Bass.dll?
 

Can anyone tell me what exactly this does?
"bass.dll"
I find it in the graal folder and well, Since I removed it from the graal folder, it's still running. So what does it do??

Eh well after my computer's sound drivers locked up while playing graal, I figured I might as well figure out what was causing my 64 bit windows to crash. It might be completely wrong, but I got a feeling that the bass.dll file is 32 bit and causing me a crap load of errors which crashes my client. And the occasional sound driver glitch, hurts my ears.. its too loud! 108dB is very loud when you have some decent headphones....

** Graal even launches after a few attempts in my 64 bit windows, it still crashes at random unless I run my TS client like normal.

I think bass.dll has to do something with GraalEditor. If not, then I don't know ^^

bass.dll was used in Graal v2 and is still used by the GraalEditor.exe which is based on v2. It is not used by v4.
