"What is System 3? A System 2 on steroids? The illegitimate lovechild of System 1 and System 2? A modulation lover’s paradise? Or is it all of those?
It won′t surprise you to learn that our designs are heavily influenced by whatever we were playing with at the time.
For example, System 1, our stereo-friendly system, was birthed during late night sessions with the M/S Matrix, VC Panning Amplifier, Dual State Variable VCF and Dual Delay prototypes.
System 2 came from toying with those budget analogue mono−synths flooding the market, and dreaming of one with premium components, a well−spaced layout, and a lifespan measured in decades, not months.
System 3? Well, System 3 came from playing about with System 1 and System 2 in conjunction with our new Mini MIDI module. Mini MIDI′s ability to convert MIDI CCs directly into modular friendly CC, with all the control that offered over modulation, set us down an addictively creative path, and we knew we had to share it.
System 3 very much has the mono−synth vibe of System 2, coupled with some of the stereo−tricks of System 1, but it′s really about modulation and experimentation."
"System 2 is our second complete system, offering a creamy-sounding, creative
take on classic subtractive synthesis. Its ideal for powerful and creative bass
and leads, with unrivalled sound quality. Plus a number of ACL-only tricks up
its sleeve.

"System 2 is our second complete system, offering a creamy-sounding, creative

bass and leads, with unrivalled sound quality. Plus a number of ACL-only
tricks up its sleeve.
Honestly, we weren′t sure we′d get as far as
System 2 calling the first ‘System 1’ was a bit of a leap of faith! After all, a
key point of modular is that you can mix and match components. But we realised
lots of users were grouping our modules together in their racks anyway. Not only
that, but many had run out of space in their main rack and still wanted to add
some ACL kit. And then there were the people who wanted a complete, portable
live-friendly system for gigs. So we gave it a shot it′s all modular, after all
so you can still connect it however you like – and it worked!
So why
this configuration? Following the success of System 1, we received many requests
for a more conventional subtractive synth design (1 had a heavy focus on
creative stereo sound). So the focus is on creating powerful bass and leads,
with plenty of modulation options, whilst still allowing scope for
experimentation, and harnessing the unrivalled power and sound quality that make
our individual modules so popular. The result has some very distinct
specialities and the unmistakable flavour of our modules, and is designed to
slot easily into a bigger set-up too. Let′s have a walk through those
modules…
The sound sources
The main sound sources come
courtesy of a Multifunction Discrete VCO. This module ignores traditional
designs, offering a unique and powerful sound, plus ACL-specific innovations
such as multi-waveform-type sub-oscillators. These latter are modulatable and
fully-syncable to the main oscillator. In fact you can even mix and match
between five types of each. Having two of these allows super-phat, layered
sounds, or fantastic stereo or detuned voices. Not only that, but the linear
detune feature allows unique beating effects, the timing of which remain
unchanged from the lowest note to the highest, rather than speeding up and
slowing down proportionately to the pitch..
Reinforcing the VCO (and
adding a host of additional creative possibilities) is a Variable Sync VCO. This
is a precise, excellent sounding VCO, providing five simultaneous waveforms, a
VC variable-sync feature (that works brilliantly with the main VCO),
exceptionally powerful linear FM (you need to hear what this can do to liven up
System 2 bass patches to believe it), and loads more.
Keeping these
VCOs modules company are two Oktave modules allowing precise transposition of
sequences and melodies up and down by four octaves, or precision detuning by
+/-7 semitones.
Processing and mixing
On filtering duties,
we have placed our Discrete Core Ladder VCF. If you′re building a classic
subtractive monosynth-inspired system, what else to pick but a silky
liquid-sounding Moog-inspired filter? This design goes much further, though,
offering a unique features such as BOOST, which ensures that there′s no
low-frequency loss, even at high resonance settings. Not only that, but all
filter pole settings 6dB, 12dB, 18dB, and 24dB/octave have their own individual
outputs which can be routed and used simultaneously for some fantastic effects
(imagine, for example, an Oberheim Expander filter with Moog
characteristics).
Pulling the individual oscillator sounds together
is a Gate Mix module. This is our mixer-with-benefits… on steroids… allowing you
to combine up to four main sound sources (complete with CV/gate muting) plus an
Aux input (which could be anything from a fifth oscillator for power chords to
another mixer in your modular set-up). Ideal for uber patches, there′s also the
option to simultaneously tap into two groups (inputs 1+2 and 3+4) in addition to
the main sum of each, making gate Mix, in addition to many other things, a
simple high-quality stereo mixer.
Routing
Key to creating
great modular patches is the ability to duplicate audio and CV sources for a
range of parallel processing, mixing and syncing options. As such, we′ve
included two Multi II modules, suitable for everything from precise
synchronisation of multiple tone generating VCOs to waveform mixing and
subtraction. And the inclusion of two offers up far more potential for combining
your System 2 with your other modular gear.
Cutting shapes
Envelope
shaping comes courtesy of an Envelope X3. This module is based on the acclaimed
Roland 100M, but vastly enhanced to deliver peerless punch and consistency. It
delivers three ADSR envelopes, with potential for lightning-fast response, ideal
for drums, bass, and other sounds that benefit from fast and tight envelopes.
But that′s not all: Long and Short modes (with overlapping ranges) mean it′s
perfectly suited to pads and drones too. LFO duties are supplied by no less
than three of our prized QLFO modules. This design offers unprecedented
versatility for an LFO, going far beyond conventional modulation duties, with an
extraordinary frequency range from snail-slow to dog-whistle territory.
Four
simultaneous outputs per module offer a sine wave and three phase-shifted copies
– 90º (cosine), 180º (inverted sine), and 270º (inverted cosine) – allowing a
world of fun (more on that here). The frequency of these can then be voltage
controlled (with an attenuator at the input), while another CV input then allows
the LFO to be pitched by volt/octave, with solid tracking good over 2-3 octaves.
But that is not all the QLFO can do, it can even operate as a rudimentary sine
wave VCO – and remember… System 2 includes three of them!
Twice the
fun
In any modular system, VCAs are a fact of life, like shower
curtains, bedsheets, and toothbrushes. But – like shower curtains, bedsheets,
and toothbrushes – that doesn′t mean they can′t do a great job, look sexy and
generally be a joy to use! We like to think our VC Dual Amp modules fit the
bill, and so we′ve added two of them, offering up a total of four VCAs.These
linear VCAs all feature unrivalled accuracy and precision, as their unique
design ignores conventional designs and is based instead on circuits found in
precise measuring devices, such as oscilloscopes. They also offer an uncommon
level of creativity thanks to the ability to handle both audio and control
signals, and with innovative features like a summed output for each pair –
alongside the individual outputs – and an Aux input, enabling a range of fun
effects such as modulated stereo panning and crossfading.
On the road
again?
Whatever kind of noises you make with a modular set-up, at
some stage you′ll want to take that audio out into the world, and our Audio
Interface is the answer. Whether you want an unbeatable signal path from modular
system to studio (and vice versa), or to take it on stage and combine it with
other equipment (without needing an additional mixer), it delivers. The
combination of a studio quality signal path, flexible routing possibilities, and
a headphone amplifier – capable of driving both high and low impedance
headphones, with low distortion – makes the connection between these different
environments effortless and sonically transparent.
All of this is
contained in an 84HP EVZ-1 case, our lightweight, high-end Eurorack cabinet.
Precision crafted from , with red oak side panels to add stability and strength
(and a little sex appeal) it integrates our KAZU switching PSU and is wired to
our EVE-1 busboard, The result is one of the safest most consistent supplies for
your modules (ensuring the longest possible life and performance), with
extremely low background noise and simply outstanding sound quality.
Finally,
System 2 ships with an AC adapter, and 20 patch cables, so it′s ready to use,
right out of the box."
