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 crafted 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.

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.

Key Features:

• Six Independent Sound Sources – Each with 24-voice unison, FM, warp modes, granular engine and per-voice wavetable position.
• 14+ Modulators – AHDSR, LFO (user shapes & tempo-sync), multi-stage envelopes, note-release triggering and more for deep movement.
• Granular & Loop-Slicer Modes – Real-time size, density, direction and ±24 st pitch for rhythmic or cinematic textures.
• 6-Lane MIDI Sequencer – Master lane plus per-source routing; drag-and-drop MIDI import/export.
• Modular FX Racks – Six serial/parallel racks with compressor, reverb, multiband, delay and more, plus a master bus for final polish.
• Advanced Tag Browser & Library Consolidation – Every preset bundles its samples, loops, wavetables & MIDI into one portable file — no "missing sample" errors ever again.
• Heat Up 3 Compatibility – Load any of the 13000+ instruments from Heat Up 3's 61 libraries and take them further with SourceLab's new engine.
