You use different Tracks to be able to have several instruments in the Style, just like in a normal Arrangement.
Each Variation of the Style consists of Parts,
one for each Track. The Variations are lined
up after each other.
The Variations may have different lengths, but all the Parts (on the different Tracks) that make up one Variation, must have the same length and be aligned vertically. No space is allowed between the Variations.
