The one thing from the videos that I'm still not seeing so far is how you would you save your own settings and presets as in a Kontakt Multi so the next time you load up your instruments, the keyswitches and settings are the same. When working with templates and presets, you need consistency. I always set my keyswitches to the same keys for all libraries being used (depending on instrument range of course). I'm not seeing much point in having the app automatically assign keyswitches for you every time you load up an instrument's articulations (unless maybe your loading an instrument for the first time).
You can program your own desired key switches to note value...
You can easily set that up in Sine and save your project so its the same every time you load it up...
I just setup expression maps in Cubase for the JXL brass and always use the same remote keys as well...
Other options are CC for art changes or even velocity... All depending on what you want or desire
