Creative Patch Tips for the Hexinverter Orbitals Step Sequencer

The Hexinverter Orbitals module is an exceptionally deep step sequencer for eurorack with a range of flexible features: dual 8-step/16-step operational modes, bipolar output, voltage-addressed steps, per-channel length/mode/gate control, and extensive CV/gate routing.

Below, I’ll guide you through patch ideas and modulation concepts to create distorted percussive sounds, crazy basslines (à la dubstep/DnB), and haunting atmospheric pads.

Essentials: Orbitals Modulation Features

Modulate Orbitals Using: - Step CV and gate sequencing (of course). - Bipolar output switching for sharper/stronger modulations. - Voltage-controlled step addressing for non-linear, evolving patterns. - Transpose input for real-time or sequence-driven shifting. - Per-channel mode switching (random, pendulum, CV, etc.). - Clock rate modulation, both externally and internally. - CV and gate outputs to trigger or modulate external sources (VCO, LPG, VCF, etc.).

1. Distorted Percussive Sounds

Patch Strategy:

• Use one sequencer row (A or B) as a trigger/gate source for drum modules or noise/VCAs.
• Patch CV outs into heavily overdriven VCA/VCF or a waveshaper/distortion module.

Modulation Techniques:

• Pendulum or Random Mode (MODE knob): For unpredictable, glitchy rhythms.
• Gate Length (GATE knob): Turn up for longer, overlapping pulses—send to a distortion module (wavefolder, bitcrusher, etc.).
• Bipolar Output: Flip BIPOLAR on and set output to ±5V for aggressive modulation of distortion drive, filter cutoff, etc.
• Voltage Address Step Mode (CV/CLK modes via MODE + RST/CV in): Run a noisy/random LFO into RST/CV; this scrambles step position, creating varied triggers and unevenly spaced events.

Example Patch:

1. CV OUT → filter cutoff or VCA CV input (post-distortion).
2. GATE OUT → drum module/EG, or trigger noise burst through a VCA.
3. Add a random or stepped LFO to RST/CV in (CV or CLK mode) for evolving, broken percussive loops.

2. Crazy Dubstep / Drum & Bass Basslines

Patch Strategy:

• Sequence VCO/VCF pitch, wavetable selection, or complex waveshaping.
• Use the Transpose input or external CV for bassline interval jumps/riffs.

Modulation Techniques:

• 16-Step Mode: Use both rows as one for longer, evolving phrases.
• Transpose Input: Plug keyboard for pitch bends/glides; or use a sequenced CV for pitch jumps typical in DnB/dubstep.
• Reverse Input + Random Mode: Send gates to the REVERSE input, switching up bassline playback direction for stutter/glitch effects.
• Bipolar switch with ±10V (jumper): Get extra pitch range and drive harder VCO FM inputs.
• Step Gating: Use switches to mute/enable steps and create syncopation.
• Length knob: Unusual loop lengths (e.g., 5 steps) create polyrhythmic movement.

Example Patch:

1. CV OUT → VCO 1V/OCT (set to deep sine/saw).
2. GATE OUT → sample & hold, or sync envelope for filter cutoff “notches.”
3. TRANSPOSE IN → arpeggiator or modulation, for wild interval jumps.
4. RST/CV IN (CV/CLK mode) → LFO or S&H for pitch-scrambling lines.
5. Experiment with clock rate modulation (patch an LFO into clock input).

3. Haunting Atmospheric Pads

Patch Strategy:

• Use slow rates (RATE knob) for gradual, textural changes.
• Sequence filter cutoffs, FX mix levels, or wavetable positions for evolving sound.
• Double up sequencers for parallel modulation paths (e.g., one for VCF, one for FX/CV).

Modulation Techniques:

• Random or Pendulum Mode: Adds subtle, organic non-repetition.
• Bipolar Mode on ±2.5V output: Perfect for gentle LFO-like modulation.
• Gate shaping: Long gate times for droning vactrol/VCAs.
• CLK OUT: Use to sync slow LFOs/clock dividers for layered atmosphere.
• Voltage-addressed mode: Use a wandering S&H or slow random CV to “morph” through scenic step values.

Example Patch:

1. CV OUT to VCF cutoff, reverb mix level, or wavetable morph input.
2. GATE OUT to control an LFO reset or trigger slow EGs.
3. Run step modes in random/pendulum and set rate to very slow values.
4. Summing Orbitals’ CV out with another LFO via a mixer for added modulation complexity.

Key Bonus Tips

• Experiment with OUTPUT LEVEL jumpers (±2.5V, ±5V, 0–5V, 0–10V) to match/trick your downstream modules! More voltage = wilder modulation.
• Patch external modules (chaos modules, random clocks, audio rate LFOs) to RST/CV and clock inputs for totally bespoke rhythms and motion.
• The SLAVE B>A switch is your secret to instantly layered, evolving 16-step mod sequences—try pairing stepper rhythms or blended gate patterns.
