couldn't pass arguments to reaper.sh, now you can, and I've also added a --help argument, that prints Reapers possible arguments (please correct me if I've misunderstood what an argument does) in a standard UNIX way.
Eric, you're running the same version as I am, so I'm just hoping that using absolute paths will fix the problem, otherwise I'll have to go back to my previous elaborate WineAsio comforting.
