The Lync LN-4 is a 49-note velocity sensitive controller with assignable wheel, switch and control knobs. There’s also a pitch-bend wheel. 4 MIDI outs and switchable channels can tap into 32 MIDI devices! 8 push-buttons can access up to 64 patches as well as increment and decrement. By far the most feature-laden remote keyboard to date (1988; Available in black, white, orange, red, blue and yellow).
This is the famous JHSE version with Jan’s autograph on it.
