* Will you miss the variety of extra sounds, or do tou tend to use the same "bread and butter" sounds ( like I do )

* Styles - this area is more specific to your playing style. I like variety, but I can get by with mimimal styles because I use so much live manual bass and chord accmt, so even a rhythm pattern used many times per night will sound fresh because of the backing.

* performances are collections of data, like registrations in the Yamaha world. Mayne people play arrangers without ever using any performances, and some rely on 1 for each specific song style. Performances memorize styles, tempos, sounds etc.

* Voice processor makes it easy to REsell, if you tend to buy and sell alot.

* I have never used a sampler. I let the factory do the hard work.
