KN 5000 5-6 octaves, I'm not sure ... trs I do not know the rponses your questions, I do not know many functions of the keyboard. There are many things to do with, full of sound and style of music, DMOS prenregistr I really like and all sorts of effects.

UTILIZATION

Difficult, I have no manual I bought it second hand ... Do you have a manual?? There is a kind of aid recorded in the memory, it's a good idea and a good tool to be dpann.

OVERALL OPINION

For about 2 years ~ ~ I love karaoke and the keyboard with all these functions. ~ I do not Chagas, I love it. I have not tried other models before. I had a real piano before, but we pass the fire and too expensive c'tait a real piano, and we found that KN 5000 second hand, it's for a we have now.
