Standalone, VST3 and Audio Unit. Internet required for rendering.
This beta is unsigned while Apple signing is in progress. After downloading, run this in Terminal to remove the installer’s quarantine flag:
xattr -d com.apple.quarantine ~/Downloads/midi-audio-macos-arm64.pkg
Use the actual path if you renamed or moved the download. “No such xattr” means the flag is already absent.
Import MIDI, choose an instrument and render. Drag the rendered waveform into your session. REAPER VST3 can also read the selected MIDI track directly.
