The PRO-1 brings a beloved single-oscillator analog synth voice into Eurorack format, preserving the punchy, direct tone that made the original a studio favourite. Its dual VCOs and resonant filter deliver everything from fat basslines to cutting leads, and its compact module footprint means it slots easily into an existing modular rig. For Eurorack users who want a proven, musical synth voice rather than another experimental module, the PRO-1 is a dependable choice. Features: Analog synthesizer with dual-VCO design allows for amazingly fat music creation Authentic reproduction of original circuitry with legendary 3340 and 3320 semiconductors Pure analog signal path based on authentic VCO, VCF and VCA designs 3 simultaneous oscillator shapes (OSC A: saw/pulse, OSC B: saw/triangle/pulse waveforms) Classic 4-pole filter design with self-resonance capability Powerful modulation matrix for 2 modulation buses for flexible sound design Dedicated and analog LFO with simultaneous sawtooth, triangle and square oscillator shapes 2 envelope generators for modulation of VCF and VCA Easy-to-use 64-note dual sequencer (LFO clock serves as master clock) Arpeggiator with 3 patterns for great sound effects 16-voice Poly Chain allows multiple synthesizers to be combined for up to 16-voice polyphony Complete Eurorack solution—the main module can be transferred to a standard Eurorack case 56 controls provide direct, real-time access to all important parameters Audio input for processing external sound sources for enhanced creativity External control inputs and outputs (gate, filter) Comprehensive USB/MIDI implementation with MIDI channel and voice priority selection
