Connection info: model, name, IP, firmware, guardrail limits and change count.

Whole-board summary: every input with source, preamp gain/phantom, HPF, fader, mute, LR assign and active sends; buses, FX sends and returns, main LR and DCAs. Start here.

Every setting of one strip (channel, aux, FX return, bus, FX send, LR or DCA) as shown by the mixer: config, preamp, gate, compressor, EQ bands, fader, sends, groups.

Find strips whose name contains the query (case-insensitive). Empty query lists all named strips.

Set a fader (channel, aux, FX return, bus, FX send, main LR or DCA). Give db (absolute, -inf..+10) or delta_db (relative, e.g. -3).

Mute (muted=true) or unmute (muted=false) one or more strips.

Set the send level from a channel/aux/FX return to a bus (bus1-6, monitor mixes) or FX send (fxsend1-4). Give db or delta_db, and optionally the tap point (PRE = pre-fader, usual for monitors).

Parametric EQ. Channels/aux/FX returns have bands 1-4, buses and LR 1-6. Gain -15..+15 dB, freq 20..20000 Hz, Q 0.3..10. on=true/false (without band) switches the whole EQ.

Channel high-pass (low-cut) filter, 20..400 Hz. Setting freq_hz also switches it on unless on=false.

Channel noise gate / expander. threshold -80..0 dB, range 3..60 dB, attack 0..120 ms, hold 0.02..2000 ms, release 5..4000 ms.

Compressor on a channel, bus or main LR. threshold -60..0 dB, ratio 1.1..100 (snaps to 1.1/1.3/1.5/2/2.5/3/4/5/7/10/20/100), knee 0..5, makeup 0..24 dB, attack 0..120 ms, release 5..4000 ms, mix 0..100 %.

Mic preamp of a channel: gain -12..+60 dB (absolute or delta), 48 V phantom power, polarity invert. Phantom changes always need confirmation.

Apply several changes at once as ONE undo step, e.g. rebalancing a monitor mix: [{target:'click', param:'send.level', dest:'bus2', delta:3}, {target:'bass', param:'send.level', dest:'bus2', delta:-2}].

Set up many input channels from an input list / stage plot in one go (one undo step): names, colours, HPF, preamp gain, phantom, USB source, LR assign, fader, pan.

Build a monitor / in-ear mix on a bus in one step: sends = {source: dB} (e.g. {'vocal': 0, 'guitar': -6, 'click': -3}); sources not listed are left unchanged. Sets the tap point (default PRE-fader) for the listed sources, and optionally the bus name, colour and master fader.

Measure live levels for a few seconds (peak and average dBFS, 0 = clipping). scope 'channels' = channel strips, FX returns, buses, main LR; 'inputs' = raw mic/aux/USB inputs. Flags clipping, hot, low and silent signals.

Gain-staging helper. Ask the musicians to play their LOUDEST part first, then run this. Measures channel peaks and suggests preamp gain changes to reach target_peak_db (default -12 dBFS). Suggests only - apply with set_preamp.

Save the whole board (all channel, bus, FX, routing and preamp settings) to presets/.json. Use names like 'song-3' or 'band-X-2026-09'. Overwrites a preset with the same name.

List saved board presets (newest first).

Show what differs between a saved preset and the current board (or another preset given as other). Answers 'what changed since ...'.

Restore a saved preset to the mixer (only differing parameters are written). Always needs confirm; the current board is auto-saved first and the load is one undo step.

List the mixer's internal snapshots (slots 1-64) that have a name.

Save the current board into the mixer's internal snapshot slot 1-64 with a name (max 12 chars). Overwriting a named slot needs confirm.

Load one of the mixer's internal snapshots (changes the whole board). Always needs confirm; the current board is auto-saved as a preset first so it can be restored with load_preset.

Revert the last change group(s) made through this assistant (restores the exact previous values).

Changes made through this assistant in this session, newest first.

Read any OSC address (e.g. /ch/01/eq/2/f) - returns the raw value and the mixer's own text readout. Escape hatch for settings the other tools don't cover.

Write a RAW OSC value (normalized 0..1 floats for levels/frequencies, ints for switches/enums, text for names). Prefer the dedicated tools. Guardrails still apply; system paths need confirm.
