Selecting Sounds
The SP1 organizes its 16 presets into four main categories: Piano, Keyboards, Strings/Pads, and Other.

Using Effects (FX)
The SP1 includes four individually adjustable effects.

The transpose function allows you to shift the pitch of the entire keyboard up or down in semitone steps.
