Intellijel Atlantix Dual-Oscillator Subtractive Analog Synth Voice Eurorack Module

The Atlantix is an analog, complete subtractive synthesizer voice condensed into a single 42HP module. It's quick to dial in huge bass or lead sounds, and easy to push it into new sonic territory. Dual VCOs, Multimode VCF, VCA with Drive, S&H, Noise, and an ADSR envelope; all of the building blocks needed to expand or start making sound in your rack. With 32 patch points and a selection of routing switches, you can remix these blocks into something all your own.

Oscillators - Advanced TZFM and Flexible Mixer
The Atlantix uses two triangle core voltage controlled oscillators (VCO) which respond in a musically pleasing way to frequency modulation. The Atlantix primary VCO (VCO A) is capable of thru-zero frequency modulation and has a dedicated amplifier for controlling FM depth (FM INDEX). The modulation oscillator (VCO B) can be used as either an LFO or VCO. The highly flexible architecture allows you to route VCO B as a modulation source or stack it as a secondary VCO all by the flick of a switch or slider. VCO B also has a bonus "spike" waveform output which is a square wave with fixed HPF, similar to the Buchla Easel. Both oscillators track very precisely over eight or more octaves.

In the mixer section, you can adjust the balance of the primary oscillator's waveforms, sub-oscillator noise, and two auxiliary inputs that are normalled to additional VCO A waveforms or VCO B waveforms. The auxiliary inputs also allow you to patch other external signals into the mix.

The second Auxiliary input has a switch that allows you to route the source between the mixer sum or directly into the VCA (post-VCF). The latter is a way to pass an unfiltered fundamental signal to the final VCA stage and then blend it with filtered audio from the VCF. This draws inspiration from the architecture of the CS-80 where a sine wave is mixed with the filtered audio to make glassy tones with some added harmonics.

Multimode Filter - From Drips to Growls
The filter section (VCF) is a discrete cascaded 4-pole multimode filter with lowpass, bandpass, highpass, and phaser (multi-notch) modes. The filter can self-oscillate which produces a very clean sine wave that also tracks 1V/Oct. The VCF has three frequency modulation sources, two of which are normalled to the external pitch and envelope and have switches for polarity.

Envelope - A Classic ADSR
The envelope section is an analog ADSR with three timing ranges: slow, medium, and fast. It can be gated externally or via a manual gate button located in the center of the panel. The ADSR is routed through a VCA which can be used for level or velocity control.

Modulation - Random, Feedback, and Built-in Routing
Two eight-position rotary switches allow you to select from eight different modulation sources and route them to outputs MOD X and MOD Y. Each switch also has a polarity control and an option to level shift between unipolar and bipolar operation. MOD X is normalled to VCO A frequency modulation and MOD Y is normalled to VCF frequency modulation. The dedicated outputs allow for further creative modulation patching.

Four of the Input jacks have normal switches to change your patch without the need for cables.

The analog Sample and Hold (S&H) circuit is normalled to the white noise source and can be clocked by VCO B, an external clock source, or via the gate input for per-note synced randomization.
