Install

MINERVA Space Echo runs on macOS 11 or later, on Apple Silicon and Intel Macs, as an Audio Unit and a VST3. It is aimed at Ableton Live but works in any AU or VST3 host.

Download

Download the installer (MinervaSpaceEcho-macOS.pkg): always the newest release, no GitHub account needed. The latest release page has the release notes and a zip of the plug-in files; older versions are on the Releases page.

File Use it to
MinervaSpaceEcho-macOS.pkg Install the AU and VST3 into /Library/Audio/Plug-Ins (you can untick either).
MinervaSpaceEcho-macOS.zip Copy the plug-in bundles by hand.

For the newest build from any branch (newer than the last release, less tested), open the repository’s Actions tab, pick a green build run and download the MinervaSpaceEcho-macOS artifact (you need to be signed in to GitHub; its files have the version in their names).

With the installer

Double-click the .pkg and follow the steps.

NoteIf macOS won’t open it

Builds that aren’t signed with an Apple Developer ID are blocked the first time. Open System Settings → Privacy & Security, scroll down and click Open Anyway, then run the installer again.

By hand

Unzip the .zip, then in Terminal, from the unzipped folder:

cp -R "MINERVA Space Echo.component" ~/Library/Audio/Plug-Ins/Components/
cp -R "MINERVA Space Echo.vst3"      ~/Library/Audio/Plug-Ins/VST3/
# Remove the download quarantine (needed for builds without Developer ID signing):
xattr -dr com.apple.quarantine ~/Library/Audio/Plug-Ins/Components/"MINERVA Space Echo.component"
xattr -dr com.apple.quarantine ~/Library/Audio/Plug-Ins/VST3/"MINERVA Space Echo.vst3"

Set up Live

  1. Live → Settings → Plug-Ins.
  2. Turn on Use Audio Units v2 and/or Use VST3 Plug-In System Folders.
  3. Click Rescan.
  4. In the browser, under Plug-Ins → CrumpLab, you’ll find MINERVA Space Echo.
TipAU or VST3?

They sound identical. Use the VST3 if you want to trigger actions with MIDI notes from a clip (MIDI and automation); hosts don’t send notes to AU audio effects. Everything else, including MIDI-mapping the parameters, works in both.

Build it yourself

You need Xcode’s command-line tools and CMake 3.22 or later (brew install cmake ninja):

git clone https://github.com/CrumpLab/MinervaSpaceEcho.git
cd MinervaSpaceEcho
cmake -S . -B build -G Ninja -DCMAKE_BUILD_TYPE=Release -DMSE_COPY_PLUGIN_AFTER_BUILD=ON
cmake --build build
ctest --test-dir build

The first configure downloads JUCE and Catch2. MSE_COPY_PLUGIN_AFTER_BUILD=ON installs the AU and VST3 into ~/Library/Audio/Plug-Ins for you. See Development for more.

Uninstall

Delete MINERVA Space Echo.component from /Library/Audio/Plug-Ins/Components (or ~/Library/Audio/Plug-Ins/Components) and MINERVA Space Echo.vst3 from the matching VST3 folder. Your presets and saved memories are in ~/Music/MINERVA Space Echo.
