VST3 & Audio Unit · macOS

Five plug-ins for macOS,
as VST3 and Audio Unit.

Three of these began life as Cakewalk DXi plug-ins written in Visual C++ 6 between 2003 and 2004, and have been ported to macOS from their own sources rather than reimplemented from their behaviour — the DSP carried over sample for sample except where a deviation is deliberate and written down. Two are new work on the same template.

Each one builds a .vst3 and a .component from a single CMake project, so there is one set of sources and one DSP behind both formats.

Universal 2 · Apple Silicon and Intel · signed with a Developer ID and notarised · macOS 10.13 or later

Installing

Every plug-in ships as a single signed, notarised .pkg. Open it and the installer offers the two formats separately, so you can take the VST3, the Audio Unit, or both:

Quit your DAW before installing — a running host holds the old copy open. Logic rescans Audio Units on its next launch; to force it, quit Logic and run killall -9 AudioComponentRegistrar.

Formats and hosts

The Audio Unit is Steinberg's AUv2 wrapper around the same VST3 bundle, so the two cannot drift apart. Both have been run through Steinberg's validator and Apple's auval. The instruments appear as aumu and the effects as aufx, all under the manufacturer code AECo.
