Be careful with resource-heavy plugins while tracking

[Steenamaroo]

I’m not sure I understand - what do you mean tracking & monitoring through a plugin? I put a series of plugins on a vocal track - EQ -Tube EQ - Exciter - 2 Compressors , DeEsser etc.. Then I buss to a Compressor track and a Reverb Track - I am using Logic Pro - there is no noticeable latency in my setup - I also have Drums with various Plugins, Guitars, Bass,Synths etc... with Various plugins (Like Helix Native) etc…they all run with no noticeable latency - I have my I/O buffer size set to 64 Samples -

Unless I’m mistaken this is more resource heavy than just a UA Preamp and LA2A - so maybe there is something mixed up in your system?

There's two different scenarios. One is a problem and the other shouldn't be.
Say your mix has plugins which introduce latency so what you hear, and perform to when doing overdubs, is late.
This shouldn't be an issue. Many DAWs compensate for this.
They know the backing you're hearing was 1024 late, so they delay that vocal by the same amount to make things right in the mix.

If there are tracks in your mix with plugin delay of 1000, 600, and 200 ms,
the daw should delay those by 0,400,800, so everything's late but correct.

The problem comes, for example, if there's some plugin on your vocal track introducing a half second latency and you need to hear your self while you record.
That's where you're going to need to disable the offending effects, or set up a monitoring bus for your input that has these-will-do low latency plugins, just for nice monitoring,
or use real-time monitoring and accept that what you hear will be dry whilst recording.
