# Sound Engine *** ### Overview Current's powerful sound engine includes two wavetable oscillators, a granular sampler, an additive sub oscillator, and a time-stretching sampler. These modules can be combined in different ways to create complex, hybrid sounds. Two morphing filters and dedicated FM and mixer panels provide additional sound shaping and routing options. This semi-modular approach makes sound design both accessible and deeply customizable. ### Key Features [Wavetable Oscillators](/current-manual/sound-engine/wavetable-oscillators.md) Current includes two high-fidelity wavetable oscillators powered by spectral processing, delivering alias-free waveform reproduction. Use the Position knob to explore dynamic timbral shifts across waveforms, enabling richly expressive patches. [Wavetable Wave & Warp Effects](/current-manual/sound-engine/wavetable-wave-and-warp-effects.md) Explore a diverse library of wavetables from raw analog classics to bowed strings and aggressive bass growls. Customize each wavetable with wave and warp effect slots, including formant shifting, wave shaping, and filtering. You can also drag and drop your own audio files to create custom wavetables. [Additive Sub Oscillator](/current-manual/sound-engine/sub-oscillator.md) Sculpt precise, powerful low-end with an additive synthesis engine that uses sine wave partials. Fine-tune harmonic content, apply wave-shaping and pitch envelopes, and inject movement into your bass with spectrum effects. [Sampler Engine](/current-manual/sound-engine/sampler-engine.md) Load loops, one-shots, or noise from the Stream or your personal collection. Advanced time-stretching keeps everything in sync with your project tempo, making the sampler a versatile layer or centerpiece in any patch. [Dual Multi-Mode Filters](/current-manual/sound-engine/filters.md) Route filters in series or parallel with morphing, comb, and vowel modes. Perfect key tracking ensures tuned resonance for musical and resonator-style effects. [FM& AM Modulation](/current-manual/sound-engine/fm-panel.md) Unlock deep modulation possibilities with a flexible FM/AM system. Any module can modulate another or even itself enabling harmonic enrichment, instability, and experimental textures. A built-in noise source adds an extra edge. [Mixer Panel](/current-manual/sound-engine/mixer-panel.md) The mixer panel gives you a clear view of your signal flow. Control levels, solo sources, send direct outputs, and shape your overall patch with intuitive gain controls. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
