In my opinion, the Waldorf Music GmbH Quantum is as state of the art as it gets in 2019. 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. With 5 types of synthesis engines, including a soon to be released FM type engine, your sound palette will be overflowing with options for real.
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.
Rather than reinvent the wheel going into detail of every section, I’m going to point you at a developing video series by Tim Shoebridge in a YouTube video list below. For lack of a better description, I called the series a deep dive tutorial. It is not a basic synthesis tutorial. I was very comfortable with the level Tim speaks to here.

Manufacturer Specifications: click to open/close or jump to comments
Dual timbral: split or layered mode with separate stereo audio outputs
3 stereo digital oscillators each capable of four synthesis algorithms
Wavetable: Waldorf style with latest additions from Nave including speech synthesis, wavetable generation from audio and new features
Waveform: Waveform with up to 8 simultaneous waves per Oscillator in detuned or chordal mode with hard-sync, warp & PWM as well as tunable noise

Two analogue lowpass filters per voice each in 24 or 12 dB configuration using innovative link modes
Digital former: Additional digital algorithms per voice like comb filter, high-pass, band-pass & notch filters (Nave, Largo or PPG models), bit-crusher, drive and more
Flexible routing system for order of analog filters & digital former and individual oscillator routings
6 LFOs in poly and global mode with extensive parameter set
6 loopable envelopes
Komplex: multistage LFO/envelope modulator
Extensive modulation matrix with 40 slots and easy via-controller assignments
Intuitive modulation assignment via panel elements and control LEDs
Master effect rack of 5 slots for each timbre choosing from FX like phaser, flanger, chorus, reverb, drive, eq and more.
Compressor for main output
Step sequencer with step recording, parameter automation and scale-based pitch quantization
Microtonal pitch configurations capable of importing Skala scl files
Capable of polyphonic aftertouch via external MIDI inputs
Chord and latch buttons
Module-based preset system for effects, oscillators, step-sequenzer and Komplex modulator
Single-function potentiometer and encoder controls for intuitive editing
Visualisation and deeper sound editing via context-sensitive high-resolution capacitive multi-touch display
Spectrum Analyzer and Oscilloscope at various processing stages
Up to 10,000 sound patch capacity organized by banks, attributes, author and patch number.
Favourites lists for quick recall of sound patches like for set-lists etc.
Pre-loaded with wide variety of patches by acclaimed sound designers like Howard Scarr
MIDI output of local keyboard, wheels and assignable panel elements
Automation of sound parameters from MIDI inputs via MIDI CC learn function
Recording of samples from audio inputs or self-recording of audio outputs
4 GB internal Flash memory for presets, samples and wavetables
Pre-loaded with more then 1 GB sample data
Export & import of presets, sample & wavetable via SD card
Import of Nave presets
Mod wheel can be assigned to any parameter which can be modulated in the matrix or via quick assign
Pitch wheel can be assigned to each oscillator individually
Each of the 3 Oscillators of a single timbre can be used in one of three modes using samples:
Stereo Multi-Sampler with looping
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 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.
7 Sort Orders
3 Velocity Modes
Keyboard Latch chordal and non-chordal
If that’s not enough, individual patterns can be created in the step-sequencer including transpositions and scale quantisations.
2x stereo audio out for main and aux timbres
Stereo audio input for sample recording and real-time processing
High-Quality 24bit A/D and D/A converters
