depends whether the flash replaces the hard disk in the menu system. I would guess this is the most logical arrangement?

you could drag to the flash card memory, but then load to composer etc normally. This loading would be then be instantaneous I guess, and saving to the flash card would only take one second, I suppose?

There is no point in connecting up the USB just to fill 3 composers?

Depends whether the panel memories / sequencer etc are still in Ram or in Flash. I would guess they are still in Ram because otherwise editing would take longer with saving to Flash every time?

Besides Ram would not appear as a drive in My Computer...

Maybe the Custom section now addresses the flash memory or part of it?

There are many ways to arrange things, we shall have to see what appears...
