The Edirol PCR-M30 32-Key MIDI Controller offers direct connection to your computer through USB. Edirol gives you 32 keys, 27 assignable MIDI controllers, MIDI I/O, and both sustain and expression pedal connections with the PCR-M30. Edirol also includes a software editor with the PCR-M30 MIDI Controller. The PCR-M30 controller adds features like velocity curves, a switchable MIDI interface, V-LINK, and key action from Roland's higher-end synths. The assignable control array includes 8 knobs, 8 sliders, 9 switches, and 2 pedal ports. The key action has been refined to produce even less mechanical noise than its predecessor and to offer a consistent, playable feel. The keys themselves are slightly more rounded to keep your fingers from tripping over the keys during quick glissandi. The Pitchbend/Modulation has a rubber coating for easier grip.
