The PSR-S670 from Yamaha is a more entry-level arranger workstation that combines a wide range of sounds together with powerful performance features. Covering a multitude of styles, the keyboard brings the experience of performing in a band to the solo keyboard player. Two assignable live controllers, a modulation wheel and two assignable foot-pedal inputs ensure total control over voices, styles, effects, and other functions during live performance.

A new DJ Styles concept features a collection of chord progressions that eliminate the need for continuous chord changes with the left hand. And to enhance practicing and performance, Yamaha Chord Tracker app for iPhone and iPad (sold separately) instantly identifies and extracts any chord sequence from an audio track stored on the keyboard. Sound expansion is available using the on-board expansion memory.

Audio data can be played back using the USB Audio Player, or triggered using the Audio Link Multi-Pad function, providing even more creative options. The unit also has an auxiliary input jack to connect an audio player, and a dedicated line output that makes it easy to use the keyboard with a PA system or audio interface.
