SMK-37 PRO

A built-in DX7-style FM engine turns this wireless MIDI keyboard into a portable instrument. Its 37 velocity-sensitive keys and 16 RGB pads with velocity and aftertouch support offer separate surfaces for melodic playing and rhythmic control. A sequencer records in steps or real time, supports up to 64 steps, and saves eight patterns alongside arpeggiator, note-repeat, scale and chord functions.

The sound engine offers 32 FM algorithms, adjustable feedback and mono or polyphonic operation. A low-pass filter, distortion, reverb and delay shape the sound, while four preset banks can receive custom patches through USB MIDI. Eight endless encoders, four bank-switchable faders, pitch and modulation wheels, and a 1.54-inch display provide hands-on control.

USB-C and Bluetooth MIDI connect to computers and mobile devices, with a separate 3.5 mm MIDI output for external hardware. The 3.5 mm audio output supports headphones or audio equipment, and the quarter-inch pedal connection can operate as sustain or expression. A 2,000 mAh rechargeable battery is rated for up to 10 hours; the keyboard measures 458 x 181 x 50 mm and weighs 1.1 kg.
