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.

Inspired by the classic Moog modular synthesizers that came before it, Grandmother's sound engine, modulation engine and onboard 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 Grandmothers 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.

The Grandmother is an awesome value proposition for experimental sound design in a studio environment. It includes the functionality of arguably thousands more $$ in what you'd get from individual modules, and it can sound anywhere from frothing demonic chaos to dreamy ambience (Especially if paired with a good reverb). The most glaring function you miss with the Grandmother is the ability to save presets (Hard to complain at this price). I'm okay with that because I view diving into the Grandmother as an adventure in sound exploration. I take audio snapshots of interesting things I discover (for use later in arrangements), and I don't stay too long in any given place. If I feel like I really need to come back to something, I'll take a photograph and recreate the patch from sight. Most of the time I'm perfectly content to move on and explore some more. If that sounds interesting to you, you'll probably like the Grandmother.
