Citadel Alchemist

Bastl Instruments Citadel: The Runic Powerhouse for Eurorack

The Bastl Instruments Citadel translates the esoteric sonic soul of the Kastle Alchemist into a high-performance Eurorack module. Built around a sophisticated 'Runic' synthesis engine, this digital oscillator excels at producing harmonically rich textures, liquid-metal FM tones, and organic digital chaos. With dedicated CV inputs for every parameter, the Citadel can shift seamlessly from serene, glassy drones to aggressive rhythmic pulses. Whether you are hunting for pristine wavetables or crushed lo-fi noise, the Citadel serves as a mystical cornerstone for any experimental modular system.

Key Features:

• Runic Synthesis Engine: Features multiple distinct algorithms that blend complex wavetable scanning with unique digital grit.

• Comprehensive CV Connectivity: Full external control over pitch, timbre, and wavefolding for highly expressive patches.

• Integrated VCA & Decay: Features an onboard mini-envelope, allowing for self-contained percussive sounds and plucks.

• Character Clipping: Includes digital saturation modes that add warmth and harmonic weight to the output.

• Efficient Footprint: Packs a massive sonic range into a slim width, perfect for compact or crowded performance cases.

Technical Specifications:
