As an experienced eurorack musician, here's a set of patching strategies and module combinations that exploit Atlantix's architecture, integrating it in novel and musically rewarding ways:
Atlantix offers high-quality Thru-Zero (TZFM) linear FM on VCO A. Try patching in audio-rate signals from unconventional oscillators (e.g. Make Noise DPO, Instruō Cš-L, or a digital oscillator like the Mutable Instruments Plaits). This will result in much more complex spectra than using VCO B alone.
Combine Atlantix with a wavefolder (Intellijel Bifold, Tiptop Buchla 258t) or a Low Pass Gate (Make Noise Optomix). Since Atlantix can output raw waveforms (with the expander), send a sine or triangle to a wavefolder then through a LPG.
Exploit Atlantix’s percussive sync and snappy VCA with a trigger sequencer and external sample players. Use the ENV/GATE switch in Gate mode to turn the VCA into a percussive "hit". Patch gates from a trigger sequencer (e.g. Mutable Grids, or Euclidean Circles).
Patch VCO A and B to slightly detuned intervals and use SYNC tricks (try soft vs. hard) for metallic, lush chords typical of classic dub techno. Process the MIXER output through an external stereo reverb (e.g. Strymon BigSky) and a complex filter (e.g. Mutable Blades).
Leverage Atlantix’s rich internal mod matrix and S&H for generative textures, especially with external utilities:
Pair Atlantix with an external stereo panner (e.g. Happy Nerding PanMix or X-PAN). Use different outputs (main, expander’s filter outs, or post-VCA via external VCAs) for left/right feeds, especially with different waves or filter types (HP on one, LP on the other).
Patch the dedicated oscillator outputs into crossfaders (WORNG SoundStage, Befaco Morphader) for live blending and morphing between shapes. Especially fun when under CV control from Atlantix's Mod X or Y.
The ATLX expander provides a passive ring modulator. Try cross-patching wildly disparate signals (e.g., your modular with a dynamic microphone preamped to modular level, or a drum module and Atlantix's oscillator). Use the ring mod output for chaotic, metallic signals perfect for FX or percussion layers.
Exploit the mixer section’s AUX ins and normals. Use feedback by patching filter outputs back into mixer AUX, and cross-modulate AUX with CVs or audio. Enhance with an external matrix mixer (Doepfer A-138m) for feedback ecosystems.
Combine Atlantix with a polyphonic MIDI-to-CV interface (Expert Sleepers FH-2, Endorphin.es Shuttle Control). Sequence both VCOs independently for classic two-voice patches, dual bass/lead, or overlapping duophonic arpeggios, and automate envelope, filter, and VCA parameters with external LFOs or Euclidean rhythm generators.
Atlantix stands out as a flexible and powerful analog synth voice—its extensive normalization, expander options, and thoughtful modulating architecture make it a superb heart or satellite for any creative eurorack system. Pair it with CV manglers, exotic sound sources, or advanced effect processors for maximum creative discovery.
