Install guide

Every plug-in installs the same way. Lucky Beats and Synth'O'Ween have their own step-by-step on their pages.

macOS

Unzip the download.
Double-click fix_mac_plugins.command when it's in the zip: it installs, unblocks and rescans the plug-in for you.
Or copy the .vst3 files to ~/Library/Audio/Plug-Ins/VST3 and the .component files (AU) to ~/Library/Audio/Plug-Ins/Components.
Restart your DAW and rescan plug-ins. In Ableton Live: Settings → Plug-Ins → Rescan.

Windows

Unzip the download.
Copy the .vst3 folders to C:\Program Files\Common Files\VST3.
Restart your DAW and rescan plug-ins. In Ableton Live: Options → Preferences → Plug-Ins → Rescan.
If SmartScreen warns about a standalone app, click More info → Run anyway (the apps are not code-signed yet).

Linux

Unzip the download.
Copy the .vst3 folders to ~/.vst3 (Bitwig, Reaper, Renoise, Ardour) and the .lv2 folders to ~/.lv2 (Ardour, Carla, Qtractor).
Restart your DAW and rescan plug-ins. Builds are for x86_64 with glibc 2.35 or newer (Ubuntu 22.04, Debian 12, Fedora 36 and later).

If macOS blocks a plug-in

The plug-ins are not notarized by Apple yet, so macOS may quarantine them. Paste this into Terminal, then restart your DAW:

xattr -dr com.apple.quarantine ~/Library/Audio/Plug-Ins/VST3/Halcyon.vst3 ~/Library/Audio/Plug-Ins/VST3/MixPilot*.vst3 ~/Library/Audio/Plug-Ins/Components/Halcyon.component ~/Library/Audio/Plug-Ins/Components/MixPilot*.component

What's new

Release notes

Halcyon

Wavetable synthesizer

v1.3.0LATESTOct 19, 2026

NewClassics: 10 categories and 301 presets in the spirit of famous instruments, from the 70s mono ladder synth and the 80s polysynths to FM keys, the acid bass line box, the analog drum machine, the late 80s workstation, the semi-modular and the 8-bit sampling computer.
NewSampler oscillator mode: play one of the built-in sources or your own WAV, AIFF, FLAC or OGG file from its root note, one shot, looped with a crossfade or ping-pong.
NewMPE: turn it on in the Voice panel and each note gets its own pitch bend, pressure and slide (CC74). Slide is also a new modulation source.
NewFavorites and tags in the preset browser: star a preset, filter by automatic tags (Mono, Arp, Sampler, Bright, Wide…) or add your own.
NewVital import brings the embedded sample along and plays it in Sampler mode.
NewUpdate notice: a small UPDATE badge under the logo when a new version is out (can be switched off in the SKIN menu).
Improved2,342 presets, now identical on Mac and Windows, and neighbouring presets in a category no longer sound alike.

v1.2.0Oct 17, 2026

NewSkins: the SKIN button switches between six looks (Vintage, Midnight, Synthwave, Olive Drab, Studio Light, Graphite). Your choice is remembered.
NewEnvelope attack, decay, sustain and release are now modulation destinations: velocity to decay, LFO to sustain, macro to release…
ImprovedDrums rebuilt: 70 sounds in 16 families (808, punchy and rumble kicks, snares, claps, hats, cymbals, toms, congas, rims, cowbells, shakers, metal, zaps), each named after what it is. Macros: tune, decay, tone, tail.
ImprovedThe version number is shown under the logo.

v1.1.1Oct 16, 2026

FixedThe preset arrows now step through presets in the same order as the browser.

v1.1.0Oct 16, 2026

NewImport Vital (.vital) and Serum 2 (.SerumPreset) presets with the IMPORT button or by drag and drop: wavetables, macros and their names, modulations and effects come along. Halcyon lists anything it had to approximate.

MixPilot

Assisted mixing & mastering

v1.2.1LATESTOct 27, 2026

NewFree EQ bands: add up to 12 bands of your own on top of the automatic EQ, each one bell, shelf, notch or cut, static or dynamic, on Stereo, Mid, Side, Left or Right, with solo to hear what it does.
NewAnalyzer modes, freeze and a piano strip under the spectrum to see notes as well as frequencies.
NewResizable window (60 to 200 %): drag the bottom-right corner. MixPilot remembers your size for every new window.
ImprovedA more open, airier master: the styles aim for a little less low end and more air on top, the Master compresses and clips less and lets transients and highs through, and stereo widening stays moderate so highs never turn harsh.
ImprovedAIR fader centred at 0 like the others: up for air and sparkle from 10 kHz, down to soften. Your current AIR settings are kept.

v1.1.1Oct 21, 2026

ImprovedMixPilot Track and MixPilot Master are now listed under Rems Plugins in your DAW, next to Synth'O'Ween. Existing projects open unchanged.

v1.1.0Oct 21, 2026

NewEditable EQ: after the analysis, every EQ band has a point on the spectrum. Drag it up or down for gain, left or right for frequency (Shift for fine moves). Double-click returns a band to the analysis, right-click resets them all.
NewOn MixPilot Track, your edits sit on top of the automatic correction and stay in place when it updates. On MixPilot Master, the points move the EQ sliders.
ImprovedEdits are saved with your project and can be automated. Existing projects open unchanged.
