The included damper pedal will function as a half-damper pedal, allowing you to vary the damper effect by how far you press the pedal. If an optional pedal unit (PU-2) is connected, you’ll also be able to use soft and sostenuto pedals in addition to the damper pedal. This gives you three pedals just as on an acoustic piano, and is recommended for the serious piano student or performer.
The SP-280 supports MIDI, the unified standard for transferring performance data between electronic musical instruments and computers. MIDI allows connected devices to control each other, and lets you use the SP-280 as a 16-part multi-timbral sound module.
