I’ve used the External Instrument device method to setup my Push 2 for practice, it’s actually much easier to configure than I anticipated.
I watched this video and followed along (beginning at 4:00, which is where this URL will start the video from):
Those guys offer a free download of the device (with versions for users both with and without Max for Live), however I have been creating my own so far.
There’s some time required, but I found that learning this functionality of Live pays dividends as the only limit to its use is my imagination 
I’m super-hyped for the new website btw!
