True, I don't think you're going to be able to do that with a RealTrack piano. In situations like this, I use a MIDI piano and/or bass to write exactly the pattern I want. Mixed in with other instruments with a good MIDI synth, you can sometimes get away with it.

RealTracks are recorded audio performances of at least a measure in length. You are not going to be able to control it more than the quarter note level (and not the quarter note triplet), using slash bass as needed, as BIAB allows four chords per measure. Using pushes can get you closer, but that's on the eighth or sixteenth note level, again not a triplet feel.

The best we can hope for at the moment is to add a post in the Wishlist to allow BIAB more than four chords per bar, and add the ability to make pushes using triplet feel.
