Download the Xaoc Batumi II + Poti II Manual PDF
The Xaoc Batumi II, especially with the Poti II expander, is a deeply creative, performance-friendly, and modulation-focused quad LFO with optional audio-range VCO abilities. Below are patch strategies, module interactions, and creative workflows that harness its full potential in your Eurorack setup.
Pair With: Make Noise Maths, Intellijel Quadrax, ALM Pam's New Workout, Mutable Instruments Stages (as step sequencer). - Patch: Use Batumi II’s quadrature, divided, or multiplied modes to create phased or related LFOs. Send each to modulate amplitude, decay, or stage length of different envelope generators. Now your envelopes evolve over time or create polyrhythmic modulation. - Creative Use: Animate the speed of envelopes for generative, non-repeating modulation. Batumi II’s random outputs (stepped/smooth) into sequencer CV inputs for melodic motion or rhythmic gating.
Pair With: Mutable Instruments Plaits, Make Noise DPO, Tiptop Z3000. - Patch: Switch Batumi II into audio rate (Free Mode, with 1V/oct tracking), use two channels as VCOs. Patch one out to modulate the FM input of a traditional analog oscillator, and vice versa. - Creative Use: Exploit exact phase control and resets for experimental FM/PM synthesis. Use phase or wave switching modulation via Poti II for evolving timbres.
Pair With: Mutable Veils, Intellijel Quad VCA, Befaco AB+C, FX modules like Strymon Magneto. - Patch: Use Batumi II’s assignable waves to modulate four channels of a quad VCA. Send diverse modulation to volume, filter cutoff, dry/wet mix, delay repeats, etc. - Creative Use:* Animate multiple FX parameters for immersive, spatial textures. Poti II’s individual attenuation keeps the mix subtle or intense.
Pair With: 4ms Quad Clock Distributor, ALM Pamela’s Pro Workout, Mutable Grids, Malekko Varigate, Tempi. - Patch: Use Divide or Multiply mode—sync Batumi II to a master clock and use divided/multiplied outputs as clock/gate sources for logic or trigger modules. - Creative Use: Generate interrelated patterns for auxiliary percussion, modulation, or switching FX paths. Patch Batumi II’s random stepped output to a logic/counter for wild generative rhythms.
Pair With: Mutable Instruments Rings, Tiptop Z-DSP (or any wavetable oscillator). - Patch: Assign unique waveforms per channel, shape-modulate with CV through Poti II, and use these as evolving CV sources for a wavetable oscillator’s morph or position input. - Creative Use: Animate audio timbres or filter curves with simultaneous, CV-morphing shapes. Modulate the shape change rate with Batumi’s own CV inputs.
Pair With: Happy Nerding PanMix / Joranalogue Mix 3 / Make Noise X-Pan. - Patch: Batumi’s LFOs go to pan/CV inputs of a quad panner. Shape and offset each output via Poti II. - Creative Use: Envelop soundscapes in evolving, 3D movement across a stereo or multi-channel field.
Pair With: Doepfer A-148, Mutable Kinks, RandomSource S&H, Erica Synths Black S&H. - Patch: Route Batumi’s stepped random outs to multiple sample & hold modules clocked differently or at rates derived from Batumi itself. - Creative Use:* Generate four parallel, oddly correlated random voltages for evolving modulation or melodies.
Pair With: Polyphonic synth voices (Doepfer A-111-4 Quad VCO, Endorphin.es Godspeed, Mutable Instruments Polyend). - Patch: Use Batumi II’s VCOs each tuned/tracked to a separate voice. Assign independent shapes, CV modulate them, or use global phase/frequency relationships for coordinated timbral evolutions.
Pair With: ALM Boss Bow Two, Ritual Electronics Miasma, expressive controllers. - Patch: Use reset/sync inputs with triggers/gates from performance controllers or logic for live phase changes, switching between rhythmic and free modulation on the fly. - Creative Use: Live polyrhythmic morphing, macro modulation, or staged texture evolution—Poti II lets you jump between preset wave shapes or depths per channel on demand.
Pro Tips: - Exploit separate shape assignment and attenuation per channel for ultra-fine control—think of Batumi II/Poti II as a ‘control voltage designer showcase.’ - Use Batumi as a clock source for logic or sequential switch modules for meta-sequencing (i.e., using LFOs to clock or flip sequencer stages). - Patch Batumi’s phase mode into a quad filter bank’s cutoff for swirling, rotating filter animation.
