Using the SD-50 as a MIDI Sound ModuleExplanation of TermsToneOn the SD-50, a “tone” is the unit of sound (e.g., piano, organ, guitar) that you can select. For the available tones, referto PDF “Tone List.”Drum setA “drum set” is a group of percussion instrument sounds. Since percussion instruments are not usually used to play amelody, it’s not necessary that you be able to play different pitches of the instrument from the keyboard. Rather, it’simportant that you be able to use a large number of percussion instrument sounds simultaneously.For this reason, a drum set produces the sound of a different percussion instrument for each key (note number).For the available drum sets, refer to PDF “Tone List.”PartOn the SD-50, a “part” is a unit to which a tone or drum set is assigned.The SD-50 provides sixteen parts, and you can assign a different tone or drum set to each part.EffectAn “effect” refers to processing that can be applied to modify the sound. By switching effects, you can significantlyalter the character of the sound.The SD-50 contains the following effects; you can modify the depth and type of each effect (p. 52).TypeChorusReverbMasteringExplanationAdds depth and spaciousness to the sound.Adds the reverberation that is characteristic of a performance in a hall.Makes the overall sound more consistent and powerful.fig.studio-set_e.epsStudio setA “studio set” is a collection of settings for the sixteen parts and the effects.Studio setPart 16EffectPart 1Tone/Drum setPolyphonyThe number of notes (polyphony) that the SD-50 can produce simultaneously will depend on the tones that areselected. The SD-50’s maximum polyphony is 128 notes, but the actual polyphony will be less depending on thetones you use.If your performance exceeds the maximum polyphony, newly played notes will be given priority, while notes thatwere sounded previously will be turned off one by one.45
