So "KISS" is the keyword...(keep it simple stupid) lol. Totally agree. I have a deep love of programming and utterly love using the computer to make sound (im not an analog purist, but still love analog), my goal, 25 years ago was to eventually get rid of all the hardware and just have a really BIG computer. But, I was shocked by how "workflow" (meaning interface's) defined what sounds I was making in the studio.
That's a great methodology with MD2, keep your page counts down. I try my hardest to fit all the "playable" controls on the front page, and the less used to the back. I use it "mainly", to bring large screens to rack mounted synths, I found they never got used because I hated the interface. I use a 12.9 inch tab so my layouts dont scale well sometimes to smaller sizes.
After seeing these interfaces of yours and looking at the demos on youtube, Ive just ordered a copy of Omni, I told my wife it was your fault lol
Oh yeah and I love what you did with the dials on this layout with the labels around the circumference, it looks really cool, Im gonna have to steal your idea sorry. ;)
Cheers
