Welcome to the future of professional music production with SourceLab – the ultimate audio sandbox from Initial Audio. After over a decade of refining tools for creators, we’ve cra fted a plugin that stands above the rest: 6 sound sources, each capable of being a Wavetable Oscillator, Sampler, or Loop Slicer. Designed for producers, sound designers, and composers who demand excellence, SourceLab is your gateway to unparalleled creative control. Unmatched Versatility: SourceLab is the ultimate audio sandbox with advanced routing, a 6-layer MIDI sequencer, professional effect racks, and a preset browser with tagging. Layer wavetable synths with multisampled instruments or sliced loops in ways that redefine what’s possible. Welcome to SourceLab At first glance, SourceLab may look like a powerful preset machine – a massive library built for producers to quickly browse high-quality content for their tracks. But look deeper, and you’ll discover a full-blown audio sandbox. From Skrillex-style wavetable synths to hyper-real multisample-based instruments like pianos, guitars, strings, and more – SourceLab gives you everything. Sliceable, pitchable loops. Drum kits, drum loops, and performance-ready patterns. All powered by Zynaptiq’s industry-leading ZTX time-stretch algorithm, one of the most advanced algorithms on the planet today. Under the hood, SourceLab is built for performance: up to 6 sound sources per patch, each capable of loading wavetables, samples, or loops – or a blend of all three. At the core lies a powerful multi-layer MIDI sequencer. Create and arrange melodies, rhythmic patterns, or loop sequences, and stack them across layers to explore a whole new dimension of editable, generative musical ideas. Combined with advanced routing, modular FX racks, and a deeply optimized engine, SourceLab is not just a sound source – it’s a creative playground. A next-gen audio sandbox for producers to discover, build, innovate and share. Crafted for Excellence 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. 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. Our Goal Empowering Creators At Initial Audio, our mission is to empower professional music creators – producers, sound designers, and composers who shape the sound of tomorrow. SourceLab reflects this commitment, offering a platform that eliminates the frustrations of traditional workflows and puts control back in your hands. Unrivaled Freedom: Every preset in SourceLab is fully consolidated – samples, wavetables, loops, MIDI, all in one file, synced to your project BPM with ZTX quality for the Sampler and Loop Slicer. Share it with colleagues or clients across any DAW (FL Studio, Ableton, Logic, Pro Tools, Cubase – you name it), on Windows or Mac – it works seamlessly. Export and import via drag-and-drop – a professional workflow couldn’t be simpler. Creator-Centric Design: While some solutions impose restrictive ecosystems or ongoing costs, we believe the best content comes from you – the creators. SourceLab empowers you to build and share without barriers – craft multisampled pianos with 4th dimension layers, virtual analog synths from real tables, or granular-chopped loops, and share them as single files. Your success drives ours. A Platform That Evolves With You With SourceLab, you’re not just getting a plugin – you’re joining a platform designed to grow with you.
