Description
Please note this comes from a smoking studio so does have the smell of smoke.
The Roland System-100M 172 is a multifunctional Eurorack-format module originally released as part of the Roland System-100M modular synthesizer in the late 1970s. This module provides three essential modulation effects—phase shifting, audio delay, and LFO modulation—making it a powerful tool for shaping and enhancing analog synth sounds. It is highly sought after for its vintage sound character and deep modulation capabilities.
Functions and Controls
- Phase Shifter: A classic six-stage phase shifter with manual and CV-controlled sweep, providing rich and animated movement to the sound.
- Audio Delay: An analog BBD (bucket-brigade) delay, adding warmth and character to signals, useful for short slapback delays or chorusing effects.
- LFO: A versatile low-frequency oscillator (LFO) with a wide frequency range, capable of modulating both the phase shifter and external modules.
- External CV Control: The CV inputs allow external modulation of phase shift and delay times, expanding its versatility within a modular system.
Sound Characteristics
The phase shifter delivers classic sweeping textures, ranging from subtle movement to deep, resonant phasing. The analog delay produces short, warm repeats, perfect for adding a sense of depth to a synth patch. The LFO can be used internally or externally, making it a valuable modulation source within a larger system.
Country of Manufacture
Japan.
Collectability and Market Value
The Roland System-100M 172 is highly collectible due to its analog warmth, unique modulation features, and integration within the iconic System-100M. Prices for original units remain high, with demand from modular synth enthusiasts and collectors. Many modern reissues and clones attempt to replicate its character, but the original remains a prized module for those seeking authentic Roland 100M modulation effects.
