Thanks for your feedback! I actually just ordered it (it's like like 60% off today on amazon!) Side question: Do you think using USB power could potentially cause latency? I have a Roland Edirol PCR controller (it was given as a gift) and it has caused me so many problems. It took me a while to even get it to work in Ableton and now that it does, I'm getting a bunch of latency. I've been using it USB, but there is the option of using AC power with a midi cable. I somehow either lost the wall wart, or it didn't come with one.. do you think it would be worth it to purchase a wall wart, or do you think it would make a difference? I could use a wall wart and run the midi through my audio interface, but I'm curious whether or not it's just a lost cause.
