 For General MIDI scores, the Wave Blaster's wavetable-engine produced more realistic instrumental music than the SB16's onboard Yamaha-OPL3.The Wave Blaster attached to a SB16 through a 26-pin expansion-header, eliminating the need for extra cabling between the SB16 and the Wave Blaster.The SB16 emulated an MPU-401 UART, giving existing MIDI-software the option to send MIDI-sequences directly to the attached Wave Blaster, instead of driving an external MIDI-device.
