Qu-Bit Electronix Aurora Bedienungsanleitung
Aurora
quickstart guide
Welcome to Aurora, a spectral reverb capable of a wide
palette of sounds: from lush caverns and whale songs, to alien
textures you’ve never created before. And likely, will invoke a
hunger for exploration you felt when you first touched a modu-
lar synth.
Aurora uses a phase vocoder audio engine which separates
the input signal’s time and pitch domains. By blurring these sig-
nals you can achieve beautiful time-stretched tails, or cybernetic
metallic effects.
Since Aurora’s sonic response is entirely dependent on the
input signal, no two patches will sound alike, lending itself to
an infinite world of surprise and discovery.
Discovery. It’s why we’re here.
Description
Module Installation
To install, locate 12HP of space in
your Eurorack case and confirm the
positive 12 volts and negative 12
volts sides of the power distribution
lines.
Plug the connector into your case’s
power supply unit, keeping in mind
that the red band corresponds to
negative 12 volts. In most systems,
the negative 12 volt supply line is at
the bottom.
The power cable should be connect-
ed to the module with the red band
facing the bottom of the module.
Initial Knob Positions
*These are the recommended initial knob positions, but who
are we to pigeonhole you. It’s your party, throw it how you
want it!
11 Audio Input Left
Audio input for the left channel. Nor-
mals to both channels when no cable
is present in Audio Input Right.
Range: 10Vpp (AC-Coupled)
12 Audio Input Right
Audio input for the right channel.
Range: 10Vpp (AC-Coupled)
13 Audio Output Left
Audio output for the left channel.
Range: 10Vpp
14 Audio Output Right
Audio output for the right channel.
Range: 10Vpp

CV/Gate Inputs
Audio IO
1Warp
Pitch shifts up 3 octaves, and down 3
octaves. Tracks 1V/oct.
Warp CV input. Range: -5V to 5V
2Time
Blurs the amplitude component of
audio, time-stretching your audio into
long smeared sonic tails.
Time CV input. Range: -5V to 5V
3Blur
Smears the frequency component
of incoming audio, creating digitally
stretched spectral effects.
Blur CV input. Range: -5V to 5V
4Reflect
Morphs between different multi-delay
time zones.
Reflect CV input. Range: -5V to 5V
5Mix
Morphs between the dry and wet
signal.
Mix CV input. Range: -5V to 5V
6Atmosphere
Controls the spectral and time do-
main filters to shape your sound. Low
end = spectral whale songs. High end
= Icy, frequency-rich textures.
Atmosphere CV input. Range: -5V
to 5V
7Reverse
Plays the incoming audio backwards.
What more could you want?
Reverse gate input. Threshold: 0.4V
8Freeze
Locks the inputted audio, and holds it
until deactivated. Wouldn’t be a Qu-
Bit module without a freeze button!
Freeze gate input. Threshold: 0.4V
9Shift
Wouldn’t be a Qu-Bit module without a shift button either. Holding down Shift
provides access to secondary functions.
Shift+Reverse: changes the Fast Fourier Transform (FFT) size. This is
your spectral resolution.
FFT Size LED Color How It Sounds Fun Sounds To Use
4096 (Default) Blue Lush And Clean Physical Modeling, Synth Pads
2048 Green Best Of Both Worlds Wavetable Synths, Samples
1024 Cyan Comb-like Timbres Synth Drums, Simple Waveforms
512 Purple Aliens Are Inside My Module Vocals For Craziness, Synth Drums
10 USB
Used for firmware updates, alternate firmwares, and custom settings via the
options.txt file. To update changes on your USB drive, simply insert it into Aurora
while powered or at boot up, and Aurora will automatically update all files and
firmware! USB LED will flash white when the update is complete. See the table
below for the available settings:
Option Default Description
DSP_ORDER 1 (ON) Sets whether the vocoder feeds the delay or vice versa
FREEZE_WET 0 (OFF) Forces the blend setting to full wet when freeze is engaged
LATENCY_COMP 0 (OFF) Adds an internal delay on FFT SIZE samples to keep the FFT
and the dry signal in sync
ALWAYS_BLUR 1 (ON) By default blurring is always engaged, this setting can be
disabled to allow a cleaner signal to pass through when blur is
all the way down
For more information on how to change your custom settings, shift functions, and
more, scan the QR code on the back of this guide to grab the manual!
Shift+Mix: Adjusts the audio input level. Default level is indicated by
Blue LEDs. Bring the level up to use line level gear with Aurora.
Patch: Whale Songs
Slow and low inputs will take you into the abyss with spectral
whales singing all around you. Bring Blur down and send it a
unipolar LFO, bringing ebb and flow to the whale’s haunting
call.
FFT Size: 2048
Patch: Icy Shimmer
Transport your sound to a crystal shimmer palace with these
settings. Adjust the Atmosphere knob for filtering control to
create sweeping movements in your patch!
FFT Size: 4096
Patch: Percussive Textures
Jam on Aurora with this performative patch! With the Time
knob low, manual tweaking on the Reflect knob in this ex-
ample tangles and twists percussive sounds in ways that will
always deliver.
FFT Size: 2048
Patch: Contact
Emulate alien ship thrusters with a simple waveform. Morph-
ing between sine and pulse waves on Chord, for example,
changes the thrusters from subdued to overwhelming.
FFT Size: 4096
Patch: Sea Cave
Running drums through this patch sounds like Poseidon is rip-
ping it in his sea cave. Activate freeze to transform the noisy
wash into a slewed drone for additional dynamics.
FFT Size: 512
