Most Drum Kits require nurturing as many do not quite do what you want. VSTi Drum machines usually contain the ability to change parameters internally and may not obey the Midi volume or velocity data contained in the Drum Track. Drum Soundfont Banks, also differ and may provide what you are looking for without editing. To edit Sf Banks or others, use Edit > Split Midi Drums into individual instruments. Now you can check each track, firstly, to see that all the tracks have sounds allocated. Secondly, because all the individual tracks are using Channel 10, it is necessary to adjust the relative volumes by changing the Velocity levels using Edit > Change Velocities.

Once happy with the overall sounds, multiple tracks can be recorded to wav files separately or in combinations to benefit from Audio effect differences.

Also, in extended format, you can mix and match by allocating different SF Banks/Vsti to the individual instruments. I use BFD but my sound set doesn't include Latin instruments for which I use a specific Latin SF.

I hope this helps.
