Kenneth of SF is a very dedicated man. He definitely should have a copy of BIAB for testing. I do not believe that there is anything similar to his VST. All other "similar" vst's that support GM midi + Program changes are not remotely close. I spoke to a couple of developers of similar software before Kenneth and they told me that their VST's will remain in "legacy" state and any kind of updates/fixes are not planned.

Why I am writing this? If you find bugs in it, please write to Kenneth, I am sure he will try to address them.
