Which CCs

Newbie question....if I wanted to build a Lemur controller on my iPad to control the Sampletank app (also on my iPad), how would I know which cc's control different elements of Sampletank? I've found a standard Midi CC list, but I guess it is just a generic list. Would I use something like Midi Monitor?

Thanks for your help!

Yeah you would need a list from Sampletank, maybe within the App you can find out or set up the CCs. Or use a Midi Monitor. I use Midi Ox on PC.
