The Tyros is a good board, although weak when it comes to editing on board. The genesys from Generalmusic has a killer sequencer on board and you would not need a computer to clean up your sequence. For those that are use to using a computer, yes, there isn't a sequencer on board that will compete with a computer sequencer, but for those that have trouble jumping from left to right brain activities, a good on board sequencer is the way to go.
