MarkL,

Welcome to the BIAB forum! I'm a current Mac user, but was on Windoze in a previous lifetime... You say the BIAB accompaniments work fine, so I'm assuming you mean that you can hear them play thru your stereo. If you play the standalone version of TruePianos, do you also hear that thru your stereo? If you open BOTH BIAB AND the standalone TruePianos, do they both play?

In BIAB, the "live" midi keyboard is referred to as the "THRU" track. What do you have listed in your midi input source and as your midi output source in BIAB? This will be found in your settings.

Unless it has changed, BIAB for Windows can only use a general midi synth. I don't believe TruePianos is a general midi compatible software synth (in quickly looking at their web site). I think you could play the standalone TruePianos and BIAB at the same time, but I don't think you can direct your BIAB thru output to this synth while the rest of output is played thru whatever general midi synth is selected in your midi output in BIAB.

I may be entirely wrong about this - hopefully someone more knowledgable will happen along.
