Massive Waldorf Sound in an Ultra-compact Module
The Iridium Core packs the massive sound of Waldorf’s advanced synthesis technology into an ultra-compact desktop module. Perfect for small studios, live performances, and Eurorack integration, the Iridium Core features fewer hands-on controls than its big brother, the Iridium. Still, it retains the three wavetable oscillators (each capable of five synthesis modes), dual stereo filters, ample modulation sources, and power-packed FX section. Plus, the Iridium Core includes the same high-resolution display as the Iridium, giving you easy access to the synth’s numerous parameters. Synthesists at Sweetwater appreciate the Iridium Core’s space-saving form factor and robust build quality. An expertly crafted digital synth module for intrepid sound designers, the Iridium Core is a portal to endless sonic exploration!

Expansive sound generation
With three oscillators capable of operating in five different modes —Wavetable, Waveform, Resonator, Particle Generator, and Kernel Synthesis — the Iridium Core starts the signal chain with a bang! Like the Waldorf Iridium, the Iridium Core features Waldorf's proprietary wavetable oscillator, which produces dramatic, sweeping sound generation. Standard waveforms, such as sawtooth, triangle, and square, are available. Meanwhile, additional waveshaping options, including warp, let you dynamically morph between waveforms. Finally, the Resonator, Particle Generator, and Kernel Synthesis modes push the boundaries of synthesis, providing revolutionary ways for manipulating raw sounds into never-before-heard auditory emanations.


Limitless signal manipulation
The Iridium Core is a sound designer’s dream synth, packed with a slew of powerful modulators. Leveraging its digital topology, the Iridium Core serves up a dual filter, six envelope generators, six LFOs, and a Komplex Modulator, exhibiting a level of precision and flexibility unavailable on other synths. Additionally, the Iridium Core’s Digital Former gives you access to even more modulation tools, including comb filtering, bitcrushing, and ring modulation. Gritty and grimy, clean and surgical — the Iridium Core’s modulators can do it all. Moreover, the Iridium Core empowers you with limitless routing options through its 40-slot Modulation Matrix.
Immersive controls and multi-touch display
To keep the Iridium Core’s footprint as compact as possible, Waldorf limited the number of knobs, buttons, and pads to the essentials. But don’t fear! The Iridium Core’s gorgeous and intuitive high-resolution multi-touch display is designed to keep pace with your creativity. Navigating the Iridium Core’s deep set of functions is highly intuitive. With its user-assignable potentiometers, pads, and macros, you can customize the Iridium Core to fit your workflow, whether you’re in the studio or performing live!
