Re: [Linuxsampler-devel] [linuxsampler-devel] "Cannot load file: Unknown leverage controller type"

[Andrew C <cou...@gm...>]

I also tried opening the offending file in Translator 6 Free. It opened
fine and I could see all the programs and preview all the wav samples
inside, so I'm certain the file is not corrupted at least.

I also came across this thread and I see that leverage controller 0x2 isn't
listed there. Seems like it's a bug/glitch that LS is having... :S
