Waldorf Quantum

Waldorf’s flagship polyphonic hybrid synthesizer

$4399.00

Lately, wavetable synths are all the rage. After Waldorf Music GmbH introduced the Quantum, several synths that incorporate wavetables have been released/announced; most notably the UDO Super 6, the ASM Hydrasynth, the Modal Argon8, the Nord Wave 2 and the Sequential Pro 3. These synths are very nice and some cost significantly less. They are however, from a wavetable perspective, less than one-half the machine a Quantum is. Having wavetables does not make a Quantum.

In my opinion, the Quantum is as state of the art as it gets in 2020. 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 analog to crisp digital.

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 in 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 pull $4k out 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.

The Good, the Bad, and the Ugly

To me the Quantum is so unique and so amazing, it is worth a few rough edges. Nonetheless, a consumer should be aware of product characteristics, good and bad. If you are going to buy a new or used Quantum, you should be aware of the common flaws.

In my opinion, the Quantum is more of a studio synth than a gigging or performance synth. It’s big and heavy, which may or may not mean anything to you, but most of all, even OS 2.0 isn’t fully at performance stable yet. OS 2.0 is a huge improvement, wonderful, a joy, rather amazing, but it is still capable of an occasional loud digital pop/bang. A very minor nuisance in a studio synth but unacceptable for a gigging or performance synth.

Hardware issues are a little more important. In the end I chose to send my mid-2019 purchased Quantum in for repair to protect my resale value. The following is quoted from my post 6th month thoughts about the Waldorf Quantum, It is important to note point 1 below is super easy to resolve, point 2 would be easy to ignore and point 3 you probably wouldn’t know if I didn’t tell you.

  1. Squeaky keys – This one is the easiest to fix. You don’t have to tolerate it or take pass on a used machine with the issue. This condition is common to many brands which use Fatar keybeds. The keybed just needs lubrication, check with Waldorf support or your dealer.
  2. Touch screen sensitivity and/or dead zone – Most of the issues with this are firmware design, fixed in OS 2.0. You may notice in the image above, the 6 control areas on the left and right sides of the screen are redesigned to reflect more accurately that there are no buttons for selections like normal and mod; the whole rectangular area is a touch area/button, which once you understand that, makes selection a snap. The middle selector knob between save and previous has been programmed to scroll through selection choices much more accurately and easier than previous touch only selections. You could get a new screen through warranty that is purported to be more sensitive, however the firmware changes make a world of difference and you may not care. Likewise, many Quantums have a dead spot on the right 1/4″ of the screen that can be fixed with a screen firmware update (not to be confused with the OS firmware, this is completely distinct and not currently upgradable from SD or USB. A user upgradable screen firmware may become available in the future, but there is no guarantee at this point). I think most people will not bother to deal with repair of these screen issues since the beta take almost all the pain away. To replace the screen or update the screen firmware, you will need to ship the synth to a warranty center.
  3. Voices with inconsistent resonance – See image above. I wouldn’t have even noticed this if I hadn’t read about it. Thanks to Paul Cotton, who provided these issue confirmation instructions and .wav files: Boot, load a patch > Init the patch > Turn off OSC1 in the OSC MIX (so audio will be just filter self resonance) > Left of the screen, change analog filter 1 cutoff to 67 and resonance to 85.5 , then repeatedly play middle c to cycle the voices. Before fix .wav / After fix .wav To fix this, you will need to ship the synth to a warranty center.

In repair, my Quantum was swapped out for a new one. This Waldorf Quantum rocks. It looks and feels like all $4000 of it should. Be sure to read New Waldorf Quantum Synthesizer is a Beauty for more details.

I want to stress that I believe all currently manufactured Quantums are at this same level of high quality control. I would not hesitate to buy a new Quantum today. Waldorf is a top notch company, I have nothing but high marks for them and the Quantum.

Thanks!

Strongly recommended that you run OS 2.0, unless you hate bug fixes, stability and new features. It is an improvement in all ways over 1.3.0.

Sampling capabilities

Each of the 3 Oscillators of a single timbre can be used in one of three modes using samples:

  • Stereo Multi-Sampler with looping and reverse playback
  • Granular Sampler with extensive parameter set
  • Resonator model using sampler as exciter

Samples are organized using key and velocity maps, selections rules like round robin, random etc., and individual pitch, gain and pan settings.
Samples are stored in internal Flash memory of about 4GB capacity pre-filled with over 1GB specially made for Quantum factory samples.
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.

Huge range of arpeggiator parameters:

  • 7 Algorithms to choose from like up, down, random etc.
  • Octave range
  • 7 Sort Orders
  • 3 Velocity Modes
  • Gate length
  • Swing
  • BPM
