Watch: Overview video of the Yamaha reface CS Virtual Analog Synthesizer     The Yamaha Reface CS mobile mini keyboard continues the tradition of ground breaking synths like the CS-80. Packed with five types of synthesis and onboard effects, the Reface CS provides you with a variety of lush pads, fat basses, and solo leads. Of course, the reface CS wouldn't be a CS if it didn't give you tons of tweakability, that's why each type of synthesis has its own set of Texture and Mod sliders that take simple oscillator types and let you turn them into gentle soundscapes, mangled sonic carnage, and everything in between. The reface CS features an analog physical modelling engine with multiple synthesis and oscillator with flexible LFO and ADSR routing plus unique texture and mod controls. The synth offers 37 high quality mini keys and an on-board effects processor with five types of effects. 8-note polyphony allows complex chords and pads with the ability to switch to mono mode for fat synth bass or solo leads. USB to host allows MIDI connectivity to a USB-equipped computer or iOS device, with MIDI IN/OUT connectivity via mini-DIN. Dual 1/4 inch unbalanced line outputs and a 3.5mm aux line input allow connection to a wide range of devices. Built-in speakers and battery power ensure inspiration can strike in any place, any time. Ideal for mobile musicians, music creators, keyboardists and sound designers.
