The PDF manual isn't ready yet. It should be fairly easy to route things to different tracks in your DAW. Use the Kontakt 16 and in Kontakt add outputs and assign them to your virtual fader channels. Thats what I do in Nuendo. Does anyone want to make an output assignment tutorial for Nuendo, Sonar, Reaper, PT, etc? I know it will be different for each.
I actually do recommend outputing kick, snare, stereo toms, hi hat, and stereo cymbals to seperate tracks. It'll be easier to control sounds. Also, I don't like the Kontakt volume faders, I feel they mess with the Z4 level somehow. Plus, if you route to different channels, you can automate the cymbals to rise in choruses and do some drum effects etc.
Overall, I'm really glad you guys are liking the sounds! As you can see, a lot of work went into them!
We're talking to the Cakewalk guys now about Session Drummer. Its a definite plan.
