Harmony/Effect-Related Settings Selecting a DSP type In addition to the Reverb and Chorus effects, a wide variety of DSP (Digital Signal Processor) effects let you enhance the sound, or completely transform it. Some DSP types can be applied only to notes you play on the keyboard while the Reverb and Chorus effects are applied to the entire instrument sound. When you select a Main Voice, the optimum DSP Type for the Voice used is automatically selected. If you want to select a different DSP type, use the procedure described below. NOTE • DSP is an acronym for Digital Signal Processor and it uses a micro processor to change the audio in various ways. 1 Press the [DSP] button to turn the DSP function on. The [DSP] button lights when the DSP is turned on. To turn DSP off, press the [DSP] button again.

NOTE • The volume of the currently playing Voice changes when turning DSP on or off. This is not a malfunction. The amount of change differs depending on the selected Voice. • The DSP type is an overall setting-only one type can be selected. For this reason, when you play a newly loaded Song or Style, for example, the currently playing Voices may not sound as expected. This is normal, since the Song or Style has its own DSP type which replaces any selection you've made before loading. A similar phenomenon occurs when you use the [f], [r] buttons or A-B Repeat function during Song playback.

If you select a different Style without saving, the settings in steps 3 will be cleared. Reference Manual 12
