Creating a cross‐fading sustains patch part 3 - M52/fastsampler-downloads GitHub Wiki

If we head over to the instrument editor tab, we can see what our instrument contains. In the instrument editor we have detailed control over zone collections, which are like Kontakt groups.

As you can see there are several groups or zone collections in the instrument. There are two zone collections containing release samples, and two more zone collections that are children of a zone collection labeled "router".

Because Fastsampler tries to preserve as much behaviour as possible, a zone collection with the "router" effect on it was created. A router is an effect that references other zone collections and sets up rules about when those zone collections trigger. In this case there is some behaviour mapped to CC19. When CC19 is 64-127, one zone collection of sustain samples plays. When CC19 is below 64, the other zone collection plays.

In this specific case CC19 controls whether open strings are enabled or not.
