Help with Sonic Synth 2/Sampletank MIDI Control

[IvanS]

Hey guys,

Basically, here's my problem. I have an M-Audio Oxygen 61 keyboard and am trying to use the lovely Sonic Synth 2 patches through Sampletank 2 as a live performance synth. The issue I'm having is this: I cannot seem to assign any of the midi controls in either SS2 or ST2(same interface, really) to my keyboard knobs. Other programs like Hypersonic 2 seem to have the easy Midi Learn option which, combined with the M-Audio Enigma software means I can easily check Enigma for my knobs' midi presets and then set the program to midi learn. However with Sampletank2 (and SS2) the process seems to involve setting a number yourself without the whole midi learn thing, and that's where the problem comes in: how do I know which knob reacts to which midi setting since Enigma doesn't have Sampletank2 (or SS2) in it's supported program library??

Basically, my question is this: how do I assign a particular knob (say c15) to say.. an LPF cutoff for a sound?

And secondly, how do I quickly switch between programs within a user bank by using my keyboard? Again, say in Hypersonic2 it's a simple matter of using the + and - buttons on my keys which seem to be pre-programmed for these kinds of program changes, but in SS2 and ST2.5 this just doesn't seem to work!!

Would be very happy for any assistance here, I really hope I can work this out since the Sonic Synth patches are FAR superior to the Hypersonic 2 stuff.
