URSA Major Stargate 626 Plugin

When pristine mattered more than character.

Stargate 626 Plugin

A Cleaner Reverb

After creating the SST-282 Space Station in 1978, Christopher Moore set out to solve what he saw as its flaws (now beloved as its signature character): the spectral smearing, modulation noise, and pitch artifacts caused by its wandering delay taps. The result was the Stargate 626 — double the memory for decay times up to 20 seconds, a completely redesigned reverb algorithm with true pitch stability, wider 15kHz bandwidth, and a smoother, more refined character. This plugin faithfully recreates that classic sound with modern conveniences like tempo sync and preset management.

The History of the Stargate

Christopher Moore

Christopher Moore, founder of Ursa Major and Seven Woods Audio.

When the SST-282 Space Station launched in 1978, it was a revelation—a studio-quality digital reverb at a fraction of the cost of competitors like the EMT 250. But Christopher Moore, its creator, was already thinking about what could be improved. The 282's distinctive character came partly from what Moore considered design compromises: the wandering delay taps that caused pitch artifacts, the spectral smearing from its crude modulation algorithm, and the 7kHz bandwidth limitation imposed by the technology of the day.

By 1984, Moore had developed an entirely new approach. Rather than using simple triangle-wave modulation with complementary tap pairs (the 282's method of minimizing pitch wobble), the Stargate 323 employed PROM-based lookup tables with complex, hand-optimized waveforms. More significantly, the Stargate introduced dual-domain modulation—varying not just the delay time of each tap, but its gain as well. The result was true pitch stability and a smoother, more refined reverb character with a wider 15kHz bandwidth.

The Stargate 323 found its way into studios worldwide, prized for recordings where clarity and pristine character mattered more than the 282's distinctive "grit." The Stargate 626 followed, doubling the memory capacity to allow decay times up to 20 seconds and adding six additional programs. This plugin faithfully recreates that algorithm—the signal-adaptive modulation, the PROM-based waveforms, the refined character—bringing the Stargate's sophisticated reverb to your DAW.

SST-206: Complementary Delay Modulation

The Space Station uses 15 feedback taps organized into 7 complementary pairs plus one solo tap. Each pair moves in opposite directions — when one tap shifts forward, its partner shifts back by the same amount. This ingenious design cancels out pitch artifacts while creating the signature dense, shimmering reverb tail. The orb size represents signal level, which remains constant regardless of tap position.

SG-626: Delay + Gain Modulation

The Stargate 626 takes a different approach with its 15 taps. Rather than complementary pairing, each tap modulates independently in both random delay and gain. The ceiling line represents the gain ceiling — a hardware limiter that prevents any tap from exceeding a maximum level. When orbs hit this ceiling, they compress and spark. This creates a smoother, more controlled reverb with less pitch warble but a different character than the Space Station.
