Grandmother is the latest semi-modular analog synth from Moog. There have been increasingly more and more semi modular synths released in recent years and the demand for rewiring synths and interfacing them with other modular gear grows.

In this clip I explore what’s special about Moog’s Grandmother, and it turns out there’s quite a lot there, especially if you look beneath the surface. For example, while the front panel seems to show only two oscillators and one envelope, in reality, Grandmother has three fully functioning volt/octave oscillators (four if you count the self resonating filter), two and even three envelopes, and is capable of being played paraphonically.

All of these and plenty more patching ideas, tips and tricks are explored in this clip

  1. hi! to play it paraphonic without the help of keystep, it’s possible to to keep the keyboard out into the utilities and send the multiples to the LFO rate and and oscillator 2 pitch? thanks

      Hey – that would just send the same note to all three. You need some external source to generate pitch different than the one generated by the keyboard.

  2. Excellent overview of a great synth! I just unboxed mine & can’t wait to play!
