Workstations are pretty easy to figure out hammer. My Roland Fantom G7 has a huge lcd screen which provides a lot of data information on any given screen menu. Workstations biggest assets are "professional" sounds and the ability to "craft" your own custom sounds plus a dedicated Sampler on board. I believe the Korg Pa3X has a sampler also though too. I know it has the ability to play and manipulate audio i.e. MP3 files but I think you can also sample and edit sounds on it as well. I'll have to check the specs again on the Pa3X to make sure though. On the other hand, the Yamaha Tyros 4 doesn't have a real sampler on board, which most arrangers don't by the way. The main thing that workstations still lack of course is "full" arranger capability and features such as intro's/endings, style auto-accompaniment, registration feature, song book, harmonizer, lyrics/chord display, etc. On the other hand, the main thing that hinders arrangers, in my opinion, is the mechanical style repetition that make arrangers sound - canned - thus restricting 'natural' rhythm and beat like you would achieve from a real live band feel and sound. The Ketron Audya was suppose to help bridge that gap somewhat with a more randomized style accompaniment but I'm not sure how effective the results have been so far. I noticed that the Korg Pa3X doesn't seem to address that limitation either. Oh well. Hopefully the next generaion of arrangers from the Big Three will. At a reasonable price point too hopefully. Unlike the Ketron Audya unfortunately.

All the best,
Mike
