It's great for adding custom sections to the RealDrums.
If you want individual drum control and you can't get it in a particular stem the midi is ok but just may need a bit of tweaking, you can use the PG Sforzando library with the midi as it has a Rock and Jazz Brushes kit that are pretty good. When you get the Playable RealDrums you could use the stems but put a midi stem with it's SFZ in where you have an audio stem issue, you could actually try that now with the ride track with the Rock Kit sfz.
Try: generate up the stems with a stereo mix track included
drag the stereo mix drum track to Drop MID then drag export midi to a folder
drag midi from the folder into Biab
import it to the Ride track (if you have erased it first)
or import to another track
load Sforzando VSTi on the track
load PG Drums Rock Kit
remove the midi notes that are not Ride notes
mute the stereo drum mix and the RD Ride track (if not erased).
