Rediscover the raw power of classic analog monosynths with a build-it-yourself twist that elevates the iconic Sequential Pro-One design. The PRO2021 MKII delivers monophonic subtractive synthesis through dual Curtis CEM3340 VCOs, a lowpass filter with Alfa CEM clones, dual envelopes, and a single LFO, all enhanced by the Music Technologies Group Turbo CPU for superior control and sequencing.
Crafted for DIY enthusiasts, this keyboard-format synth skips hand wiring with improved PCB layouts for lower noise, premium metal-shaft pots, high-quality switches, and a robust metal panel. Its Fatar keyboard offers monophonic aftertouch tied to filter and pitch modulation, plus full DIN MIDI In/Out/Thru and USB ports for seamless integration.
Unleash thick basses, searing leads, and rhythmic sequences with pro-grade components like machined aluminum pitch/mod wheels and cherry wood cheeks—ready for your custom finish. In production since 2025, it's the ultimate Pro-One clone you'll build and play for years.
