That makes perfect sense about not having to be distracted by the UI.
Hearing that explanation my suggestion about Omnisphere would be a Total distraction as it is a very complex instrument. As timidi suggested the sounds are wonderful but they do require more than just a casual tweeking to get them to work in different situations. It would not make sense for someone that only wanted to use the presets that come with it.
I have used the Scarbe RSP73 for Rhodes ever since he released them as they sounded the closest to a real Rhodes to me but I still had to go deeper into Kontakt and tweek it the way I wanted before I was satisfied. I can't even remember the number of real Rhodes stage and suitcases I have owned and sold. I wish I had just one of them back today. I really don't care for the new ones and they are way to pricey for me.
Best of luck with your endeavors as it sounds like a real work flow enhancer.
Kind regards,
Rick
