Waldorf’s flagship polyphonic hybrid synthesizer
$4799.99 [note the MK2 version has now been released]
Lately, wavetable synths are all the rage. After Waldorf Music GmbH introduced the Waldorf Quantum synthesizer (and later its nearly equal digital siblings the Iridium Desktop and Iridium Keyboard), a number of synths that incorporate wavetables have been released or announced. These synths can be very nice and some cost significantly less.
From a wavetable perspective, none match the Quantum. Having wavetables does not make a Quantum.
There are no comparable alternatives to a Quantum. There is no room for interpretation of that statement. The Quantum is in a class by itself. Waldorf owns the wavetable hill, period.
In my opinion, the Quantum is as state of the art as it gets even today in 2023. The build quality is tops, and the technology and features are amazing. A new synthesist might want to cut their teeth on something other than a Quantum. It’s not difficult but it is feature rich. That said, the Quantum’s panel and screen together produce a very flat interface, with no menu diving to speak of.
Obviously, no one synth can be everything to everyone, but this comes close. Online video demos tend to over represent the Quantum’s digital side. Sound-wise, the Quantum can do everything from warm virtual analog to crisp digital.
The Quantum has analog filters as well as digital ones. However, if all you want is an analog synth, if you are not looking for the features of a digital synth, the Quantum is not for you.
Wavetables are but one of the five types of synthesis engines in the Quantum.
- Wavetable oscillator
- Waveform oscillator, a more traditional type
- Particle sampler oscillator
- Resonator sampler oscillator
- Kernel oscillator, brand new since OS 2.0, an oscillator construction kit of sorts, way beyond an FM type engine
Your sound palette will be overflowing with options for real. I own a Quantum; if you want a sound universe, this is the one to have.
Yes, it is not inexpensive, but if you think something half its price is comparable, think again. If you are not feeling its value yet, you are not understanding the machine. It is worth the money, period. No snobbery intended. I get it; not everyone can fork out nearly $5k for a synth, but if you can do it without stealing or getting a divorce, consider it.
Rather than reinvent the wheel going into detail of every section, I’m going to point you at the Quantum Tutorials YouTube Playlist below.
Currently the newest ‘official’ firmware release is v2.8.0 which is roughly equivalent to OS 3.0 Beta 12. There is no excuse for running an OS version less than v2.8.0. I would still recommend joining the Beta program (free) and updating to newer Beta versions.
Currently I am running OS 3.0 Beta 15 (Quantum), which is publicly available for Iridium/Quantum by asking Waldorf to add you to the Beta. If you are waiting for the official release of OS 3.0, don’t. OS 3.0 Beta 15 is much more stable, bug free and feature rich. There are also many great patches that require OS 3.0. There is no downside to running the Beta, none. Running OS 2.x.x massively cheats you out of the very best Iridium has to offer. Have I said this clear enough? Ha!
One important thing about Beta OS 15 for Quantum is that it includes the 16 voice digital filter only mode like the Iridium. There are also some mixed 8 analog/8 digital voice modes that are pretty cool.
Personally, I’m fine with 8 analog and/or digitally filtered voices. In actual use I think most people would prefer to have the Quantum’s current 8 analog and/or digitally filtered voices, than 16 digital only filtered voices like the Iridium, but I do think it will be a good to have both options.
The Quantum clearly has value over the Iridium, don’t doubt it for a second. Analog filters, 61 keys, bigger screen, more panel real estate, AUX outputs…
Either way though, get a Quantum or Iridium. Anyone that has or plans on having two or more synthesizers, should have one of these Waldorf synths, period.

I strongly recommended that you run OS 3.0 Beta 15 or newer, unless you hate bug fixes, stability and new features. It is an improvement in all ways over OS 1.x/2.x.

New samples can be recorded from external stereo audio inputs, or from self-recording Quantums own engine.
Samples can also be imported an stored to internal Flash via SD card or USB drive using WAV and AIFF file format (44.1kHz sample rate).
The Quantum allows for a huge range of sample-based sound design capabilities from classical synths sounds to uncharted territories.
It’s worth noting that the sample use in the Quantum is always within a synthesizer’s sonic context, and it is not meant to work as a “bread and butter” sample keyboard to play back like traditional sampling instruments nor third party libraries.
