VOLTRA Synth
Dark Hybrid Synth
$12.99
iPad
A dark techno synthesizer built like hardware: analog-style oscillators, Wavetable and Resonator engines, a 32-step sequencer and 260 presets. Standalone and AUv3.
VOLTRA Synth by Another Machines is a dark hybrid instrument for techno, cinematic electronic music, evolving movement and modern sound design.
NEW IN VOLTRA 1.1
Modulate any knob: drag an LFO, envelope, the multi-stage ENV, Chaos or velocity onto any control, with up to 16 links per preset shown live on the knob ring. The sequencer gains per-step Slide and Accent, ratchets and polymetric lanes, and GEN writes a style-true pattern in one tap. The renewed Resonator adds Mallet, Pluck, Bow and Breath exciters, oscillator feed and stereo body radiation.
HYBRID SOUND ENGINE
Two analog-style oscillators provide hard sync, wavefolding, ring modulation, unison and drift. A dedicated Sub/Noise section adds weight and texture. The Digital Engine switches between Wavetable and Resonator: scan 139 factory wavetables or shape physical resonant bodies with material, damping, decay, spread and excitation controls.
FILTERS, ENVELOPES AND MODULATION
Eight filter models - LP24, LP12, BP, HP, Notch, Comb, Analog and ZDF - move from deep low-pass weight to acid resonance, comb textures and animated sweeps. Amp, Filter and Aux envelopes handle precise dynamics, while the multi-segment Motion Envelope creates looping and evolving shapes.
Four tempo-aware LFOs, Macros, Chaos, velocity, pressure and the modulation Matrix connect movement across the instrument. Drag compatible modulation sources directly onto controls for fast assignments, or build detailed routes in the Matrix.
MOTION FILTER AND FX
Motion Filter combines filtering with tempo-synced movement, envelope response and a live display. A complete effect chain includes Drive, Bitcrusher, Chorus, Delay, Reverb, Compressor, Pump, EQ, Phaser, Flanger, Limiter and Shifter.
ARP, SCALE AND 32-STEP SEQUENCING
Create rhythmic material with the arpeggiator, Scale tools and a 32-step sequencer. Send Notes turns the sequencer into a note generator, while Value, Pitch, Octave, Velocity, Gate, Ratchet, Slide and Accent lanes shape each pattern, with independent lane lengths for polymetric movement. Euclidean generation, probability, ratchets, swing, rotation and per-step control support everything from compact techno loops to cinematic pulses.
PRESETS AND WORKFLOW
Explore 238 factory presets spanning sequences, basses, bleeps, acid, percussion, resonant tones, dark atmospheres, impacts and cinematic textures. A free 22-preset expansion is included in the internal Store. Search Factory, User and Expansion libraries, save your own sounds, import and export presets with the Files app, and work across four interface skins.
VOLTRA runs as a standalone instrument and as an AUv3 Instrument inside compatible hosts. Core synthesis, preset generation and audio processing run locally on the device. No account or internet connection is required for core operation.
Ratings & Reviews
VOLTRA 1.1 is a major update with a redesigned, faster interface.
• Modulate any knob: drag an LFO, envelope, the multi-stage ENV, Chaos or velocity onto any control. Up to 16 links per preset, shown live on the knob ring.
• Hardware-style sequencer: per-step Slide and Accent, ratchets from one to four hits and polymetric lanes. GEN writes a style-true pattern in one tap.
• Smarter, faster generator: every style programs its sound and its sequence like a producer, and an audio critic listens to each candidate.
• Renewed Resonator: Mallet, Pluck, Bow and Breath exciters, oscillator feed, stereo body radiation and a crisp live holographic view.
• Unison Spread on both oscillators, bass-preserving resonance on LP24 and a live route inspector in the Matrix.
• Faster launch, smoother scopes and living visuals on every effect, with lower CPU use.
All your presets and AUv3 sessions sound exactly as before.
