Moog Grandmother Analog Keyboard Synthesizer

Semi-modular design and real spring reverb make the Grandmother a powerful analog synth, handmade in NC by the pioneering, one-and-only Moog Music company.
Grandmother is a sonic playground that harkens back to Moog's modular roots, where synthesis is not only about the end result, but the journey of discovery and experimentation. While capable of highly complex sounds and modulation, Grandmother's semi-modular design requires absolutely no patching, ensuring that human beings of any skill-level can easily explore and experience the joys and magic of analog synthesis.

Dive into the Moog Grandmother:

Inspired by the classic Moog modular synthesizers that came before it, Grandmother's sound engine, modulation engine and on-board spring reverb tank are completely analog, resulting in an unrestricted sonic vocabulary of immeasurable beauty and power. In addition, Grandmother also features an easy-to-use Arpeggiator and Sequencer for added enjoyment and programmable syncopation.

Though not required, creative patching and exploration are the keys to discovering exciting new relationships between modules and to truly unlocking Grandmother's infinite expanse of auditory inspiration. Patching can also be used to override internal connections, allowing each section to function just as an independent module would.

In addition to its standalone function, Grandmother is also an ideal analog audio processor for external sound sources, and a powerful keyboard front end for expanding a Mother-32, DFAM or Eurorack modular system.

"Moog Grandmother is an amazing synth!"
Verified Customer zZounds has verified that this reviewer made a purchase from us.
This synth really is awesome and has so many sonic capabilities. I typically control notes and tempo via midi through my DAW (as master) since I am not a great keyboard player (yet!) plus it gives me a wider range of notes to experiment with. Creating interesting and usable sounds have been insanely fun and really puts me in a trance sometimes when I dim the lights and get in the zone. Low or high frequencies sounds very pure and clean. The spring reverb is nice, but for the sounds I like to make I have been using Eventide Space and TimeFactor pedals with the Grandmother and I just love everything that comes out of this synth. It's pretty much impossible to make a bad sound. One of my best musical purchases in a while.
Musical Background:
I'm more interested in sound design at the moment rather than producing music.
Musical Style:
Electronic, Ambient, Downtempo
