A known-good channel, carried from one gig to the next.

In the library, pick the channel to capture, give it a name, and save. You can file it under a family — Vocals, Drums, Guitars — which groups it beside the factory templates for the same family in the picker. Naming no family is a choice rather than a missing field: it lands as an ungrouped entry.

The library is sorted by name, never by date. A config library is something you browse for the chain you want, not something you replay in the order you made it.

What a save captures:

• The EQ, the gate and the compressor.
• The insert rack and the order the processing runs in.
• Digital gain, trim and pan.
• Phantom, pad and head-amp gain.
• Polarity, and the alignment delay with what it is aligned against.

And what it deliberately does not:

• The fader, the mute, the solo and solo-safe.
• The channel’s name, its colour and its instrument.
• Recall safe, and whether the channel is armed to record.
• Every send to every bus.
• What is patched into the channel, and what the channel is linked to.

A config says what this channel’s processing is. It says nothing about where the channel is patched, how loud it sits in the mix, or what it is called — those belong to the show, and they are what a session saves.

Applying a config is not additive, so before it lands the console asks the desk what would actually change and shows you the answer:

Apply “FOH Vocal Capture”?

A config is a whole statement about a channel, so applying it will move what CH3 holds now:

• Gain −6.0 dB → 0.0 dB
• Trim −8.0 dB → 0.0 dB
• Pan 0.60 → 0.00
• EQ replaced
• Insert chain replaced

The list is one line per field that would move, computed by the console against what the channel holds at that moment — never by the surface, so what you are shown and what the door will do cannot disagree. A fact that rides several fields is listed field by field: you are warned about the 48 V, not about “the head amp”.

Three things read differently on purpose. A structured fact — an EQ curve, a gate, an insert rack — says replaced rather than printing a before and an after, because “from 8 bands to 8 bands” is not a readable sentence. A dash means the desk does not know what is there now, which happens on a head-amp fact from a preamp that has never reported; unknown is not zero. And a config applied to a channel that already matches it moves nothing, so it applies on one tap with no dialog at all — applying the same config twice must not ask twice.

The warning can be turned off with Don’t warn me again, which is a console-wide setting of its own. It is deliberately not the same switch as the one that arms destructive actions: an apply removes nothing, and an operator who turned off delete-arming did not ask to lose this.

Every way into an apply obeys it — the instrument picker on the processing view and the Apply button in the library both ask the same question. Cancelling leaves both doors shut, so a channel is never labelled with a template it did not get.

The question is asked by the console, not by the screen you happen to be using. An apply that would move something is refused at the door and comes back carrying the same list of moves, and nothing is written until the apply is sent again saying, in so many words, go ahead. That is why the dialog you see is not a screen the browser invented: the button fires, the console refuses, and the refusal is what the dialog is drawn from.

applying this would move 5 of what the channel holds (gain, trim, pan, eq, inserts) — confirm to go ahead

An OSC surface and an MCP client meet exactly the same refusal, with the same list, and answer it the same way. There is no client that quietly applies without asking, and no client that has to be taught the rule: the desk holds it, in one place, and every surface renders what the desk said.

Both the sign-off setting and the list of moves are read afresh on every attempt. Turning the warning off takes effect on the next apply rather than on the next reload, and a console that cannot read its own setting asks rather than assumes.
