Featuring a 37-key design, 128-note polyphony and five distinct organ waves from American tonewheel to British transistor, the Yamaha Reface YC Mobile Mini Keyboard brings accurate organ emulation into the 21st century in a sleek, shiny package. Able to capture an even wider range of tones through the onboard nine drawbars and four traditional organ tones, this little beauty can go from a Sunday gospel wail to moody '60s psychedelia with a few twists of the knob.
