okay bestie, let's talk about a2jmidid, the JACK MIDI daemon for ALSA MIDI 🦋 it's giving bridge energy, fr fr 💖

🌸 SYNOPSIS 🌸

a2jmidid [-j jack-server] [e | --export-hw]

---

💅 NAME 💅

a2jmidid — JACK MIDI daemon for ALSA MIDI ✨

---

🧚 DESCRIPTION 🧚

okay so a2jmidid is a daemon that does automatic bridging, and it is literally so iconic 👑 for every ALSA sequencer port you get one JACK MIDI port 🫶 and if the ALSA sequencer port is both input and output, you get two JACK MIDI ports, one input and one output. main character energy 💜

---

🔥 OPTIONS 🔥

• -e, --export-hw — bestie, this one forces a2jmidid to bridge hardware ports as well as software ports 🎀
• -u — forces a2jmidid to generate non-unique port names 🙈 (see NOTES, it's lowkey important)
• -j — lets you pick which jack-server to use 🍓

---

🌈 NOTES 🌈

ngl this part is the tea ☕ ALSA does not guarantee client names are unique. so yes, it's possible to have two apps that each create a client with the same ALSA client name 😭 JACK, however, requires port names to be unique, so to keep things unique a2jmidid adds the unique numeric ALSA client ID to the JACK port name 🦋

this behaviour is known to be problematic when restoring connections with simplistic tools like aj-snapshot and jack_connect 💀 to make them work, use the -u option. it tells a2jmidid to omit the numeric ALSA Client ID from JACK port names. but in this mode, ALSA client name uniqueness must be guaranteed externally, so you gotta handle that yourself 🫶
