fcbnerd ek command line tool hai jo kisi bhi MIDI foot controller, jaise Behringer FCB1010 ko macOS ke liye extra input device banata hai. Yeh MIDI sources se connect karta hai aur specific footswitch ya pedal messages milne par shell commands chalaata hai ya JSON events output karta hai jise doosre programs process kar sakte hain. FCB1010 ke liye banaya gaya lekin koi bhi Core MIDI source ke saath compatible hai.

Sandbox permissions ko avoid karta hai sirf MIDI read karke, actions ko user ke shell ya tools jaise Hammerspoon ko delegate karta hai. Homebrew se tap trust karke ya Swift se macOS 13+ par source se installation ki ja sakti hai. Users MIDI events jaise control changes ya program changes ko bind kar sakte hain, jaise '1:20:127=open ~/Downloads' patterns use karke actions trigger kar sakte hain.

Tool real-time event streaming, hot-plugging, aur testing ke liye simulated MIDI input ka support karta hai. Output ko text ya JSON format mein format kiya ja sakta hai, taaki readability ya scripting ke liye immediate flushing ke saath pipe compatibility ho. MIDI_TYPE, MIDI_CHANNEL aur MIDI_VALUE jaise environment variables bound commands ko pass karein, jo dynamic responses jaise expression pedals se volume adjust karne mein sakin sakti hain.
