Show HN: Macros with a Behringer FCB1010 MIDI Pedalboard in macOS

A developer created fcbnerd, a command-line tool that lets users control their Mac using a MIDI foot controller (like the Behringer FCB1010) by executing shell commands or outputting JSON events based on footswitch and pedal inputs. The tool works with any CoreMIDI source and is designed as a command-line utility rather than a sandboxed app to allow greater flexibility in triggering actions without permission restrictions.
