Well, that was a disappointment. Returned the monitor, returned Win8 (uninstalled).
I have a Tascam DP-24 that is a joy to use and I was trying to recreate that experience on the computer because I'm tired of working with the limitations of the portastudio. What I realized is that having dedicated hardware controls over the transport (stop play rec rew), punch in/out, loop, track arm/select/mute, faders, jog, and EQ is what is needed for a creative experience. Using a mouse with a daw is like trying to eat ice-cream with a straw.
Even on its best day, touch SONAR is still missing half of those things. While I liked the monitor, it introduced compromise to my desk. The music keyboard is now back front and center where it needs to be and everything feels less cluttered, more creative.
If SONAR is to become an effective touch experience, they will need to design a touch version of the UI. Everything needs to have big "playskool" buttons, with big color contrast to show what is selected. They also need to finish the touch control of the transport, but instead of finishing the take lanes, the transport control will need to have big dedicated buttons for everything, much like a hardware control surface. Many of these controls will be DUPLICATES of things you can do with the mouse. Also, the faders need to have MUCH longer throw. It will probably need to take the bottom third of the screen.
Looking at hardware controllers, anything from a Korg NanoKontrol to a MCU will probably work better.
