Model-15

EurorackAnalogMonophonic

Inspired by the legendary Moog Model 15 modular from the 1970s, this semi-modular beast delivers that classic east coast analog warmth in a compact Eurorack footprint you can pop into your case or use standalone on the desktop. It's like having a slice of synthesizer history that's ready to play out of the box, no patching required, but with tons of expandability for deeper dives.

Dual VCOs offer four waveforms each, oscillator sync, pulse-width modulation, and a sub-oscillator for crafting thick detuned basses or searing leads, shaped by the iconic 24dB low-pass ladder filter with resonance, plus a high-pass filter and noise source. Modulation comes from an analog LFO with four waveforms for pitch, filter cutoff, and PWM, paired with a snappy ADSR envelope generator. Onboard goodies include a 256-step sequencer with three memory slots, key transpose, and multiple modes; an arpeggiator with hold; and spring reverb emulation for vintage space. Forty-eight patch points on a dedicated matrix let you reroute signals or integrate Eurorack gear, while 37 hands-on knobs and switches give immediate control—audio in/out, headphone jack, full MIDI DIN/USB (in/out/thru), CV/gate, and 16-voice poly chain capability seal the deal in its 80HP powered enclosure.

Players love its authentic Moog-like tones at a fraction of the cost, praising the fat sound and sequencer for live performance, though some note the lack of portamento as a minor tweak you'd add modular-style. It's a gateway to modular without the overwhelm, perfect for vintage vibes in modern setups.
