Hmmm... sorry about that. I'm back at my daw now.
Try this:
in sonar go to preferences/midi/control surfaces
click add new control surface
select cakewalk generic surface from the list
click ok
go to utilities and select cakewalk generic surface
click the presets tab and select akai mpk49
for each of the transport controls in the right bottom of the screen
click i.e. play, then press the corresponding button on the mpk, then press the learn button
do this for all your transport controls
trust me, a little patience goes a long way here...
i have 4 controllers set up and it took roughly 2 years to figure out an effective and natural way to map them to all the vsts that i use. things as little as "do i always want this knob to control the filter frequency on every synth i use?" come into play -- not to mention situations like what if there is no filter to control?
you'll get it down! the setup can take a while, but it's worth it in the end.
