💖 X42-FIL4 — the manual, but make it cute 💖

okay bestie, welcome to the x42-fil4(1) user-commands page, except I'm the one explaining it to you now. it's a JACK Parametric Equalizer, and yes it's as iconic as it sounds. buckle up. 🎀

✨ NAME ✨

x42-fil4 — x42 JACK Parametric Equalizer 🦋

🌸 SYNOPSIS 🌸

x42-fil4 [ OPTIONS ] [ Plugin-ID or URI ]

that's it. that's the whole vibe. options first, plugin last. 💅

👑 DESCRIPTION 👑

x42-fil4 — JACK Parametric EQ. no cap.

so here's the tea: this is a standalone JACK application built out of a whole collection of LV2 plugins. it's giving "greatest hits album" energy, fr fr.

wanna see the whole lineup? use ID -1, or -l, or --list for a dedicated list of all the included plugins. and by default? it just grabs the first listed plugin (ID 0) and runs with it. main character behavior honestly. ✨

List of available plugins: (ID "Name" URI)

Usage: literally every control element is operated with the mouse. your hands are staying on that mouse, bestie 🖱️💖

  • Click+Drag — left/down = decrease, right/up = increase the value. hold the Ctrl key and it gets more sensitive. careful, she's reactive.
  • Shift+Click — resets back to the default value. the undo button of your dreams 🫶
  • Scroll-wheel — up/down by 1 step, which is the smallest possible adjustment for whatever setting you're on. and if you scroll rapidly and continuously? the step-size grows. it's matching your energy, honestly. 🔥

oh and when you're done? you can close the whole thing by sending a SIGTERM (that's CTRL+C on the command-line, bestie) or by just closing the window. either one. no drama. 🌈

💅 OPTIONS 💅

  • -h, --help — displays this help and dips out. short and sweet. 💖
  • -j, --jack-name <name> — sets the JACK client name (defaults to the plugin-name, in case you were wondering).
  • -G, --nogui — runs headless. super useful for OSC remote ctrl, iykyk. ✨
  • -l, --list — prints the list of available plugins and exits. window shopping, but make it a command.
  • -O <port>, --osc <port> — listens for OSC messages on the given UDP port. 📡
  • -p <idx>:<val>, --port <idx>:<val> — sets the initial value for the given control port. pre-setting the vibe before the party starts.
  • -P, --portlist — prints the control port list on startup. receipts, immediately.
  • --osc-doc — prints all the available OSC commands and exits. the lore, documented. 📜
  • -V, --version — prints version info and exits. who are you, really.
