PortMidi¶
Name: mido.backends.portmidi
Installing¶
The PortMidi backend requires the portmidi
shared library.
apt install libportmidi-dev
brew install portmidi
port install portmidi
The backend will look for:
portmidi.so (Linux)
portmidi.dll (Windows)
portmidi.dynlib (macOS)
Features¶
Can send but doesn’t receive active_sensing
messages.
PortMidi has no callback mechanism, so callbacks are implemented in Python with threads. Each port with a callback has a dedicated thread doing blocking reads from the device.
Due to limitations in PortMidi the port list will not be up-to-date if there are any ports open. (The refresh is implemented by re-initalizing PortMidi which would break any open ports.)
