Scott, I'll give it a try to answer some of your questions.

Selecting voices or styles depends on your setup. You can set things up to respond instantly to your selection. If you are not properly setup and you try and load a 3GB piano that could take 15 seconds. There are two ways to set this up:

a) High Quality melody voices:

Load all the instruments you need for a certain genre of music on separate channels and change channels to select the different voices, e.g., Jazz:

1 Jazz Organ
2 Flute
3 Trumpet
4 Sax
5 Strings
6 Piano
7 Vibes
8 Jazz Guitar

If you pick high quality instruments for each of the above it would take about 30 seconds or so to load them in kontakt. Direct from disk streaming loads only a small part of each sample and pulls the rest of it from the hard disk as you hit the keys.

b) Lower Quality:

You can do the same as the above with smaller samples but still with a much better quality of sound than most hardware based arrangers or workstations. Alternatively you could use the same wavetable as you use for the Auto Accompaniment, e.g., SGM180, Bandstand and so on.

For Auto Accompaniment I would use a GM Wavetable such as SGM180, Bandstand, etc.

To select variations, fills, intros, etc., I find programming the lower octave of my keyboard satisfactory. You could also program the computer keyboard or a separate numeric keypad. This is not the best in the world but you get used to it.

I don't know about Right Hand harmony but I think Live - Styler has this feature but I don't use it. You can layer voices as many as you want within Kontakt. You might ask the author of Live - Styler (Norbert) more about this.

I don't use lead sheets in the computer but I can't see that this should be a problem. If you can use it on your computer now you will be able to use with all this new arranger software loaded and working.

I like Live - Styler because I started with it. It was the best around in the early days. I still like it. It looks good. It is suitable for use with a touch screen. It can be a little challenging to setup but I have always been able to get things to work. Now I just use it for Auto Accompaniment. I don't use its VST Host feature. I find forte Ensemble to be a superior VST/DXi Host. It is especially well made for live performances. I am one of Brainspawn's forte beta testers.
