The Wave Blaster was an add-on MIDI-synthesizer for Creative Sound Blaster 16, Sound Blaster AWE32, and AWE64 family of PC soundcards. It was a sample-based synthesis General MIDI compliant synthesizer. 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. The Wave Blaster's analog stereo-output fed into a dedicated line-in on the SB16, where the onboard-mixer allowed equalization, mixing, and volume adjustment.
The Wave Blaster port was adopted by other sound card manufacturers who produced both daughterboards and soundcards with the expansion-header: Diamond, Ensoniq, Guillemot, Oberheim, Orchid, Roland, TerraTec,Turtle Beach, and Yamaha. The header also appeared on devices such as the Korg NX5R MIDI sound module, the Oberheim MC-1000/MC-2000 keyboards, and the TerraTec Axon AX-100 Guitar-to-MIDI converter.
Since 2000, Wave Blaster-capable sound cards for computers are becoming rare. In 2005, Terratec released a new Wave Blaster daughterboard called the Wave XTable with 16mb of on-board sample memory comprising 500 instruments and 10 drum kits. In 2014, a new compatible card called Dreamblaster S1 was produced by the Belgian company Serdaco. In 2015 that same company released a high end card named Dreamblaster X1, comparable to Yamaha and Roland cards. In 2016 DreamBlaster X2 was released, a board with both waveblaster interface and USB interface.
