Roger Linn Design LinnStrument USB MIDI Controller

Gently used condition, includes powered USB cable, carrying bag and paperwork.

From Roger Linn:

Works with every MIDI synth.
LinnStrument sends standard MIDI messages over its USB or MIDI output jacks, and is configured by default to work out-of-the-box over a single MIDI channel for compatibility with every MIDI sound generator in existence, but with the advantages over a MIDI keyboard of performed vibrato, note-to-note pitch slides, polyphonic pressure sensing, and forward/backward touch control. And LinnStrument gets around MIDI's one-channel Pitch Bend limitations by automatically quantizing polyphonic pitch slides to semitones, while leaving solo pitch slides continuous.

To also perform fully polyphonic pitch slides and Y-axis gestures, you'll need a synth that's compatible with MPE (MIDI Polyphonic Expression), a new MIDI standard that uses a separate MIDI channel for each touch. It's already supported in a long list of major software and hardware instruments. We even include free sound files for Apple's MainStage and Logic, plus a free license for Bitwig 8-Track, all of which support MPE in their built-in synths.
