1980's Yamaha KX5 MIDI Controller Keytar (Made in Japan)
Made in Japan by Yamaha in the mid 80's, the KX5 is a 37-note remote MIDI controller with velocity and aftertouch sensitivity. A ribbon controller is used for pitch and mod effects. There's also unison, sustain, portamento buttons and a breath controller input. Up to 64 patches can be accessed via 8 buttons, 4 bank buttons and the sustain button.
Good cosmetic condition for it's age, includes the original strap and case (although the latches are rusted). Previous owner replaced the battery socket with a 9v battery snap, underwent basic testing and seems to be functioning well.
