Hi Jick

I have not noticed any latency, but I am not really listening for it. You might ask Soundtrek directly about limitations on the number of fills and variations per style.

Styles are referred to as "song styles" in Jammer Live. Variations and fills are "band styles". 14 band styles are immediately accessible using a pointer, but these are part of a scrollable list, so the total number of band styles available for a song style is probably greater. Jammer Live allows you to lock band styles when changing song styles so that band styles from more than one song style are available at once. Using locking, I could load about 32 band styles at once. So I would guess that the answer to your question is that a song style can have up to 32 band styles, including intros, endings, variations, and fills.
