Sorry if this has been discussed before - I just bought Kontakt and Scott's tutorials.
Scott keeps saying that you can select and set different sounds to different notes, for example in the Urban Beats drumkits. It seems to me that the configurations are preset and that by clicking on the Note dial, or selecting an instrument under the Selected Instr menu, you are only changing what is displayed on the Kontakt interface.
For example, load 087-African Night (as in Scott's tutorial). Play C1 and you get "Sub Bass" as the instrument. The Note dial also points at C1. (Click it for info)
Now, go to the drop-down menu under "Selected Instr" and select Short Snare. The Note dial moves to show Db1. Play C1 - it is still set to Sub Bass. No change. The Sel by MIDI switch has no bearing on this either.
I see no way to assign different instruments to different keys (apart from going into the Mapping Editor of course).
So, it seems to me that, unless I'm missing something, Scott is wrong about this. Same applies to all other similar settings as in World Drums etc.
