Another search option that Biab needs is something like Tap2Find in EZDrummer or EZBass.
This can be easily done for RealDrums as you have all the midi

I can put all the RealDrums midi into EZDrummer and do a search either with Tap2Find or with a short midi drum file and I can preview all the found drums in sync with the other tracks directly from EZDrummer, this is how Biab can do it if the midi preview sounds right then you Generate that RD.
I can do the same with EZBass, and having RealChart midi for the other instruments the same can be done.
