Yes, Dim Pro and Rapture Pro have drum RX2 samples in this multisample folder:
72 - REX Drum Loops
But I did not see any sfz files that refer to them.
When I load one into Rapture Pro, say, from
Dim Pro (legacy)
Expansion Pack 2
Drum n Bass Breaks
Db_155_K01_Lp03
I see Rapture Pro plays slices across a range of keys.
When I open the file in a Sonar Audio tack and look at the Loop Construction view I see about 16 slices.
But I don't know how the slices map to MIDI notes.
I'm not much of a REXpert, anyone know how that's supposed to work?
