What actually changed from the first ReStem?
WaveMachine Labs built its name on Drumagog, the drum-replacement engine that's been quietly sitting in professional sessions since the 2000s. The first ReStem, released as an offline drum de-mixer, took that same drum expertise and pointed it at the opposite problem: instead of layering a sample on top of a hit, it pulled a mixed drum recording apart into its component pieces. The catch was time. You bounced the file, waited for the engine to render seven stems, then got to work.
ReStem 2, out August 21, removes that wait for the first time in the product line. Insert it on a track in Pro mode and it separates kick, snare, hi-hat, toms, ride, crash and an "other" catch-all stem live, while the track is actually playing. The offline engine is still there, and it's now roughly twice as fast as the original for anyone who wants the maximum-quality "Best" render instead, but the headline change is that ReStem no longer forces a render-and-wait step into the workflow.
Why does live separation matter for remixers and DJs?
A drum-only separator sounds like a narrow tool next to a full multi-instrument system like iZotope RX or Melodyne's stem features, and it is: anything that isn't a drum hit gets dumped into that one "other" stem, so ReStem 2 won't lift a clean vocal or bassline out of a mix. But for the specific job it does, going live is a real capability shift, not a speed bump. Producers who bought old breaks, room-mic recordings, or a stereo loop with no multitracks have always had to render first and audition later. Now the separated kick, snare and hats sit on live faders the moment the track starts playing, which means a remixer can solo a break, mute the kit around it, or route a single drum into its own chain in real time, inside the same pass where they're already auditioning the material.
"ReStem does this live while the track plays in your DAW, or rendered offline for the best possible quality," WaveMachine Labs says on the WaveMachine Labs product page. "Either way, every drum ends up on its own fader."
What do you get for $99 versus $199?
ReStem 2 Core, at $99, is the standalone app only: drop a file in, get seven offline stems, no plugin formats and no live mode. ReStem 2 Pro, at $199, adds VST, VST3, Audio Unit, AAX and ARA2 support, the live separation engine, a per-stem effects rack, and the Drumagog-based replacer with automatic MIDI note assignment (toms sorted by pitch, hi-hats split into open, closed and pedal). Both editions keep everything local: WaveMachine Labs is explicit that nothing gets uploaded to a server, so the plugin works with the network cable unplugged.
