Hello Everyone...

Congrats on your MicroArranger.

To answer the question on how long are the styles, well, depends on how the style designer made it, keep in mind that any manufacturer does not use only one style designer, they use many, and also depends on the style genre of the music that is made for.

You can not impose a particular style measures-length, "like one size fits all" that wont work. Keep in mind, that could tamper with creativity not to mention to be true to the style to be emulated.

In some big band/Jazz styles, you can make a very long intros....but that is why most Mid size-newer arrangers have at least 3 Intros, from either count in or short, medium and Long.....that the ends are mirror the same way.

A benefit to have longer "loops" in a style, is to break the monotony, remember the first 1980's Yamaha PSR10 and PSR 20, or some early Casios? only one measure loop.....boring.

I hope this answer the question.
