Initial Audio have updated SourceLab, available for $119.00 for this weekend only.
What’s new in version 1.4.0:
- Sequencer Redesign – Complete redesign of the sequencer for a more intuitive experience. The Master Sequencer’s range can now be adjusted, allowing it to be triggered alongside other sequencers or play individual notes simultaneously.
- New Arp Seq Mode – added a hybrid Arpeggiator + Sequencer mode based on the Heat Up 3 engine. Heat Up 3 instruments now utilize this mode natively.
- Smarter Controls – Adjust sequencer ranges easily with new +/- buttons or by dragging. You can now copy and paste notes between the Piano Roll and Arp sequencers with automatic quantization.
- Content Management – Added a “Rebuild Content Database” button to the menu. This ensures your browser is always up to date if you move or add presets manually outside of SourceLab.
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. 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.
Initial Audio’s 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.
