Sorry I am running 32 bit. I upgraded to the Mega Pak and I am running BIAB from a external drive. The SampleTank is on my D drive. I initially got an error when I tried to access the HiQ sounds like BIAB didn't know where SampleTank was. I edited Sampletank in the MIDI section so it would know where to find it. Now when I go to change a sound to HiQ it looks like BIAB sees it (no error message) but when I load it I get no sound.
