Intellijel Atlantix

Synthvoice from Intellijel

With Atlantix, Intellijel presents the greatly expanded successor to the popular Eurorack Synthvoice Atlantis. If you compare the two modules, it quickly becomes clear that Atlantix has more of everything. What has remained is the clear layout, which corresponds most closely to the Roland SH-101. Atlantix is capable of far more than the usual repertoire of tried and tested Bass and lead sounds with 1-2 oscillators. At least when it comes to FM capabilities and the filter, Synthvoice can certainly compete with the in-house semi-modular synthesizer Cascadia in terms of FM capabilities and filters. The module is very well thought out and offers enormous creative potential.

Oscillators, filters & modulations

We start with the two oscillators, each of which has a frequency range of over eight octaves. Oscillator B can be switched to LFO mode, just like its predecessor, and therefore also acts as a modulator. Oscillator A is capable of PWM, Thru-Zero FM as well as hard and soft sync. In addition, a sub-oscillator with -1/-2 octave spacing follows the frequency of VCO A. The waveforms of the first tone generator (square wave with PWM and sawtooth) as well as the noise generator and the sub-oscillator are present in parallel in the mixer. The noise generator provides white and pink noise. The aux channels are internally normalized to VCO A triangle/VCO B square for aux 1 and VCO A sine/VCO B sawtooth for aux 2, but the signal is replaced as soon as a cable is plugged in. The ring modulator output of the Atlx Expander or the Sample & Hold output, which generates an analog bitcrush at oscillator level with two square waveforms at the inputs.

Oscillator B appears in the signal path with two waveforms in the mixer and is present with four waveforms on the modulation buses X and Y, which serve as a switchable modulation source in the FM index and in the filter. The two modulation busses are primarily fed by VCO B; S&H, noise, filter and VCA are also present here for more extreme results and can be assigned directly without patching.

The mixer is followed by the multimode filter with six flavors Lowpass 12 & 24dB, Bandpass 12 & 24dB, Highpass 24dB and phaser. There are four CV inputs with attenuators to modulate the filter, which should be enough in most cases. If you go by the normalizations, the VCA with switchable overdrive is the end of the signal path, which is modulated with the ADSR envelope. The same envelope is also used to modulate the filter as well as the pitch and pulse width of VCO A. Thanks to the numerous CV inputs, it is no problem to integrate additional envelopes into Patch.

Expandable? - Absolutely!

Without a doubt, Atlantix is a powerful and extremely versatile analog synthesizer voice. A sequencer or a MIDI interface to breathe life into the module. The Atlx Expander enriches the Synthvoice with an input-side normalized ring modulator and gives you parallel access to all the waveforms that the oscillators can generate. To expand the sound spectrum, we recommend the Bifold Wavefolder, an incredibly powerful tool for creating organic and/or metallic sounds. With an additional envelope and a digital multi-oscillator, Post can really take off!
