# USB MIDI device hotplug rules for Raspberry Pi RT Audio Mixer
|
|
#
|
|
# These rules:
|
|
# 1. Give the 'audio' group read/write access to USB MIDI devices
|
|
# 2. Create a persistent symlink for known controllers
|
|
# 3. Trigger systemd service reload on hotplug
|
|
# 4. Set nice/rtprio for MIDI processing threads
|
|
#
|
|
# Install: sudo cp config/99-midi.rules /etc/udev/rules.d/
|
|
# Reload: sudo udevadm control --reload-rules && sudo udevadm trigger
