Grandmother Semi-Modular Analog Keyboard Synthesizer

Back in the day, Moog's modular monsters laid the groundwork for electronic music, and this synth channels that spirit into a desktop powerhouse you can actually play right away. It's got that classic ladder filter growl and a spring reverb tank straight out of the '60s playbook, ready to splash your sounds with vintage ambiance.

At its core, dual analog oscillators deliver selectable waveforms like triangle, saw, and square, with hard sync for ripping leads and thick basses, feeding into a 4-pole ladder low-pass filter (10Hz-20kHz) and a patchable 1-pole high-pass filter for precise sculpting. An ADSR envelope and versatile LFO—stretching into audio rates for FM fun—handle dynamics, while the 32-note Fatar keyboard with pitch/mod wheels, glide, and velocity sensitivity makes it a joy to perform on. Semi-modular design means normalized paths let you jam instantly, but 41 patch points (21 ins, 16 outs, 4-jack mult) unlock wild routing, plus arpeggiator, 256-note sequencer (3 slots), mono audio in, stereo out, headphones, and MIDI/USB connectivity—all in a sturdy 23" x 14.25" x 5.5" wooden cabinet weighing 18 lbs.

Players love its warm Moog tone for basses, ambient drifts, and experimental patches, often calling it a perfect bridge from beginner to modular deep dives. That said, some note the filter cutoff knob can get a touch scratchy over time, though it rarely dims the overall magic.
