Minimal Audio Current (Perpetual) — Free Download

Core Sound Engines

Current integrates five distinct sound generation approaches. Its spectral wavetable oscillators offer extensive waveform manipulation, including formant shifting, wave-folding, and filtering, with rich unison and anti-aliasing. The granular engine transforms samples into evolving textures and rhythmic patterns, featuring layer sequencing and multi-position playback for detailed control.

An additive sub oscillator focuses on creating substantial bass layers with harmonic controls and integrated drive modes, plus shortcuts like ‘knock’ and ‘sub lock’. A time-stretching sampler allows for flexible pitch and time manipulation of audio, with a classic re-pitch mode and stereo widening options. Dual filters provide over fifty modes, including morphing, vowel, and comb types, with key tracking and gain-compensated routing.

Modulation and Control

A flexible modulation system lets you drag and drop modulators to any destination, swap types without losing connections, and cross-modulate sources. This is complemented by a curve sequencer for drawing custom modulation shapes, a five-stage envelope generator with BPM sync and loop modes, and a morphing LFO with randomization and fade options.

Envelope followers add dynamic modulation responding to any sound source, enabling creative gating or ducking. Full support for MIDI and MPE keyboards is included, with standard control signals like key-tracking and aftertouch available. This makes the instrument highly expressive and adaptable to various performance styles.

MIDI Effects and Music Theory Tools

Current includes two integrated MIDI effects to spark creativity. An arpeggiator converts notes into melodic sequences with independent rhythmic and melodic modes, plus exponential rhythms and randomization. A chord generator produces seven distinct chords that stay in key, with presets for voicings and a randomize function for exploration.

In the keyboard area, you can set the instrument to your track’s key, and all relevant parts—samples, scales, and chords—automatically stay in tune. This integration allows for seamless experimentation with progressions and melodies without worrying about key mismatches, making it a powerful songwriting tool.

Workflow and Practical Applications

Current is designed for deep sound design sessions, allowing you to layer granular textures, sub bass, and spectral wavetable sounds into rich compositions. The modulation matrix and sequencer are ideal for creating evolving pads and rhythmic, animated sequences directly from the instrument, reducing the need for extensive external automation.

In a performance context, the keyboard and chord generator let you play in key with one finger, while the arpeggiator adds complex patterns. The envelope followers and filters can be used to create side-chain-like effects or rhythmic gating. This makes Current suitable for producers and performers looking to build full arrangements from a single, unified tool.
