This monophonic synthesizer became a favorite among electronic musicians seeking powerful bass, growling tones, and experimental sound design options.
Sound Generation
- Type: Analog modular synthesizer
- Sound Characteristics:
- Rich, punchy bass sounds and growling tones
- Capable of producing “blippy” effects and experimental textures
- Integrated phaser effect for thickening lead sounds
Features
- Modules: The system included a variety of modules for sound design, such as:
- 3 VCOs: Voltage-controlled oscillators for generating rich analog tones
- VCF: Voltage-controlled filter for shaping frequencies
- VCA: Voltage-controlled amplifier for dynamic control
- LFO: Low-frequency oscillator for modulation effects
- ADSR Envelopes: Punchy attack-decay-sustain-release envelopes for precise sound shaping
- Phaser Effect: Built-in phaser for adding depth and movement to sounds
- External Processing: Features three audio inputs to process external sounds through its filters and modules
- Keyboard Control: A remote 61-note keyboard controlled the system via CV/Gate (no MIDI support)
Connectivity
- Patching: Extensive modular patching options for creating complex signal paths
- Audio Inputs/Outputs: Multiple inputs and outputs for integrating external audio sources and processing them through the system’s modules
Legacy
The RSF Modular Model 11 is celebrated for its unique sound and versatility. It was used by notable musicians such as Klaus Schulze, who incorporated it into his live rig alongside Moog systems. Its advanced sequencing capabilities allowed for intricate patterns and creative sound design, making it a powerful tool in the hands of skilled users.
The system’s rarity and high cost (approximately DM 8,000 at the time, equivalent to £15,000 today) limited its production, making it a sought-after collector’s item in the vintage synthesizer market. Despite its limited availability, the RSF Modular Model 11 remains an important piece of synthesizer history.
