The LinnStrument 128 is a compact expressive MIDI controller featuring 128 multi-touch pads in an 8x16 grid. It provides high-resolution sensing of strike velocity, pressure (Z-axis), left-right movement (X-axis) for pitch, front-back movement (Y-axis) for timbre, and release velocity. It is designed for musicians who seek the expressive capabilities of acoustic instruments in a digital format, with an isomorphic 4ths string layout and support for MPE (MIDI Polyphonic Expression).
