I'd like to be able to set up a matrix of controllers that link to different targets in a sonar project.  Act is too limited for me because it requires the target objects to be in focus.  This is kind of what I'm thinking:

How do you like the graphite controller?

I really dig it!  The only niggle I have are the rotaries and how they are sensitive to velocity of turning them.  I wish there was a linear setting.  The aftertouch works well.  The 16 buttons are great - I typically use those for keyswitching orchestral libraries.  It's a really nice unit.  Bought it after I read Anderton's review http://www.harmonycentral.com/expert-reviews/samson-graphite-49-usb-keyboarddaw-control-surface
It does things my Oxy49 doesn't and vice versa. It's solid in mackie mode and shows track names on the display when you move a slider.  Overall very glad I bought it.
