One Plugin. Every Sound You Need.
Stop jumping between dedicated synths, samplers, and loop slicers. SourceLab 2 is one virtual instrument with an advanced wavetable engine, multisample playback, and loop slicing — plus 2,300+ presets from wavetable leads to Kontakt-style instruments, loops, arps, MIDI, and drums.
Finish beats faster.
Without the plugin shuffle.
Most virtual instruments do one thing — synth, sampler, or loops. SourceLab combines all three in one engine, so every sound type you need lives in a single plugin.
Other plugins give you one type of sound.
SourceLab gives you synth, sampler, and loop slicer in one.
Where most virtual instruments specialize in one approach, SourceLab combines an advanced wavetable engine, multisample playback, and loop slicing. Your preset library covers wavetable patches, samples, multisamples, loops, arps, MIDI, drum patterns, and hybrid combinations — all in one instrument.
Drums & 808s
Hard-hitting kits and trap-ready low end, ready to drop into your session.
Wavetable synths
Serum-class wavetable synthesis for modern leads, pads, and textures.
Samples & multisamples
Kontakt-style multisample instruments plus chopped loops — no separate sampler needed.
MIDI & chords
Built-in patterns and chord tools to speed up your writing process.
6 sound sources
Every preset uses up to 6 sound sources — each one a wavetable synth, sampler, or loop slicer.
Simple when you don't
Load a preset, start playing. No engineering degree required.
One virtual instrument. Every preset type you need.
SourceLab is not a DAW — it's a hybrid instrument you load in yours. Score melody, drums, bass, and texture by loading SourceLab instances and choosing the right preset for each part. That's the point: one plugin family instead of a shelf of separate synths and samplers.
- Wavetable presets, multisamples, loops, arps, MIDI, and drums — all in one engine
- Load multiple instances in your DAW — drums on one, melody on another, bass on a third
- Works for every genre — if you need the sound, SourceLab has a preset for it

No artificial limits
Most plugins are built for one job — synth, sampler, or loops. SourceLab combines all three in one engine, so your packs can mix wavetables, multisamples, sliced loops, MIDI, and drums without hitting a wall on day one.
Pro-grade delivery
Why ship your work through dated pack builders that compromise sound quality? SourceLab gives you a top-tier engine and effects chain — so clients get state-of-the-art content, not a compromised sampler experience.
Go beyond imagination
More producers and sound designers want to build their own content, plugins, and preset packs — and keep running into limits. SourceLab removes them. Design deeper, ship faster, and give your audience something only you could make.
This is what producers already created with SourceLab.
Real expansion packs built and shipped by the community — hear them in action.
The best part of SourceLab: it is open. Hundreds of samples, loops, MIDI, and drums — one file, one drag, and it works everywhere your clients need it.
