Synthesist John L Rice shared this unofficial overview of the Moon Modular M 569 Quad Sequential Voltage Source, a modern step sequencer that builds on the design of the classic Moog 960 Sequential Controller.

The Quad Sequential Voltage Source is an analog step-sequencer with up to 32 positions, arranged in four rows. While the Moog 960 featured three synchronized rows, the Moon M 569 has four rows that are completely independent. That means you can use it as four individual sequencers of different length, or combine them to create sequences of longer lengths. It also adds trigger switches, so you can enable or disable triggers on the fly. And while the Moog sequencer runs left-to-right, the Moon sequencer can run left-to-right, right-to-left, ping-pong and random.

As a result, the Moon Quad Sequential Voltage Source offers the same big knob tactile immediacy of the Moog 960, but lets you create syncopated step sequences and polymetric patterns, with up to four individual patterns.
