Black Corporation Xerxes

Black Corporation, the Japanese company that already gave us the CS-80-inspired Deckard's Dream, has come up with a replica of the legendary Elka Synthex. Soon available from Alex4.

Xerxes is an eight-voice polyphonic analog Synthesizer that features two discrete logic DCO’s per voice. Each DCO section offers four waveforms (triangle, saw, square, pulse), octave switch, transpose, oscillator PWM, PAM, ring mod, pulse width, and a volume knob. It offers an analog multimode filter (HP/BP/LP) as well as two LFO’s and 2 ADSR envelopes. Furthermore there is an analog BBD stereo chorus.

The synth is heavily inspired by the well-known Elka Synthex Synthesizer from the past but it is not a replica. It’s a completely new development that has many modern and clever new features. The interface was not taken from the vintage Synthex but is also heavily inspired without cloning it.

Main features:

  • 8-voice polyphonic analogue synthesizer
  • 2 discrete logic DCOs per voice
  • analogue HP/BP/LP filter
  • 2 LFOs
  • 2 ADSRs
  • polyphonic velocity and aftertouch
  • full MPE (MIDI polyphonic expression) support
  • analogue BBD stereo chorus
  • 4U rack size with detachable rack ears and wood side panels
  • 10 preset banks (x128)

ACL announced System 2

ACL announced the System 2, a dream synth for classic and modern sounds!

With System II Audiophile Circuits League presents a powerful modular Synthesizer with two full-featured Oscillators and an extremely musical Lowpass filter. Based on the Multifunction Discrete VCO and the Variable Sync VCO, System II serves with an unbelievably vast sound spectrum, from thick basses to aggressive Leads. The new VC Dual Amp provides a crystal clear sound, which can be perfectly integrated in the studio thanks to the high quality Audio Interface.

System II is a beautiful compact system, suitable for all situations!

Included modules:

  • Multifunction Discrete VCO
  • 2 x Oktave
  • Variable Sync VCO
  • Discrete Core Ladder VCF
  • Gate Mix
  • 2 x Multi II
  • Envelope X3
  • 2 x QLFO
  • 2 x VC Dual Amp
  • Audio Interface
  • EVZ1-Case- 6U 84TE (Inkl. Kazu PSU, EVE1 Busboard, AC Adapter 15V - 3.34 A)

Frap Audio

Frap Audio is a new division of Frap Tools dedicated to pro audio gear for the 500 series. The first product is a compressor/expander.

Dynamics 2806 is a mono compressor and expander. The circuit is relatively simple and straightforward to preserve the original sound qualities (it features a single VCA stage); still, the ways that all the parts interact with each other (and with the user) create a wide variety of behaviors that dramatically expand its functionalities in the box.

The upper section of the front panel sets the compressor parameters, and the lower part sets the expander ones. The interface is pretty much self-explanatory, but an expanded signal routing and lot of original solutions ‘under the hood’ make the response of the controls quite distinct.

While controls like ‘Ratio’ and ‘Threshold’ are quite conventional, the behavior of the ‘Attack’ and ‘Release’ knob was designed to interact with the incoming audio source by slightly adapting the response time to the articulation of the sound. In this way, the dynamics may be compressed or expanded, the original nature of the sound remains recognizable.

A peculiar control, on the other hand, is the ‘Transient’, which relates to the time management just mentioned. Since some sounds may have an extremely sharp and loud attack followed by a long, soft decay, conventional dynamic processing may alter their nature too much and make them lose their original footprint. The ‘Transient’ control is specifically designed to preserve the sharp transient of these sounds, without compromising the rest of the audio processing.

Since dynamics also has a lot to do with perception, and perception has a lot to do with frequencies, the Expander section features precise controls for high and low pass filtering so that the circuit will operate only over the right spot.

The two silver knobs at the center set the final amplitude of the processed and unprocessed sound for precise parallel treatments.

The compressor section has a feedback design, but its feedback point can be selected via a ‘Pre’ or ‘Post’ switch: it can be either straight out the VCA, or after the ‘Processed’ output, for precise make-up.

Flexible sidechain capability allows for external input processing or advanced insert operations, such as for de-essing. Moreover, the external signal can perform compression or expansion, and the compression can happen either on the primary, unprocessed sound or on the already-processed signal, with a ‘Sum’ switch.

A ‘Listen’ switch lets you monitor the sidechain of either the compressor or the expander, for precise settings (especially of controls such as ‘Contour’ and filters.

Finally, you can (true-)bypass the Dynamics 2608 as a whole with the dedicated switch, which lets you also bypass the processing section only, thus retaining the VCA “color.”

NAMM Show 2020

Alex4 will be represented at the NAMM Show this year with a big booth.

We will exhibit mixed systems with our sales brands, including: ACL, AJH Synth, Analogue Systems, Animal Factory, Birdkids, Cwejman, Doepfer, E-RM, Endorphin.es, Eowave, Flame, Frap Tools, Meng Qi, Supercritical Synthesizers, TouellSkouarn, UDO Audio, Verbos Electronics and Vermona!

This year the focus will be on the fun of modularity. Small daily concerts will show the visitors the different possibilities of the modular system: for example besides the classical use as a defined synthesizer you can hear how the modular system can be used as drum machine, processing or effect box.

We are looking forward to an exciting time with many visitors!
