Reply to 4 Bank Mode and Shift. How

Hi guys!

Can anybody give me an answer please to the following questions about mapping my MF?

. How can I make one button a SHIFT button and how do I map the shift function to the other buttons then? Is this the modifier thing? Any help is appreciated.

. My MF has the new update. So this means that I can map 4 functions to each button? Depending on which bank is currently running? If so, please tell me how I map the 4 functions to 1 button with an example.

.Last queston: I want to map a button this way that it starts the effect and changes its amount and when I release the button the amount gets back to the position where it started from. Is this possible?
So I map a button to Effect On, the same button to Inc or Dec Amount, and how do I map the reset after I release the button?

Thx A LOT!
