DOS Days

Sound Blaster Pro (CT1330)

Released in May 1991, the Sound Blaster Pro was the first Creative card to comply with Microsoft's MPC standard. It used a pair of Yamaha YM3812 chips to provide stereo music, although this was rarely used by games. It also added a mixer to provide a crude master volume control, and a high and low pass filter.

It was fully Sound Blaster and Ad Lib compatible, and was the first card from Creative Labs to have a CD-ROM interface on-board. Most Pro cards support only the Panasonic (Matsushita/Panasonic) CD-ROM drives. The Pro is still an 8-bit ISA card, as all the previous Sound Blaster cards are, even though at first glance it looks like a 16-bit card because of the 'AT' section on the connector, but note that these are not wired to anything.

The Pro also got a revised mixer chip which added stereo support. This CT1345 is the middling variant of mixer chip found on Creative cards. It succeeded the CT1335 found on the Sound Blaster 2.0, and was superceded by the CT1745 found on the Sound Blaster 16. It provided 8 levels of software volume control on both left and right channels for Master, Voice, MIDI, CD and Line-In sources, and 4 levels for the Microphone output source. The output mixing path took signals from the Voice, MIDI, CD, Microphone and PC speaker sources.

The DSP chip is CT1341 with DSP version 3.01. The bus interface chip is CT1336.

Competition

In 1991, there was still very little in the way of competition for Creative Labs. The Ad Lib Gold was released this year, and is probably the closest direct competitor to the Sound Blaster Pro.
For those who could afford one, Advanced Gravis launched the UltraSound this year, but while having excellent onboard wavetable capabilities it wasn't backward-compatible with Ad Lib or Sound Blaster, relying on games to be written to directly support it.
If your budget didn't stretch to a Sound Blaster, you would have bought the Ad Lib music synthesizer card instead.
