1) the same, but the difference will be the SD card which can load a set of just panel memories in less than a second.

2) the way around this would be to create your own count or drum intro in a composer intro which can be at max volume, max velocity etc, but then you would have to load composers for your styles rather than use the presets, I suppose. Use a single composer intro and switch to a panel memory with the preset style just as the 1st chord starts? Use the mic if you start yourself?

3) the extra outputs are fully assignable for send /return or monitor purposes. All 24 parts can be assigned in mono or various combinations of parts in stereo. It is not a subwoofer output, that was an incorrect rumour from bad info at Frankfurt.
