Roland System 100 Model 101 Synthesiser

The Roland System 100 Model 101 delivers legendary analog warmth and hands-on control in a classic 1970s monosynth built for creativity and experimentation. With a full 37-note keyboard, rich VCO-driven sound engine, versatile filter and modulation options, and patchable semi-modular design, it remains a coveted instrument among synth purists, vintage collectors, and anyone chasing authentic analogue tone. Ideal for leads, basses, noise FX or modular integration, the 101 is a timeless synth that helped define electronic music’s golden age.

• Fully self-contained analogue mono-synth module with 37-note keyboard and vintage Roland circuitry. 
• Oscillator section includes 1 VCO with pulse-width modulation (PWM), saw and other waveforms, extendable tuning from ~10 Hz to ~10 kHz for everything from deep bass to highest leads. 
• Filter section: resonant VCF (low-pass/high-pass) with ADSR envelope, allowing dynamic filter sweeps and expressive tonal shaping. 
• Envelope & amp control via ADSR (Attack, Decay, Sustain, Release) plus VCA for dynamic sound shaping.
• Built-in noise generator and external “sound-in” input for processing external signals through the synth’s filter and VCA, and useful for experimental or modular-style patching. 
• Semi-modular design: internal signal path ready to play out-of-the-box, yet patchable for keyboard-less expanders or modular rigs.
• Compact vintage form factor. Ideal for both studio racks and live performance setups while retaining classic analog character.
