FEATURES Easy Installation All you need to do is to mount the SCB-55 onto a sound card compatible with Sound Blaster, and you can enjoy high-quality sounds with music or game software. 16-part Multi-Timbral Sound Generator The SCB-55 is a 16-part multi-timbral (including the drum part) sound generator.
