The Yamaha KX-5 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. With 2 switchable MIDI channels you can control 2 synths on the fly. None of the buttons or the ribbon control are user-assignable. (1984)
