Arna 1snob is a free VST3 / AU reverb plugin for macOS, native on Apple Silicon (M1/M2/M3) and Intel. A one-click installer, no licence check, no nag — double-click and it drops the VST3 + AU into place. Then rescan your DAW.

Drop your email and the download link comes straight back while the public release is staged. The 1snob edition is free for personal and commercial music production.

— Step by step

install.

  1. requirements

    • macOS 12 (Monterey) or newer
    • Apple Silicon (M1 / M2 / M3) or Intel Mac
    • Any VST3 or AU host (Logic Pro, REAPER, Ableton Live, Studio One, FL Studio, Pro Tools, etc.)

  2. open the installer

    You get a Arna-1.0.0-macOS.pkginstaller. Because it isn't notarized yet, the first open needs a right-click: right-click the .pkg → Open → Open(a plain double-click will say "unidentified developer"). Enter your password when macOS asks — the installer drops the .vst3 and .component into the system plug-in folders automatically. No unzipping, no moving files by hand.

  3. rescan your DAW

    In REAPER: Preferences → Plug-ins → VST → Re-scan. In Ableton Live: Preferences → Plug-Ins → toggle "Use VST3 Plug-In Custom Folder" off and back on. In Logic Pro: it scans on launch; if Arna doesn't appear, restart Logic and let validation run.

  4. load & turn the knob

    Insert Arna 1snob on a vocal or drum bus. The knob starts at 0.30 — Room. Turn it right toward Bloom and listen for the tail to take over.

— Troubleshooting

if it doesn't show up.

The plugin isn't in my DAW's list.

First confirm the bundle is in the right place. From Terminal, run ls /Library/Audio/Plug-Ins/VST3/Arna.vst3— if you see the path, the bundle is installed. If your DAW still doesn't see it, force a rescan in the preferences and restart the DAW.

macOS blocks it ("unidentified developer" / "damaged").

The 1.0.0 installer is signed (ad-hoc) but not yet notarized, so the first open is gated. Don't double-click — right-click the .pkg → Open → Open. If a DAW later refuses the installed plug-in, clear the quarantine flag and rescan:

xattr -dr com.apple.quarantine /Library/Audio/Plug-Ins/VST3/Arna.vst3
xattr -dr com.apple.quarantine /Library/Audio/Plug-Ins/Components/Arna.component

Or: in System Settings → Privacy & Security, scroll to the bottom and click Allow Anyway next to the blocked entry, then reopen the DAW.

REAPER doesn't hot-reload the new bundle.

REAPER caches the loaded plugin until the FX window is closed. Close the FX chain, hit OK, reopen the FX chain — the new bundle will load.

Logic Pro says "validation failed".

Run auval -v aufx ARN1 1snb in Terminal to see the actual error. Most failures are caused by stale validation cache — delete ~/Library/Caches/AudioUnitCache/ and relaunch Logic.

How do I uninstall?

Delete the bundles from the two plug-in folders:

sudo rm -rf /Library/Audio/Plug-Ins/VST3/Arna.vst3
sudo rm -rf /Library/Audio/Plug-Ins/Components/Arna.component

That's it. Arna writes nothing else to disk.
