Does apollo preamps introduce modulation?

While recording

Sometimes i find modulations happen in the recorded audio...when using uad preamps

Why does this happen?

What type of modulation?

I dont know what to say but it slightly introduces some kind of phasing or chorus sounds, for a very short period(maybe less than 0.5 second)

First i thought it was my problem but after i tried hardware preamp, i found that weird modulationtic something doesnt happen.

So i am suspecting... maybe preamp plugin can go wrong.

But it is just guess, so i am wondering

"Do others also hear modulations while working with preamp plugin"

This could be comb filtering caused by latency. With your DAW closed try 96kHz and then try again at 44kHz. Is the latter worse?

Do you have anything in the Unison slot?

Well i am not expert at recording and also not a english familiar guy...so apology for potential miscommunication

1) well most of the time i dont notice problems while recording. I find those while monitoring... i am not currently in front of my studio but i will try.

2) i always have neve preamp or manley preamp on unison, and cl1b on insert, 224 on aux.

That sounds like you're being affected by comb filtering caused by the acoustic sound resonating through your skull and also reaching your ears blending with the slightly delayed sound coming from Apollo. For the people who are sensitive to this, the phenomenon improves once you're below 2ms RTL.

Unison preamps add 55 samples of latency. Hardware preamps do not.
 
What do you mean by that? Is it while playing back your recorded tracks?
Or did you mean monitoring while recording?

You are direct monitoring all the time, means no software monitoring?
I mean playing back recorded track on daw.

I dont notice any problems while i sing(maybe it is because modulation problem is so subtle)

But when i play that recorded audios on ableton i start to notice problems.

Hmm thanks for the reply but what i mean monitoring is...

I find problems when i play recorded audios on the Daw.

I mean.. i dont notice problems while singing. Audio coming through my headphones sounds fine.

In this case, am i affected by comb filtering?

Thanks

No, I doubt that.

For potential help we could need some more information.
What we know:
1. You experience phasing while you are playing back your recording
2. recording and monitoring while recording is fine
Right?

I assume the playback always involves several tracks, at least 2 in any case?

Is the experienced phasing dependent on the pitch, could you narrow it down somehow?

How are your recordings exactly?
Do you have single mono instruments, stereo tracks? Are those acoustic instruments or VST instruments?

If you zoom into your wave forms and compare different tracks, do you notice different starting points of the waves?
Maybe they are a couple of samples behind on some tracks, which will result in those phasing issues.
