Thank you for viewing. I am selling this item due to changes in my production environment and relocation. IK Multimedia iRig Keys37 Pro ＜Product Description＞ - 37-key USB MIDI keyboard controller (full-size keys) - Velocity-sensitive - USB bus-powered, plug-and-play (no drivers required) for Mac/PC connection - Equipped with modulation wheel and pitch bend wheel - Octave and program change buttons - Sustain pedal and expression pedal can be connected ＜Condition and Notes＞ - The keys have yellowed overall due to aging, but they are still usable. - A USB cable (not original) that has been tested for functionality will be included. However, it is very short, so it is recommended that you prepare a separate one. - Due to work commitments, shipping may be on weekends.
