Sonar Platinum with Akai MPK88

I'm trying to use Sonar Platinum in conjunction with an Akai MPK88 for a live rig.  All I want to do is change (select) tracks with the performance pads on the MPK88.  Does anyone know how to set that up? 

I really appreciate your response! I'm not sure what you mean. The tracks are empty (no recording) I just want to change VST instruments while playing without having to use a mouse to change tracks like changing patches with a foot switch. Am I thinking about this from the wrong angle? 
.

Most stable solution is to change MIDI Channel in the hardware and assign each track input to specific channel. Unfortunately, changing channels on MPK is not a one button press task. So some external processor (hardware or software) is required.
 
The second approach is ACT. You can focus tracks with it and that is the way to use transport buttons. Tempo can not be changed (at least not during playback), but most other Sonar parameters are controllable. As usual, not without caveats. Standard ACT plug-ins have not direct track focusing functionality. So that is possible with my plug-in only (see the signature).
 
If you decide to use AZ Controller, after following "Quick start" (so you know how to assigned an Action list to control), the action list for pad to switch focus to track N  (0...100) is:
* 'Strip' Track <First> +N
* 'Function' "Select strip"
These 2 lines probable make no sense for you now, but after finishing "Quick start" (5-15 minutes, including reading instructions and installing the plug-in), you will know what they are.

I have no problem setting up the knobs and sliders, but can't seem to program the buttons (pads). Am I missing something? Should I have the pads in "program change" or "note" mode? Also, shout I have them programmed in "toggle" or "note" mode. Sorry, this is new stuff for me. I've never used the pads or done any editing with the MPK88. Is there an email address where I can give my phone #? I really would appreciate the help.
