At Initial Audio, our mission has always been to empower creators with tools that spark real innovation. SourceLab is the culmination of over a decade of expertise — a plugin designed to break free from the limitations of traditional workflows and deliver a seamless, professional-grade experience.
With six fully independent sound sources, each capable of acting as a Wavetable Oscillator, Sampler, or Loop Slicer, SourceLab offers a level of flexibility and sonic depth rarely seen in a single instrument. You can even fine-tune the wavetable position of each individual unison voice, or trigger oscillators and samples on key release, adding a new layer of realism and creative control to your sound.
But SourceLab goes far beyond engine design. Its intelligent consolidation system allows creators to export entire libraries — including presets, MIDI files, samples, loops, and more — into a single, portable file. Whether you’re building sound packs or collaborating with producers around the world, your work remains fully intact and cross-compatible across all major DAWs on both Windows and macOS.
No more “file not found,” “sample missing,” or “wavetable unavailable” errors — everything is self-contained.
While most plugins are limited to being a synth, sampler, or slicer, SourceLab unites all three — and more — in one powerful, optimized audio sandbox. Wavetables. Samples. Loops. Drums. MIDI. FX. Sequencing. It’s all here — streamlined, integrated, and ready to inspire.
This isn’t just a plugin. It’s a complete creative environment — built for professionals, designed to evolve with you, and engineered to redefine what’s possible.
Unleash Professional-Grade Power
Hybrid Engine
6 sound sources – combine wavetable synths, samples and loops in a new intuitive way that redefines creativity. Each source supports 24-voice unison, ztx time-stretch, warp modes, frequency modulation and more.
Modulation Suite
14+ modulators – AHDSRs with legato and sequencer triggering, LFOs with custom shapes and sync options, MSEGs with loop modes and node-based editing. Enables sound design that stands out.
Granular Engine
Apply granular synthesis to samples and loops – tweak size, density, pitch (±24 semitones), and randomization options like start position, gain, and direction. For added musicality, the granular engine includes an Arp Mode.
MIDI Sequencing
6-layer sequencer with a master lane and individual routing to each sound source. Trigger drums, synths, and basses independently or in sync – with drag-and-drop MIDI import/export.
Effect Racks
6 racks with compressor, reverb, delay, multiband, and more – route them serially or in parallel with drag-and-drop ordering. Create a master rack for final polish, delivering a pro-grade mix within the plugin.
Preset Browser
Advanced tagging system for genres and characteristics – filter by tags, add custom author notes and images, and share effortlessly via drag-and-drop as a single, consolidated file, BPM-synced for maximum portability.
