Very easy to comprehend, but the sounds are not editable.
Keyboard bought us in 1995 for $700 as a first keyboard. I did some gigs with it in small groups and it always been of precious help. I would like to stress here the quality of this gear sounds damn good even when. The sounds are very good, especially the piano sounds that are difficult to match even with more expensive devices. For me it's a keyboard with a more sentimental value. It has always been of precious help.
