Thx Machine Claw. There are a variety of reviews on the web, e.g. in:
http://en.audiofanzine.com/virtual-intrument-bundle/native-instruments/cuba/editorial/reviews/the-caribbean-touch.html That state:
“On the lower part we find the different options to trigger a pattern (from Kontakt, or from the host, in any case the individual sounds are readily available), there are Sync and tempo options (the tempo can be increased or reduced by two), a menu to select the pattern,
a button to extract it as a MIDI file (drag and drop), and there's also Edit, which opens a new window, as well as three knobs: Groove (related to the settings on Edit), Feel (beat type, between a robot-like and a more relaxed feel) and Intensity (to modify the overall dynamics).”
I actually thought I saw it in the NI materials but cannot find it now. The patterns are encoded as MIDI and I can find them in the Instrument directory - I could ultimately just use those but they are a little bit of a PITA. I will also try changing the Kontakt options so that it exports the MIDI of the Kontakt scripting in real time and record that into another MIDI track - that also should reflect changes produced by some of the feel/randomization controls. But I was hoping that someone knew something about this "button."
