Moog Grandmother

The Moog Grandmother is a semi-modular synthesizer built with the classic feel and true analog sound. Built-in arpeggiator, sequencer and spring reverb tank that is true to Moog’s modular roots, where synthesis is not only about the end result, but the journey of discovery and experimentation.

Grandmother’s semi-modular design ensures that human beings of any skill-level can easily explore and experience the joys and magic of analog synthesis — start playing immediately with “no patching required”, then explore an infinite sonic playground with Grandmother’s endlessly reconfigurable front panel and analog spring reverb tank.

Moog Grandmother’s circuits, spirit, and spring reverb are inspired by the classic Moog Modular Synthesizers designed by Bob Moog during the 60s and 70s. The elegant simplicity and magic of these early circuits are renewed in Grandmother’s semi-modular analog design, resulting in an unrestricted sonic vocabulary that is both beautiful and powerful.

Grandmother also features an “External Audio Input” that invites users to inject sounds from other instruments directly into Grandmother’s analog filter, spring reverb and amplifier circuits — adding vintage tones and ambience to guitars, drums or vocal signals. In addition, Grandmother includes an easy-to-use arpeggiator and sequencer for added enjoyment and programmable syncopation.
