With windows 7 64bit I got sampletank 3 working this way. 1) installed Jbridge, 2) ran jbridger, selected 32bit host, 4) set it to individual plug in selection and then searching for the folder the original 64bit sampletank3.dll was installed, 5) let i write a 32bit version to the BIAB folder, 6) chose the creates sampletank3.32.dll as preferred VST plugin from within BIAB's dxi selection menu, thus as default VSTi synth.

One question regarding ST3 remains: has any one created successfully a GM sound set to be working autoloaded from within BIAB booting for Sampletank 3? Seems either a lot of work, as with Sampletank 2.5; i gave it up with too many errors on the way to get it working). Or is it not possible at all maybe? I had Hypersonic 2 working before, but you always had to reset it to GM modus first within the plugins GUI after booting BIAB. - F
