Using the SD-50 as a MIDI Sound Module
Tone
On the SD-50, a “tone” is the unit of sound (e.g., piano, organ, guitar) that you can select. For the available tones, refer
to PDF “Tone List.”
Drum set
A “drum set” is a group of percussion instrument sounds. Since percussion instruments are not usually used to play a
melody, it’s not necessary that you be able to play different pitches of the instrument from the keyboard. Rather, it’s
important 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.”
Part
On 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.
Effect
An “effect” refers to processing that can be applied to modify the sound. By switching effects, you can significantly
alter the character of the sound.
The SD-50 contains the following effects; you can modify the depth and type of each effect (p. 52).
Studio set
A “studio set” is a collection of settings for the sixteen parts and the effects.

The number of notes (polyphony) that the SD-50 can produce simultaneously will depend on the tones that are
selected. The SD-50’s maximum polyphony is 128 notes, but the actual polyphony will be less depending on the
tones you use.
If your performance exceeds the maximum polyphony, newly played notes will be given priority, while notes that
were sounded previously will be turned off one by one.
