I wouldn't really count on the GW-8 performing like a "workstation". Sound wise this new model is going to be interesting now that it's using Sonic Cell, and Fantom X sounds. However..., Roland has still crippled this unit in the recording area. No user created styles.., limited post editing of user songs.., and the MFX are only there for real-time play. The MFX cannot be recorded into the sequencer.

Personally I think Roland is a bit loose with the term Workstation. You're going to get much better "internal" recording options on the E series. I don't think the GW line is an any way a "Workstation". It's more of a performance arranger IMO.
