I use MIDI Designer Pro my iPad to control mixer sliders, VST parameters, parameters of the DAW's native DSP effects, trigger notes, enable/disable tracks (channels), transport controls, etc. The DAW (Renoise) supports MIDI learn on nearly everything (as well as OSC protocol). It allows me to set up only the interface controls I need to manipulate during the performance on the iPad rather than trying to chase it all down in the DAW. I have been pretty happy with this setup.
