Hi Wakko
Excuse me, do you intend use more than one style during your recording session !? As you can use the 4 main's and 4 Fill's and 2 Intros/Endings of the same style to record a song, I'm confused about what you intend.
The frezze function is precisely to avoide change the style during recording, as we need change the voices and related parameters.
For more complex recording may be the use of e.g. Cakewalk software, connected to 740 (it's possible) is more suitable. I use it.
Give me more topics about your needs. May be we find a solution, as also we must consider other very important features of 740 mainly the high quality voices and 5 DSP's to improve the song recording quality.

Carlos Rodrigues
