I have a Lync LN-4 Keytar to sell. You can find it on e-bay. It is in great condition and includes the rack mount power source that has 4 independent midi channels out. Check it out. It plays really nicely and works like a charm. I don't have the instruction manuel, but all of the parts are included and they work great. Also included is the power cord, a midi cord and a really long cord connecting the keytar to the power supply. If you have any questions just let me know. Thanks.
