Waldorf Iridium Desktop MKI 16-Voice Synthesizer w/ OG Box, 128GB microSD + PSU
Couldn't load pickup availability
For sale: Waldorf Iridium MK1 desktop synthesizer in excellent condition with the original box, 128GB microSD card, and power supply. This is a beast of a synth that's a ton of fun to work with. We lost track of time playing with it during testing, which is definitely a good sign.
Details below:
This unit is very nice and clean, near mint condition.
Updated to the latest OS (3.30).
The unit has been meticulously cleaned from top to bottom.
Includes original box and packing materials.
There is a very light abrasion on the right side panel (see photo 24). This unit also has a tiny bit of space between the bottom of the display bezel and the case. At certain angles, a faint bit of backlight exposing the display cable shines through (see photo 25). It is not enough to be bothersome or a concern in our view. This is a common issue with these units, but most sellers do not disclose. Lastly, there is a minor ding in the original box that we patched (see photo 22).
The Waldorf Iridium Desktop is a 16-voice, dual-timbral digital synthesizer and the desktop counterpart to Waldorf's flagship Quantum. Each voice runs three stereo digital oscillators, with five synthesis modes available per oscillator: Wavetable, Waveform, Particle, Resonator, and Kernel. Wavetable is Waldorf's modern take on the morphing waveform technology that traces back to the legendary PPG Wave, with the added ability to generate wavetables from audio. Particle mode is a granular engine. Resonator turns the oscillator into a physical modeling engine capable of string, bar, and membrane sounds. Kernel is the deepest of the five, with up to six internal operators per oscillator running FM, ring mod, and AM at audio rate. Each voice also gets three filters: two in the Dual Filter section running in series, parallel, or a variety of link modes, and a third in the Digital Former, which adds drive, bit crushing, ring modulation, and filter models borrowed from the Waldorf Nave, Largo, and PPG. Six LFOs, six envelopes, a 40-slot mod matrix, and up to five effects slots per patch handle the rest. On top of that, the Iridium adds CV I/O with four inputs routable to the mod matrix, gate and trigger inputs, and analog clock in and out, making it a natural centerpiece in a hybrid setup. A 4x4 RGB pad matrix handles note input, chord triggering, and sequence launching. The color touchscreen is genuinely useful for editing and visualizing what the engine is doing. Up to 7,000 patches can be stored onboard, and patches are fully compatible with the Quantum. It is a serious instrument with a lot of surface area, and it rewards the time you put into it.
Sale includes the synth, original power supply, 128GB microSD card, and the original box and packing.

- Synthesis Type: Fully digital, multi-engine synthesizer descended from Waldorf's flagship Quantum. Five synthesis modes available per oscillator, mixable within a single patch for virtually unlimited tonal range.
- Polyphony: 16-voice polyphony; dual-timbral (split or layered mode) with up to two independent parts.
- Oscillators: 3 stereo digital oscillators per voice, each independently assignable to one of five synthesis engines:
- Wavetable: Waldorf's modern evolution of the PPG Wave morphing technology. Supports wavetable generation from external audio and speech synthesis.
- Waveform: Virtual analog engine with classic shapes, detuning, PWM, hard sync, FM, and ring modulation.
- Particle: Granular engine for textures, time-stretching, and experimental sound design.
- Resonator: Physical modeling engine capable of strings, bars, membranes, and other resonant structures.
- Kernel: Advanced FM/modular engine with up to 6 internal operators per oscillator, supporting FM, ring modulation, and AM at audio rate. Includes macro templates and a low-level editor for deep programming. Compatible with classic FM patch imports.
- Filters: 3 digital filters per voice, fully stereo throughout the signal path:
- Dual Filter: Two filters in series, parallel, or a variety of link modes. Lowpass, bandpass, and highpass modes with 12dB and 24dB slopes. Filter models include Waldorf Nave, Largo, and PPG 3V. Optional saturation and drive.
- Digital Former: Third filter slot with additional processing options including comb filter, bit crusher, drive, and ring modulation, along with filter models from Waldorf Nave, Largo, and PPG.
- Modulation:
- Modulation Matrix: 40 slots, each with one additional control amount. Sources and destinations can be used multiple times until the matrix is full. Modulation can target almost every numerical parameter in the instrument.
- LFOs: 6 LFOs per voice, available in polyphonic and global modes, with MIDI clock sync.
- Envelopes: 6 ADSR envelope generators per voice, freely assignable.
- Komplex Modulator: Waldorf-exclusive hybrid LFO/envelope generator with user-drawable morphable shapes, available as an additional modulation source.
- Effects: Up to 5 effects slots per patch, editable and visualized on the color touchscreen. Available types include chorus, reverb, delay, phaser, flanger, parametric EQ, and compressor.
- Sequencer & Arpeggiator: Built-in step sequencer with up to 32 steps and multiple parameter lanes. Arpeggiator with MIDI clock sync. Both configurable from the touchscreen.
- Performance & Control:
- 4x4 RGB-backlit pressure-sensitive pad matrix for note input, chord triggering, arpeggio and sequence launching.
- High-resolution capacitive color touchscreen for parameter editing, visual feedback, oscilloscope, and spectrum analyzer.
- Dedicated knobs and buttons for most synthesis sections with minimal menu diving. Turning any knob jumps the display to that section.
- Memory: Up to 7,000 patches storable onboard. Patches are fully compatible with the Waldorf Quantum.
- Connectivity:
- Audio: 2 stereo audio outputs (TRS), 2 stereo audio inputs for external signal processing, and a headphone output.
- CV/Gate: 4 CV inputs routable to the mod matrix, Gate In, Trigger In, analog Clock In and Clock Out for Eurorack and modular integration.
- MIDI: DIN MIDI In, Out, Thru. USB MIDI device and USB MIDI host ports.
- Storage: MicroSD card slot for patch and sample storage, plus USB host for data exchange and external MIDI devices.
- Physical Design: Solid metal chassis, rack-compatible desktop form factor. Designed and manufactured in Germany. Industrial-grade components throughout.
