The PianoRoll cc editor can also be used on any Audio Track as well.

There typically won't be any Note Data there, but you can indeed invoke some of the MIDI cc's, such as cc7 - Volume or cc11 - Expression on an Audio Track using the PianoRoll.

Of course, with the advent of the new Volume Node Automation in RB2014, we can now draw Volume Nodes right underneath an Audio Track in Tracks View, which is the easier way to invoke these now.

The OP on this might be better served to hook up both MIDI and Audio output of one of those keyboards or even the WIDI and chooswe to Record Both at Once.

That can be a great way to be able to correct mistakes, as the MIDI Recorded Track easily allows for Deleting Notes, Changing Notes, etc. in the event of a mistake, whereas editing Audio track can only allow one to slice and dice, predominantly.
