IK Multimedia 148194 iRig Keys 37 PRO MIDI Controller

The IK Multimedia iRig Keys 37 PRO is a USB MIDI controller designed for musicians and producers who want full-sized key action without the bulk of a 49- or 61-key board. Its 37 velocity-sensitive keys respond to playing dynamics, translating soft touches into quiet notes and firm strikes into louder ones — a crucial feature for realistic piano, organ, and synth performances that mini-key controllers often struggle to deliver. Flanking the keyboard are dedicated pitch bend and modulation wheels, giving performers real-time expressive control that many compact controllers omit or relegate to touchstrips and buttons.

Beyond the keys, the iRig Keys 37 PRO keeps things deliberately simple. A single assignable knob handles volume, data entry, or any MIDI CC parameter you map to it, and backlit octave/program up-down buttons let you shift the playing range or step through patches without reaching for your mouse. The SET button stores and recalls custom configurations, which is useful if you switch between different virtual instruments or DAW setups. The entire unit is USB bus-powered and class-compliant, meaning it works out of the box on Mac and PC with no driver installation and no external power supply. For producers building a portable rig or keyboardists who need a practice controller that still feels like a real instrument, the iRig Keys 37 PRO strikes a practical balance between playability and portability.
