UAPMD

UAPMD (Ubiquitous Audio Plugin MIDI Device) is a cross-platform, multi-track audio plugin host sequencer that exposes their control points as virtual MIDI 2.0 devices. Your can use arbitrary MIDI 2.0 client apps to:

• play MIDI 2.0 instruments with 32-bit precision; use Assignable Controllers (NRPNs) to change plugin parameters in 32-bit values (velocity in 16-bit).
• retrieve parameter list as Assignable Controllers and presets as Program List, as long as they are exposed via the plugin APIs. Thus you don't have to remember which controller index maps to the parameter you want, or which program number maps to the tone you need.
• save and load the plugin's binary state (.vstpreset etc.), just like how you use them in a DAW.

We also develop midicci, a fully featured MIDI 2.0 software keyboard that leverages the full potential of this project.

uapmd-app, our proof-of-concept sequencer application, and its engine uapmd-engine, is currently capable of:

• managing a master track and multiple tracks, where
  • each track has a linear list of audio plugins, and.
  • contains audio clips and MIDI clips together.
• importing SMF into multiple tracks.
• importing audio file into multiple tracks using STEM separator (Demucs so far).
• save and load them as a project.
• get connected externally for full control using JavaScript, along with MCP server.

UAPMD supports the following platforms:

• Linux desktop: VST3, LV2, CLAP.
• macOS: VST3, AU(v2/v3), LV2, CLAP.
• Windows: VST3, LV2, CLAP.
• Android: AAP.
• iOS: AUv3.
• Web browsers: WebCLAP.

UAPMD availability

UAPMD is an open source project hosted at GitHub so far. Binary packages for Linux (.deb, and .rpm), and Windows are available on the Releases page: https://github.com/atsushieno/uapmd/releases

MacOS .dmg is built there too, but since it is not signed, you might want to use Homebrew ('brew install atsushieno/oss/uapmd'). Likewise, The AAP Project doesn't build and publish iOS version yet.

And Web browser edition is always published at GitHub Pages: https://atsushieno.github.io/uapmd/
