Ever since I first purchased VE Pro 4, I've been experience a problem loading patches in Kontakt, Geist, and Maschine. Particularly in Kontakt, if I don't have some channel armed for recording, the patch I attempt to load will not execute. I must take 2 steps most of the time:
Step 1: Arm any track of the Kontakt instance for recording
Step 2: Press the sustain pedal.
This same experience occurs in Ve Pro 5. Here is a video of it:
I use Ableton Live in this video, but it also happens in ProTools and Logic.
