cool video! I have an spds and I have yet to use the phrasemaker. I deleted all the internal sounds when I got it because I wanted to start fresh and sample my own drums. It is really easy to sample, I pull stuff off of youtube, cds, video games, movies, live instruments. It's really cool.
I learned how to use MUTE groups which is cool if you want to put a bunch of loops on a patch like say a verse loop, chorus loop, bridge loop, and then it is easy to switch between the two loops. It's all in the manual, but I didn't even think it was possible to do something like that till I read it. previously i would play a flam on beat one on two different pads to kill the first loop and start the second loop.
