Elastic OSC Is Now Available for Mac and PC: The Mutable Instruments Plaits-Style Synth Goes Desktop
The Beloved Macro Oscillator Gets a Full Desktop Release with LFOs, MPE, and 500+ Presets
5,0 / 5,0 | 
A lot of people have been waiting for this one: Elastic OSC is making the jump from iOS and Android to desktop. The brilliant take on Mutable Instruments Plaits by developer Oliver Greschke is now available as a plugin and standalone application for macOS and Windows, and it brings a handful of extras that go well beyond what the original module ever offered.
Elastic OSC for Desktop: Everything You Need to Know About the Plaits-Inspired Synth Plugin
From Mobile to Desktop
Elastic OSC is built on the open-source algorithms of the Mutable Instruments Plaits macro oscillator, but treats that as a starting point rather than a ceiling. The iOS version has been turning heads for a while, and the Android version followed more recently. The desktop release was the obvious next step, and it’s arrived with a full feature set that adds meaningful depth to an already strong concept.
At its core, Elastic OSC packs 24 oscillator models covering FM, VA, wavetable, additive, granular synthesis, physical modeling, chords, speech, drums, and more. What makes it genuinely stand out is everything wrapped around those models.
Dual XY Pads and Elastic Automation
The interface is built around two expressive XY pads. The first gives direct control over the Plaits-familiar parameters: Frequency, Harmonics, Morph, and Timbre. Fast, dramatic sound changes happen intuitively here. The second pad is dedicated to effects, adding a completely separate dimension to sound shaping.
What Elastic Instruments calls Elastic Automation is the real magic trick. Movements across the pads can be recorded directly inside the plugin and saved as presets, with automation runs up to four takes long. According to developer Oliver Greschke, this produces more organic and often more surprising results than drawing automation inside a DAW. And here’s the clever part: these Elastic Automations stay active even when you switch between oscillator models, which opens up some genuinely unexpected sonic territory.
Four LFOs, MPE, and Over 500 Presets
The desktop version ships with everything that had to be unlocked separately in the mobile app, including four LFOs with an LFO mixer for routing modulation across Frequency, Timbre, Morph, Harmonics, Filter, and Pan. LFO speed and shape can themselves be automated, which adds another layer of movement to an already expressive instrument.
MPE support rounds things out at the top. With Glide X, Glide Y, and Pressure, up to eight synthesis parameters can be controlled per note, and MPE gestures work polyphonically, so each individual voice carries its own expression. Pair this with an MPE controller like the Intuitive Instruments Exquis* or the Expressive E Osmose* and Elastic OSC becomes a seriously expressive instrument.
Over 500 presets are included, with contributions from Arovane, Robert Lippok, Nerk, and Peter Kirn among others.
Verdict
Elastic OSC for Desktop is a well-timed release that makes a strong mobile concept fully accessible in a professional studio context. The dual XY pad approach, Elastic Automation, and MPE support add up to something genuinely distinctive, and at €39 during the intro period the entry point is easy to justify. Anyone who loved Plaits but wanted more flexibility in software form should take a close look.
Price and Availability
Elastic OSC is available now directly through Elastic Instruments at an intro price of €39, with the regular price sitting at €45. It runs as a standalone or as a VST3/AU plugin on macOS 10.14 or later and Windows 10 or later. iOS and Android versions remain available as well. Elastic Instruments will also be showing the plugin at Superbooth 2026 at booth Z380, alongside other Berlin-based developers.
