Great keyboard. 600 built in sounds and 180 rhythms, 5 song /6 track recorder, not fully weighted but very good touch response. The display shows music notation and other functions. 48 note polyphony and two effects reverb and chorus. It has audio and USB inputs, pedal input and build in speakers. 15.2 lbs. Great for beginners and musicians wanting a grab and go spare. As I am a music teacher, I'm offering a one hour lesson to the purchaser.
