i've had a love/hate relationship with korg for over 20 years. so i kinda solve that with buying a psr e463. when i get tired of tweaking i go to the yammie. problem solved. this little keyboard does a lot in the right hands. i think thats the key to all keyboard and of this is put the keyboard in the right hands and watch the magic. now i have my both units set up for stage(like thats gonna happen)to use together or alone. at this stage in my life, im very happy with my setup . but im a musician, always ready for change.
