What's your favorite video out there about the JJOS XL?

Just trying to find out about the available resources - besides the manual - while I wait (very ANXIOUSLY! ) for the upcoming (PLEASE!) "Beat Making on the MPC 2500 for JJOS XL"?
Please help me learn it...
Thanks!

best thing you could do for yourself is move the cursor through every parameter of every screen and hit WINDOW whenever you see it light up. this is more helpful than any video could ever be.

^^ dam straight on that.. Also try pressing shift on the different screens to look for hidden F button options

thank you Nym and golfdogz!
