This has been said before, you need all the RealDrumCharts in a database.
These can be match as below or having a small checkbox beat creator this will find the best match RealDrum to the entered beat and be able to play back the midi in sync to the other track/s.
This can be done for other instruments also. Can you see the possibilities ?
You should be able to select a section of BiaB track with all the RT instruments in the search and be able to select one instrument in the filtered list and it will generate that up for the section of track and play/loop,
then when you go down the list it will do the same for the next instrument, you want it played back in situ not just a wma demo.
All this without going in and out of the jailhouse pickers.
