Waldorf Iridium has made the impossible possible. The mighty synth engine from Quantum is now available in a compact form. Tracing the footsteps of its bigger brother, Iridium features all the synthesis elements of Quantum as well in a rack-compatible format. The combination of the powerful engine, incredible flexibility and detailed sound shaping facilities creates sheer endless possibilities of sound. Yet, the comprehensive layout and easy-to-understand structure lets you design your own sounds in no time. Sporting a solid metal casing and the same high level of craftsmanship like Quantum, Iridium is now ready to take over studios and stages throughout the world.
 
Contributing another entry in Waldorf's rich history, Iridium joins the family as a direct descendant of the PPG Wave. Though, Iridium offers much more than its ancestor. Five different synthesis models are provided by Iridium for each of the three oscillators:
Wavetable
Waveform (Virtual Analog)
Particle (Sampling and Granular Sampling)
Resonator
Kernels

Kernel mode has been introduced with the OS 2.0 of Quantum. This huge upgrade allows one oscillator to be turned into up to six sub oscillators. These can be interlinked through FM at audio rate and arranged in user-definable constellations. Just this upgrade alone would have provided enough additional features to create a synthesizer on its own. Now, all those functions have been integrated into Iridium as well.
Up to 7000 patches can be saved in Iridium. Patches from Quantum can be loaded in Iridium and vice-versa.
Iridium features three digital filters per voice. Two in the Dual Filter section and another one in the Digital Former. Several types are available to choose from:
12 or 24dB and Lowpass/Highpass/Bandpass with optional saturation or dirtiness.
Various filter models are available including those from Waldorf Nave, Largo and PPG 3V.
The Dual Filter section can be controlled independently or together in several different link modes.
The Digital Former offers all the filter types and models from the Dual Filter plus unusual models like Comb, Drive, Bitcrusher and more in addition.

All filters retain a true stereo signal throughout the entire structure of the instrument.
Up and down, back and forth
6 Envelopes, 6 LFOs and many more are just waiting for being used as sources in the 40 slots of the Modulation Matrix. Each slot has one additional control amount. Modulations can be directed to almost every numerical value in Iridium. All sources and destinations can be used as many times as desired until the Modulation Matrix is full. If you ever happen to run out of LFOs or Envelopes, you can use the Komplex Modulator for generating a custom shape LFO or Envelope.
