Field notes
The command-line workflow uses cava for audio analysis and can start in the background, including at login through launchd or systemd. ZSA layouts are selected using the name Keymapp reports, while OpenRGB supplies layouts for supported keyboards; other boards can use a manually completed text map. The page says macOS needs a loopback device such as BlackHole, and describes a separate Pro desktop app as a waitlist offering.
