For the purpose of better mix options, you may want to consider multiple tracks of the same kit. Then assign the midi note data for different drum parts to different physical tracks of the same the same kit. This will allow for far more detailed mixing, as in separate audio mix channels and FX for certain sounds. I tend to use four instances of the same kit. This allows for separate kick, snare, hats and the rest as a stereo.
This of course will increase CPU usage. But the kits are really very low CPU sample playback devices, and don’t consume too much.
Maybe one day we will see something like VSTi implemented within Cubasis, and the associated routing and sub mix options. This would be awesome for routing individual outs, of say a kit or multi timbal synth to separate mix channels, while only using one instance of the instrument.
Hope this helps.
Cheers,
Dave.
