Using the Yamaha's Style Creator's "Assembly" feature is still the quickest and easiest way to edit a style. The parts you take from other styles are already assigned note limits and other important data.

Use of the Groove & Dynamics function in Style Creator can also alter the "feel" for the entire style or just parts of it.

The more you use Style Creator, the easier it gets, and editing becomes almost second nature.
