Based on the legendary multi-engine design of the Quantum and Iridium product line, Waldorf Iridium MK2 innovates even further, fitting perfectly into Waldorf's forward-looking synthesizer design philosophy. Iridium MK2 features a new design and an upgraded CPU board with expanded RAM and flash storage, allowing for greater sample capacity and opening a whole new world of synthesis capabilities.

• 16-voice polyphonic, 4-part multitimbral with advanced modes including round robin and random robin
• 3 oscillators, each capable of 6 synthesis modes: Wavetable, Waveform (virtual analog), Particle (sample playback and granular synthesis), Resonator (physical modeling), Kernels (enhanced FM synthesis), Seeds (enhanced wavetable synthesis incorporating all other oscillator types)
• Dual stereo filters per voice with independent modes: 12/24dB low pass / high pass / band pass, Nave/Largo/PPG/Quantum/StateVariable models
• Digital Former filter models including StateVariable, Raiser, Waldorf Nave, Largo and PPG in high pass, low pass, band pass and notch, comb filters, bitcrusher, various drives, ring modulation, formant filters
• Extensive modulation engine including 6 envelopes, 6 LFOs and Komplex Modulator LFO/envelope combination

• 75mm VESA mount

More memory, more layers
With increased memory, up to 4 multitimbral layers are now possible. In addition to layered and split modes, round-robin and random-robin modes allow the creation of rich, complex sonic landscapes, perfect for sound designers, sonic explorers and cinematic artists.

Seeds: the sixth synthesis sense
Extra RAM enables a sixth synthesis method per oscillator. Inspired by wavetable synthesis, in which each wavetable represents a timbral journey, Waldorf has found a way to base these timbral journeys not only on static waveforms but also to dynamically synthesize each waypoint from sub-oscillators called Seeds.

Flavour knob
Introduced with Waldorf Protein, Flavour adds sonic liveliness via micro-variations in timing, timbre, pitch and other parameters.

Per-note parameter locks
As a special feature resulting from a collaboration with Iridium user Aphex Twin, each of 128 notes can have up to 16 individual parameter variations including the synthesis mode of oscillators and effect parameters. Changes are saved per patch and editable on a dedicated page.
