Bill:

I perform for dances live, the least thing I want is to have lags, I call them "bumps", this could make my dancers go off their steps, I have none.
In my first reply I forgot to mention that this also works with user styles providing that those are found on my Hard drive with no more than one folder, if you have many "SUB-FOLDERS", you may have issues.

I forgot to mention that also I only work with registrations I pre-programed, I have "generic" registrations like for Rhumbas, Sambas, Tangos, Boogie, etc. from 1 -8 each with different sounds/variations, BUT same tempo.
The registrations work with combination of factory styles and or user styles, make sure the "user styles" work properly, you may have issues with some of those, I make extensive testing in my registrations with any style combination before I perform before audiences.
I have made many Registrations banks and that is how I manage my playing, I know that some people use the MDF, but since is limited to the Factory styles, I prefer to make my own choice of sounds, tempo, balances and also allow me to re-touch the instrument sounds, volume, FX etc on the styles, without editing the style and be able to save those changes in my registrations, it works for me like a charm!!!.
