Moog Grandmother

Semi-modulator analog synthesizer (2018)

Grandmother is a semi-modular analog synthesizer with a built-in arpeggiator, sequencer and spring reverb tank, evolution of previous MOTHER then followed by MATRIACH

OVERVIEW 32 Full-Size Keys Velocity-sensing (from Fa to C two octaves above with octave switch) and regular wheel pitch and modulation. .Very colored synth with different section! The patchbay is very interesting for modular purpose: there are 21 IN + 16 OUT .

Terminal connectors:

Audio Inputs: 1 x 1/4" (instrument in), 1 x 1/8" (reverb in)

Audio Outputs: 1 x 1/4" (main/headphones), 1 x 1/8" (reverb out), 1 x 1/8" (eurorack out)
Headphones: Shared with main out
USB: 1 x Type B
MIDI I/O: In/Out/Thru/USB
Other I/O: Clock in, Clock out, Reset in, On/Off in, 41 x Patch Points
Power Supply: 12V DC 2A power supply (included)

OSCILLATORS The structure includes two analog oscillators (from 32 'to 2') inspired by those of the Model D but a bit less powerful (it's a budget synth), with triangular, ramp, square, pulse waveforms, hard sync support between osc 1 and 2, linear FM management and remote PWM control

ENVELOPE 1 EG x ADSR - a single envelope is just a shame.

EFFECTS For some weird reason I cannot understand, a cheap spring tank has been added as an effects. External sounds can be processed

SEQUENCER/ARPEGGIATOR you can save up to three sequences in the Grandmother sequencer, each of which can be up to 256 steps in length

MEMORY no presets memories
