Hi there,
I’ve just been checking out the demo of ‘Neo Soul Keys’ and I’d certainly agree that ‘mic position pots’ are hellish to use - I always have to fight them to get them to move (its not obvious from interacting with the mouse what it is they want you to do exactly - which is a bad sign)!
As far as the GUI goes, I’ve only had a bit of a play around so I’ll keep this in mind the next time I check it out but the main thing that I recognized instantly is that when it starts up initially there is a blank screen for a while which seems odd (5+ seconds)! Instead there is just an empty Halion shell for a while - then it magically appears (see attached) so I agree there does seem to be a certain amount of sluggishness with the gui.
Whether the latter screen issue is a x64 bit version problem I’m unsure - I’m running it on Cubase 7.0.2 (windows 7 x64) but I can’t say that my computer is particularly fast though, its definitely getting long in the tooth (as am I… ha ha)
