Matteo,

One of the best ways to learn about your new keyboard is to visit the PSR Tutorial's Lessons Section where you find detailed information on how to use not only the MFD, but all the other functions as well. Nearly all of the instructions for the PSR-2000/2100 also apply to the PSR1500/3000 with some minor differences.

Good Luck,

Gary
