I’m a big fan of Tangerine Dream and owning a Waldorf Quantum gave me the opportunity to use a wavetable synthesiser ( as well as waveform, particle and granular synthesis) and try and emulate PPG-type sounds with hardware. I will,use this to make Berlin School music for my personal pleasure and for short film soundtracks etc.

This is a solidly built (pressed steel) LED-emblazoned thing of beauty. Even the pitch and expression wheel are metallic! Viewing it in subdued lighting transports me (pun intended) to,the bridge of a SciFi flight deck: It’s thrilling. The keyboard has a nice positive feel. It’s a very heavy device which again lends it a feeling of quality. On powering it up, I updated the firmware as suggested before delving into the sounds.

Most of the patches are....harsh, digital, abrasive sounds perfect for soundtracks and scaring ones underwear off at night! There are a few bell-like ringing sounds but there are no really smooth string-like pads which is a great shame. To be honest I feel these patches were developed to show off the extreme sounds the Quantum is capable of producing rather than acting as starting points from where one can develop usable sounds. Slime will like that, others will find it tiresome.

I have experienced some software glitches such as screen going white, clicks and buzzes when standing idle, expression being stuck in the on position all of which required the Quantum to be rebooted.

The user manual is pretty useless and I rely on the Waldorf forum members for help. They are a great resource, helpful and SO knowledgable .

In conclusion the Quantum has military-standard construction, a temperamental firmware, digitally harsh sounds (use Youtube to hear some of the patches), but the vast flexibility means I’m going to have years of fun developing sounds and exploring its capabilities.


The only limitation is your own imagination.

You can read in-depth profession reviews of the Quantum by typing a search into Google. They all, without exception, shower praise and adulation on this incredible synth, destined to become a future classic.

In my opinion this is a synth for those with imagination, who want to abandon the presets of others to create, conceive and invent their own sounds and auditory landscapes. You will also need knowledge, patience and an inquisitive mind to spend time with the Quantum, as there is a direct correlation between the time invested and the quality of the result that you achieve.

For me the Quantum provides a perfect interface to my sonic imagination that does not set limitations. The synth looks absolutely beautiful, the layout is very well thought out, the build quality second to none (it's a Waldorf) and the screen is an absolute delight to use.

25 stars somehow doesn't seem enough. Thank you Waldorf Music!

Prachtexemplar von Synthesizer
Till aus T. 08.10.2018
Der Quantum ist ein Synthesizer aus guten Hause und ist weit mehr als ein Nave App oder VSTi in Hardware. Durch die verschiedenen Betriebsarten der Oszillatoren (jeder seperat auswählbar), die jeweils doppelten analogen Tiefpassfilter und die bekannten digitalen Filter aus den letzten digitalen Waldorf Plug-Ins, NaveApp bzw. Q.
Es wurde mal nicht gespart an LFOs und Envelopes. Die Modmatrix bietet viele Quellen und noch mehr Modulationziele.
Mit dem farbigen Touchdisplay wird die Bedienung zusätzlich zu den über 70 Drehknöpfen noch mächtig erweitert. Der Quantum ist nicht nur zum Presets abrufen, sondern er will befummelt werden. Klänge editiert, externe Samples in Granularsynthese verwendet werden, oder Samples zu Wavetable resynthesiert werden.

Der Klang ist durch die vielen Möglichkeiten der Oszillatoren, selten gab es in einer Oszillatorsektion so viele Möglichkeiten. Und mit einem Regler kann ein VA Oszillator gleich nach einer ganzen Bank von bis zu 8 Oszillatoren klingen. Wavetable Synthese hat mit dem Spectrum-Parameter vom Nave eine zusätzliche klangliche Dimension erhalten. So kann man aus den bekannten klassischen Waldorf-Wavetables immer wieder was neues rausholen. Die Granular-Synthese (mit dem Sample-Player) und die Resonator-Funktion müssen erst noch ausgiebig entdeckt werden. Dann die vielen Möglichkeiten der Filterkombinationen. Es kann also nicht so was wie DEN Quantum Grundklang geben. Da gibt es weiche Pads, kristallklare digitale Klänge und experimentelle, granulare Klangfelder.

Für mich ein Synthesizer vom Kaliber eines WAVEs. Definitiv ein Prachtstück von Waldorf. Auch von den äußeren Werten (Design, Verarbeitung). Lediglich die durch die etwas großzügigen Aussparungen doch etwas sehr viel wackelnden und deswegen mitunter deutlich schräg ausgerichteten Taster sind nicht ganz stimmig zum wertigen Rest.
