A new firmware update is now available for the PSR-SX920 and PSR-SX720.

V1.11 to V1.12
  • Solved an issue of playback Voices when Stop ACMP on Style Setting was set to "Fixed," in which case the Pad and Bass channels were supposed to sound but Piano and Bass sounded instead.
  • Changed the behavior as to whether or not pitch bend affects the Harmony (Vocoder) sound of Vocal Harmony so that it is the same as on PSR-SX900. Operating the pitch bend now affects the Vocoder sound.
  • Fixed other minor problems.
