Waldorf Iridium Core is a Compact version for performers and musicians on the move

Today, Waldorf has introduced the Iridium Core, a compact synthesizer that they say puts the full Iridium synth engine into a compact desktop synth with 12-voice polyphony.

Waldorf’s Iridium synth began life as a desktop module, then turned into a keyboard, and has now risen in a desktop format once again. Known as Iridium Core, this new 12-voice version contains the full Iridium sound engine, and enables you to access it via a supposedly easy-to-use interface.

The Iridium Core is compact enough to fit into laptop bags and in carry-on luggage, but still features 5 synthesis engines: Wavetable, Multi- & Granular-Sampling, Waveform, Kernel FM and Resonator. Combined with a broad selection of digital filter and processing options, Iridium Core lets you explore a huge range of electronic sound.

Why the need for it, though? “Many performing musicians have asked us for a more compact and portable form factor for the incredible Iridium sound engine to pack into their travel bags or allow already densely-packed studio environments to more easily accommodate another hardware instrument,” explains Waldorf Music CTO Rolf Wöhrmann.

“Inspired by their feedback, we came up with the Iridium Core concept, and are very proud of the finished result,” he adds. “Indeed, it’s a thing of beauty, ready to be taken anywhere, and we can’t wait to hear all the music made with Iridium Core!”

Iridium Core shares the same software platform as Quantum, Iridium Desktop & Iridium Keyboard. All instruments are powered by the Waldorf synthesizer OS and will receive joint updates.

Iridium engine features three oscillators, five synthesis models (wavetable, multisample/granular, waveform, resonator and kernel), filters, a 40-slot mod matrix with LFOs and envelopes, effects, an audio recorder and more. As on previous iterations of the synth, these features can be accessed from a combination of a touchscreen, buttons and knobs.

These controls include six assignable macro buttons for performance control, and four user-definable knobs that work on either a patch or global basis. There are 1,700 factory presets, and patch compatibility with not only the other members of the Iridium family, but also Waldorf’s Quantum and Quantum MK2.

Connectivity includes mini-jack MIDI I/O, CV, Clock, audio I/O and a MicroSD slot.
