I posted this over in the Ketron Forum, it might interest you to know how I use my Audya 5

1) Deleted all user styles (which is just a clone of the factory styles that you have control over) and added only the styles I use (including many modified styles and ones created using style view.)

2) Create USER VOICE LISTS (these are blocks of sounds that can be called up quickly from the main screen). Some of my UVL's are song names others just styles of play. Many of my user voice list sounds are from the PROGRAM section which has my own modified sounds.

3) Link my USER VOICE LISTS to my various USER STYLES so they load when selecting the style

4) create registrations that link to a USER STYLE which in turn loads a USER VOICE LIST.

So basically when I select one of my styles it automatically brings up 10 voices on the screen that I will use with that particular style. Or I load a registration (sometimes I have two or three for a particular song because I am not a good enough player to change lots of things at the same time as playing the keys!).

I don't believe its possible to do this kind of deep level programming on any other board is it?
