For various reasons, I hadn't updated BiaB since the 2012.5 release, even though I had purchased every release (EverythingPAK) since. I finally updated each BiaB release, one at a time, playing a bit with each version to get used to the changes. I had no problems until I installed 2017. With 2017, any of my songs that contain SampleTank voices no longer play those voices, but instead, sound like BiaB has substituted the equivalent GM voice playing thru my default MIDI (Coyote WT) soft synth. When I look at the mixer, instead of showing tyhe SampleTank HQ voice I originally chose, it now shows a voice with the exact same naming, except it includes the word "Sforzando" in it. Also, when I attempt to assign a SampleTank (H1Q) voice to a track, the list of Hi-Q MIDI patches shows every patch listed twice, once with the word "SampleTank" in it and once more withe the word "Sforzando" in it. And if I select the "SampleTank" one, it has no effect in that it still shows the "Sforzando" one in the mixer. And the sound that is played sounds exactly the same as it would if I selected the equivalent GM patch and played it thru my default Coyote WT soft synth. How do I get back the SampleTank sounds I used to get?
