Formats, requirements, and the fine print, all in one place. If the answer you need isn't here, ask us before you buy. We'd much rather answer a question now than have you hit a surprise later.
| macOS | macOS 11 or later. It runs natively on Apple Silicon, where rendering uses the Metal GPU, and on Intel Macs with an optimized CPU engine. |
|---|---|
| Windows | Windows 10 or later, 64-bit. Rendering uses the GPU on NVIDIA RTX 20 and GTX 16 series cards (2018) and newer. Every other machine uses the CPU engine instead, so a GPU isn't required. |
| Memory & disk | 16 GB of RAM recommended. 12 GB of disk space required. |
| Plugin formats | AU (macOS), VST3, VST, AAX, plus ARA2 in DAWs that support it. Standalone app on both platforms. |
ReStem will work equally as well separating a full mixed song as a drum track. The non-drum instruments will land in the "Other" stem.
Good enough that we finally shipped it, which we didn't do in ReStem 1. Live separation runs about a third of a second behind the original track, and your DAW makes up for that delay automatically. The offline modes still win on outright quality, though, which is why the selector goes all the way up to Best (Offline), and why we suggest rendering before you print a final mix.
No. All of the separation happens on your own computer, whether that's on the GPU or the CPU, and your files never leave your machine.
No. Licenses activate online per machine through your WaveMachine Labs account.
You get seven days of the full Pro feature set on your own sessions, after a quick email confirmation. The only catch is that the output has a short, quiet tone every few seconds until you buy a license. It's one trial per machine.
No. ReStem 2 installs next to version 1, with its own plugin identity, settings, and folders. Your old sessions keep loading ReStem 1 exactly as before, and nothing gets overwritten.
The separation engine was rebuilt from scratch. The biggest additions are live separation on the insert, which ReStem 1 couldn't do at all, and ARA2 processing right on the timeline. Every stem can now send MIDI, using the TrigNet trigger engine, and Auto Notes reads tom pitch and hi-hat articulations for you.
The rack of effects expanded as well. The Transient Restorer joined the rack on the kick and snare, sitting alongside the Look-Ahead Noise Gate and Transient Shaper that already run on every stem. The Separation Map is new too, and it shows the split happening as it plays. The seven stems, Drumagog replacement, the stem bus outputs, and local processing all carry over from ReStem 1. You'll find editions and pricing on the Editions page.
No, Core is the standalone app only. It uses the same engine and reaches the same top offline quality as Pro. But running as a plugin is itself a Pro feature, along with the live mode, the effects rack, and MIDI Output. If you want those, you can upgrade Core to Pro in place: buy the upgrade and re-enter your license.
ARA2 is built into Cubase, Nuendo, Studio One, REAPER, Digital Performer, LUNA, and Waveform, and on Windows also Cakewalk Sonar, Samplitude, and Mixcraft. In any other DAW, including Logic Pro, Pro Tools, Ableton Live, FL Studio, and Bitwig, ReStem 2 works as a regular insert.
The Drum Replacer works on the kick and snare, which are the drums replacement was really invented for. For anything else, there's MIDI Output instead: any stem can trigger any drum instrument or sampler, either live or through an exported MIDI file.
