Change the decay and pitch of instrumnents. Just absolutely killer. If you don't want to feel like a computer monkey, get off that friggin' PC and get one of these. They travel better too. Incredible for techno and industrial too.
Jazz takes a little work, but very do-able.
I have songs saved to sequencer. The bass sounds are really good, so it provides a nice little rhythm section for my one man band. It makes people's jaws drop sometimes, what fun. I am going to attempt to acquire a new battery in case the one it has fails. Wish me luck.
