I looked at the q49 as well. It was multiple ports on the graphite that sold me because i use reason as well and each port showed up as a separate controller which is necessary to record multiple synths in reason. Which non-reason users won't understand.
But for kontakt you can have one instance of the standalone loaded with 64 instuments across the 4 input ports and switch between them all with the graphite. Though this is something i only do in cases of self assured narcissistic moments of uninspired tweaking.
