Regarding the oscillators, the Grandmother has two, each with a variety of waveforms. The oscillators can be synced and detuned from another for more tonal possibilities.
The Matriarch’s oscillators are similar to the Grandmother’s, but its modern equivalent has four of them. All of the oscillators can be synced together, and also have frequency and pulse width modulation inputs.
For the Moog Grandmother, the filter is a 24 DB/octave ladder-style filter with a classic Moog sound. It also has the option for keyboard tracking.
The filter section on Matriarch is again similar to Grandmother, but it has two ladder filters. They can be run in series, parallel, or stereo, making the filter very versatile.
The Grandmother’s 256-step sequencer also has an arpeggiator, and can play back a sequence forwards or in reverse. The Matriarch also has a step sequencer with 256 steps, but it can also save up to 12 sequences in its memory for playback.
Modulation with the Grandmother is provided by an LFO that is routed for pitch and filter modulation but can also be assigned elsewhere via the patch bay. It also has a sample and hold output for additional random modulation.
