A pretty good all in one solution for working on music. It supports a variety of recording modes for sequencing, but my favorite would be it's TR-Rec mode which is a slightly more limited version of a piano roll sequencer you might find in a modern DAW. It also has real time recording. Plenty of knobs for editing the patches. There is a small amount of menu diving involved for loading samples from a computer. The sound engine is okay, although it sounds somewhat metallic. Its best use may be for writing rhythms and sequencing external gear.
It is capable of producing some great sounding music on its own though.
