What exactly is the benefit of having Latency adjustment slider in the EXT EFX slot?

This is new to me as I’ve just recently setup the EXT EFX send/return bus in WL 12 Pro. Using my Motu M6 interface with buffer size set to 64 samples I get 4.694 ms and I see I can increase this ms range to 250 ms. Why would I do this?

64 samples as buffer size is really not recommended for WaveLab. Rather use 256 or 512.

Understood. But why wouldn’t I just change the sample count in the interface?

What ‘count’ do you mean?

In my each of my interfaces there is a drop down menu that lets me change the buffer size, from 16/32/64/ etc. to 4096. When I run into glitches or audio problems I open the interface control panel and change the buffer (sample count) size. Of course, since a higher buffer size in the interface creates more (ms) latency within the EXT EX connection, I am thinking I don’t need the adjustable slider that your EXT FX offers.

Is changing the interface buffer size a different result than what your ms Latency slider creates?

There is an indirect dependency.
