I use both an arranger and a workstation in my rig. By far the hands down winner for performance changes is the arranger. Between categorized voices and styles to registrations to music finder databases it's all there ready to executed.

The workstation, on the other hand, is nothing compared to the arranger. I have programs which are basically voice patches. I can combine up to 8 voice patches into programs which is essentially a layer. All of this must be well thought out BEFORE the performance. You cannot create an 8 voice layer or patch or keyboard split on-the-fly with a workstation. This can be done quickly on the arranger.

Also, sorting and remembering patch, programs, and performances on a workstation is not very easy. They are numbered and there are very few quick-access keys to use to map to a particuar program. ON the Triton, there is a concept of an instrument group, but there is no way to map that to a quick key and display all those voices within the group. What I had to do was setup my BANKS of sounds by sorting all my Piano's in Bank A, Organs in Bank B, Sax's in Bank C, etc. This is problematic in itself if you want to install new patches from other users or vendors via what they call PCG files. Doing this load will scramble all your Bank assignments and your back to Square 1.

I think the Motif does a better job of this in that you have categorized buttons on the keyboard which map to certain Groups or categories of sounds such as Piano, Guitar, etc. However, on the MOtif you are limited to only 4 layers of sounds for a performance!! Ugh!! So many keyboards, so may different interface designs.

When I look at a new keyboard, I find myself looking more at the Operating system and the ergonomics rather than the voice capabilities.
