Danny, what Rikki says is true ... When I last needed a key replaced on my Kn6000 it took a while for me to find a technician ...
Donny (Dnj) has said the Kn5000 was one of his favorite boards ...
Kn5000 was ahead of it's time great arranger kb
I disagree.... Both the Korg i30 and Roland G1000 were miles ahead on stage and in sales..
Features and advanced controls left the KN5000 way behind.
Things like hard drives and zip drives, touch screen and chord sequencer. Key feel. etc.
