Waldorf Quantum

Polyphonic Synthesizer (2019)

Hybrid analog-digital machine with sampling features designed by Axel Hartmann


OVERVIEW   61 Keys keyboard based on fatar, expensive grey metal case with 2 assignable wheels.
Big LCD touchscreen display with lush colors.

-Iridium is a desktop version with double voices but lacking analog filter

Terminal connectors:
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
Headphone out with separate level adjustment
Sustain pedal input
Control pedal connector also capable of CV input (0-5V sensitivity)
USB host type A connector for interfacing MIDI controller or USB drives for sample/preset exchange and software updates
USB device type B connector for interfacing computer or other class-compliant MIDI USB hosts like iOS devices **)
SD Card for sample/preset exchange and software updates
DIN MIDI In, Out & Thru
Integrated power supply unit


OSCILLATORS  quad-core ARM processor manages up to 8 voices polyphony (a bit limited) each composed by 3 "oscillators" with bi-timbral features The quantum is a kind of sumup of waldorf past plugin experience offering 4 different synthesis engine:
-wavetable with possible sample import by memory card with classic cycle mode ispired by PPG with classic travel mode with loop points
-waveform classic "analog" waves like saw, sine triangle, noise , with special kernel stack for roland super osc mode with special fat detune mode. Also massive unison mode stack all voices.
-particle importing samples (4GB of flash storage or sampling by input) for basically granular features with classic randomish  behaviour with pitch, spread, position jitter , attack and decay.
-resonator generates tones based on an exciter signal which passes through a band-pass filter bank. Remind classic Virtual analog from the nineties.

FILTER  a dual-analogue self-oscillating low-pass filter (with 12/24dB slopes). There are four types of low-pass filter (including saturated/ driven versions) and eight configurations routing of filters. There are independent cutoff + resonance controls for each filter . It is possibile to switch to digital filter "Former"  with HP, BP, Notch, bitcrusher and drive, plus filters ispired by classic hardware from the past or plugins.

LFO 6 modulators capable of audio rate speeds (up to 100Hz frequency) with special envelope AD, can be synched to main master clock. Special Komplex Modulator allows to design a modulation mode using the finger on the screen.

ENVELOPE six envelopes with standard ADSR and 2 special looping modes with possibile random fluctuations. 

Sequencer / memory

SEQUENCER     32-step note sequencer

EFFECTS Five simultaneous effects blocks are available with eight effects algorithms are on offer (phaser, chorus, flanger, delay, reverb, EQ, drive and compressor). Effects such as delay can be synched to the whole machine (eg. sequencer and lfo)

SEQUENCER features a very basic 256 steps sequencer, but syncable to external Midi clock.

MEMORY  Up to 10,000 sound patch capacity
