With a stunning design, new voices and styles and DJ functions, the PSR-S670 is a performance keyboard like no other. Real-time control knobs, assignable pedals and expansion ROM make it customizable for your needs. Wireless audio and MIDI are possible over Wi-Fi using Yamaha's UD-WL01 USB wireless LAN adapter and compatible iOS apps. Easily assign the control knobs to a variety of different functions, such as cutoff and resonance, reverb and chorus and much more. Once you've assigned the functions to the knobs, simply turn them to add expression and effect to styles and voices in real time. DJ Styles are a new live performance concept featuring a collection of programmed chord progressions. This leaves both hands free to play melody lines, use the live controllers or even trigger additional audio samples with the multi-pad. With the new arpeggio function, PSR-S670 will play the phrase for you while you simply hold the chord.
