It sounds like you are getting good help, and here's another approach. I don't have PowerTracks Pro any longer (and I don't happen to use RealBand) but in BIAB there is an adjustment routine to synchronize MIDI to audio. This is needed to compensate for drivers and latency in the many possible sound sources people may be using. If this sounds like it might be of use, I can find the command later and you can look for something similar in PTP.
