angelo_maci,

I think I now better understand your question. You can have tempo variation within the style (e.g. within Arranger A the style might start at 80BPM and end with 85BMP within the loop - however the tempo value is fixed accross the style. As suggested above, programing 2 styles separately would do the job - especially since you also want to have time signature differences (not possible now within the same style). If on POWER ON, you load the styles you wish to work with (or copy/replace both styles within the FLASH so they are always there), then there is no loading time as you switch from style to style ... style change will occure at the end of the measure.

Hope this helps.

Thanks,

AJ
