Show HN: Macros with a Behringer FCB1010 MIDI Pedalboard in macOS
Why a command-line tool instead of an app Anything that acts on your Mac, like pressing keys or running scripts, needs permissions that sandboxed apps can't get, and every user wants a different set of actions anyway. fcbnerd only reads MIDI, which needs no permissions. The actions belong to your shell, or to a tool that already has the access, such as Hammerspoon or Keyboard Maestro. It follows hotplug: unplug the interface mid-set and plug it back in, and the stream carries on with disconnected / connected lines. list prints the sources available right now. simulate publishes a virtual MIDI source named fcbnerd simulator that plays synthetic presses, a pedal sweep and a sysex message on a loop.
