The Waldorf Iridium at a glance
The IRIDIUM keyboard is based on the highly acclaimed desktop version and is in no way inferior to it in terms of sound. In addition, both versions are a modification of the exceptional QUANTUM synthesizer, which can certainly be considered a milestone in the history of synthesizers. In the case of the IRIDIUM, modification means that the instrument boasts an impressive 16 voices and outstanding digital Multimode filters. Keyboard enthusiasts can look forward to the high-quality49-key FATAR keyboard with polyphonic aftertouch and velocity response. The keyboard version does without the 16 pads of the desktop unit, but the area to the left of the keyboard has been considerably extended, which more than lives up to the term "performance section". Eight control voltage inputs and outputs on the rear panel allow the IRIDIUM to be controlled with components of a Eurorack modular system or semi-modular synthesizer.
Synthesis
At the heart of the Iridium are its three digital oscillators, each with five selectable synthesis modes:
Wavetable: Waldorfstyle with the latest Nave technology including voice synthesis and generation of Wavetables from external audio sources
Waveform: Waveform with up to 8 simultaneous waveforms per oscillator in detuned or chordal mode with hard sync, warp, PWM and pitchable noise
Particle: Granular sampler with multi-sampling and traditional sampling mode
Resonator: Exciter with multi-sampling and filter bank modeling
Kernel: a meticulously structured tool for creating futuristic experimental sounds and FM-like sounds
Some of the oscillators are incredible in their own right and offer an enormous range of different sounds. As there are even more parameters under the hood, which can also be modulated at various times, new sound creations are likely to be an ongoing process in the best sense of the word. The Iridium's filter is an excellent, dual Multimode filter of digital origin and covers a wide spectrum of resonant and muted sounds. The elaborate signal chain is completed by five simultaneously available effects such as delay, reverb, chorus, Flanger or Phaser and the Master compressor.
Modulation
With six loopable envelopes and LFOs each as well as the complex modulator, which is a mixture of two LFOs with waveforms and an envelope that you can draw yourself(!), you have enough options at hand alongside the usual modulation sources such as eg. Velocity or Aftertouch to fill the 40-entry modulation matrix and thus breathe life into the sound at almost any point.
Access
The high-resolution multi-touch display allows convenient access to every parameter and visually implements every action on the control panel. With impressive precision, it shows real-time changes in the sound at various stages of the synthesis process. It is the same size as that of the Quantum and is surrounded by the same set of knobs and buttons.
Sequencer, arpeggiator, chord & macros
To the left of the keyboard is the so-called performance section; in addition to tried and tested standards such as the octave selection and the two handwheels for Pitchbend and modulation as well as the hold button (latch), there are some direct access options here. Mono switches between monophonic and polyphonic play for the current patch. Chord allows you to create a chord. Seq/Arp takes you directly to the appropriate menu page on the touchscreen and switches between sequencer and arpeggiator when pressed again. The six self-definable macros are a great help when using the IRIDIUM keyboard as you can define which function you want to access most quickly and which action you want to perform. For example, you can jump directly to the recording section of the sequencer or switch glide on/off.
