Bastl Instruments Cinnamon Modular System

Bastl Instruments Cinnamon — Voltage-Controlled Filter for Modular Creativity

The Bastl Instruments Cinnamon is a 5HP state variable filter module for Eurorack synthesizers, engineered to provide a wealth of sonic possibilities in a small footprint. For musicians wanting to enrich their patches with subtle warmth or striking character, this module offers a unique set of drive and character switches alongside voltage-controlled cutoff and variable resonance. Expect dramatic changes to filter response and waveform, whether seeking classic or experimental results. Beyond filtering, modular users can explore its VCO and LFO capabilities for expanded functionality.

Versatile Features for Dynamic Sound Shaping

What truly distinguishes the Cinnamon filter are its two dedicated character switches and a drive switch, which enable switching between classic filter curves and harmonically adventurous responses. The character controls influence resonance and waveform, especially when self-oscillating, offering a broad range of sound design. Depending on your settings, the drive circuit can push the filter into smooth overdrive or gritty saturation.

Performance Parameters for Modular Flexibility

Every feature is designed to inspire creativity. The voltage-controlled cutoff frequency lets you sweep and modulate the filter using external CV, while the CV input with attenuator and V/Oct tracking unlock advanced sequencing or keyboard control.

• Module Width: 5HP — fits compact or crowded racks
• Cutoff Control: Voltage-controlled with attenuator for nuanced modulation
• With V/Oct CV input support for melodic and pitch-tracked work, Cinnamon adapts seamlessly to your evolving system.
• Resonance Control: Manual and CV — provides smooth to extreme filter behaviors

Output Variety and Creative Routing

Simultaneous low pass (12dB/oct), band pass (6dB/oct), and high pass (12dB/oct) outputs allow you to split or layer signals inventively. Depending on switch positions, the module can self-oscillate and produce sine, ramp, or saw-like waveforms, catering to unconventional sound sources or modulation shapes.

• Outputs: Low pass, band pass, high pass — all available at once for flexible patching
• Drive Switch: Analog overdrive — adds warmth or bite to any input
• Self-oscillation capability means Cinnamon can act as a sine or saw VCO/LFO when required.

Robust Build, Power, and Integration

Built for reliability, the Cinnamon is protected by a PTC fuse and diode on its 16-pin power connector. At only 35 mm deep, it’s compatible with shallow Eurorack cases and skiffs, drawing less than 30 mA per rail—ideal for dense modular setups. Choose between aluminium or oak wood for the front panel for your preferred aesthetic.

• Depth: 35 mm — fits most Eurorack cases, including shallow skiffs
• Current Draw: +12V: <30 mA, -12V: <30 mA — efficient and safe for large systems
• Available with aluminium or oak wood panels to complement the rest of your modular rig.

For Sound Designers, Performers, and Modular Explorers

Adventurous synthesists will appreciate Cinnamon’s creative control in a compact format. The filter’s topology, flexible drive, and ability to operate as an oscillator or LFO make it perfect for live performance, experimental studios, or compact setups. Each Cinnamon is handmade in Brno, Czech Republic, by Bastl Instruments, reflecting a commitment to quality and modular innovation.
