No Sound in a Specific

Range

With certain Tones, for example Rhythm Sets, bass Tones, Timpani, and other Tones will
not sound if a portion of the Tone falls outside the recommended range.

Not All Sounds Are

Played

The RD-300GX has a maximum polyphony of 128 voices. When playing together with a
song or Rhythm along with heavy use of the damper pedal, the performance data may
exceed the number of available voices, and as a result, some notes or sounds played on
the keyboard may not sound.

Not all keyboard

performance data could

be processed

Could you be playing back an MP3 file, or changing the playback tempo of an audio file?
The following measures may solve the problem.
• Use WAV/AIFF format data rather than MP3 format data
• Return the song tempo to its original setting (to 0%)
