I've noticed that scroll wheel control of knobs and parameters on Omnisphere is very glitchy and doesn't work too well. Smooth scroll wheel operation is very nice, especially when working with a trackpad laptop, it makes editing parameters much nicer than click/hold and drag. But I usually end of clicking and holding to drag because of how glitchy the scroll wheel editing is.
I'm on OSX 10.7 Lion (latest) by the way.
Is there any way this can be improved? Nice and smooth the way Zebra works would be great.
