Any Kontakt experts here?

Having done a little more research, this seems to be the "Drum Computer", but I"m not finding the documentation - which of the Komplete manuals is this referenced in?

Keys C1-B2 trigger the individual drum kit pieces. Keys C3-B3 trigger 12 programmable drum loops or patterns. The loops and patterns are driven by a script. To edit one of them click the wrench (spanner) icon to open the Instrument Editor, select the Script Editor then the Drum Computer tab. Maybe you've already done that. You can select a pattern by turning the Pattern knob, each one is triggered by a different key. Each pattern has twelve tracks, each of which can trigger a different drum kit piece (set the Track Output key). You can set the pattern, tuning and note velocity in each track and there are several global controls too. It does not show as a Tab (like "Options" or "Instrument" as there is no "make_perfview" in the script. You can add one (for some reason I could not type directly into the script) to get this: Needs work to position things but you get the idea. "Drum Computer" script is described in the Kontakt Library Scripts manual - section 6.2 (at least it is for Kontakt 4). Notice that you've got a Humanizer script there too. Oddly, the Drum Computer (an earlier version) does appear as a Performance View tab in the instruments in the Kontakt 3 Library.

Btw dark star swinging guitar asked me earlier to say thank you on his behalf for the detailed help

Well, I appreciated it even if nobody else did... :D

Indeed. I learned something new. I don't use the Kontakt drums much. I'll have to check this out.
