ADJUSTING THE POLYPHONY/TEXTURE

The Concertmate 690 lets you adjust the polyphony and texture of its sound.

Note: “Polyphony” refers to the level of harmony and the number of notes played to produce the sound. “Texture” refers to the sound’s quality or depth.

Your Concertmate 690 is automatically set to high-level polyphony/texture ev- ery time you turn it on and begin play- ing.

To switch to low-level polyphony/tex- ture at any time during play, simply press SOUND POLY/TEXTURE. To switch back to high-level polyphony/ texture, press it again.
