MPVST — audio effects and instruments as a VST3 plug-in.

Get the archive for your platform from the latest release; each comes with a .sha256 to check it against.

# Windows: installs for you alone, so there is no administrator prompt
MPVST-0.3.0-windows-x86_64-setup.exe

# Linux: copies the bundle to ~/.vst3
tar xf MPVST-0.3.0-linux-x86_64.tar.gz
./install.sh               # in the unpacked folder

Then rescan plug-ins in your DAW, and make it a real rescan, not a restart: hosts cache what they found last time. The installers are not code signed, so Windows SmartScreen warns the first time. REAPER is the only DAW tested.

Search your FX browser for TR-808, Minimoog or Tape Delay and drop it on a track. Every instrument in audioinstruments and effect in audioeffects shows up under its own name and category. Its editor has a patch selector, a bypass switch, a status light and a slider per macro. The two MPVST Script Host entries run a script you point them at, and stay silent until you do.

A composer project renders to audio without a DAW, and a script's own macro defaults survive a project reload. The composer guide shows how to write a song as Python and render it, or turn it into a REAPER project.
