Does anybody control their BIAB running on a PC with an external MIDI controller (Keypad, iPad, iPhone, etc.) ?

I am NOT talking about using the BIAB App for iPad. It has terrible reviews !

I am talking about one of those iPad apps that lets you customize a user interface control surface to control the BIAB on the PC. Basically I am just interested in transport controls and changing songs. Lemur and TouchOSC are examples of Apps that let you design such control surfaces and communicate their controls to a PC. I'm just not sure how easy it is to hook the incoming MIDI commands from the remote device to the BIAB controls.

Another alternative is using a 64 pad MIDI keypad (like Akai or Novation's Launchpad) with a USB cable to the PC laptop.
