i have figured out how to control logic 8 synths with the remote sl compact. only took me about 25 tries to figure out spanning one year's time, hehe. well the deal is you have to select the track on the arrange view with the mouse, this will make white and red vertical lines on the track, make sure only one red line is on all tracks, make sure it is on the track you are playing. Note, follow the updated directions on setting up hui and all that, pay attention to the tiny triangles in the environment. Anyway, so when you press the shift button it toggles between instrument and mixer, so click the arrange page, click the track you want to play with the mouse (note: if you use the focus track method on the mixer mode with the controller, it will "select" many tracks with the red lines, whatever those lines are i don't know yet), anyway select only one with the mouse and then press shift to go into instrument mode and viola, the intended instrument is being controlled with your controller. I don't know why the controller selector messes up the focus on which instrument is focused, something to do with those red lines, some kind of selection indicators, those are. Ok hope that helped.
