How to fix latency of VST plugin?

MuLab does not yet support APDC. The only way of compensating for plugin delays is to insert the relevant delays manually. The principle is: If VST plug X has a delay of N samples the you need to delay all other signals with N samples before mixing it with VST plug X. The module that is ideal for this is the Pure Delay module as you can set it to a sample precise delay.

It's a very odd thing.
Because "Plugin window > Options > Show Info > Initial Delay" have the latency parameter.
So mulabe can recognise the latency, then only add a certain delay to other buses...

It may seem simple, but it's less simple to implement than it seems. Anyway it's on the wishlist to add APDC.

And I noticed Pure Delay does not have "Process On/Off" button.
So I can't off it from the Rack view, I have to "Delete" and re-Insert it.

Indeed that module can use an on/off button too. Taken note.

Think outside the rack idiom and in the modular idiom and you'll see why it's less obvious - there can be multiple paths into and out of every module and of course some of the inputs to a module may also directly feed into some of the outputs of that module - directly or indirectly via other modules. And every one of those may have an amount of delay that needs to be taken into account.

How does this sound?

You're aiming to align outputs that hit the same audio out. You can find a Rack that has an audio out as its output. Then each rack that feeds that rack as its output (not sends) would have its overall delay measured and adjusted so they aligned. Then you find any other Racks with the same audio out and, if found, similarly ensure they're all compensated just before the output. (Then repeat for any other audio outs.) (Maybe have an option to align regardless of "same out" or not.)

You'd not need to look into any module (other than a Mixing Desk Rack) and this would only affect MuLab, not MuX.

Yes.
It's what I want.

Can someone provide a typical scenario for this. I think I understand it, but still a little unsure.

Edit VST Initial Delay setting is not saved with presets...
