VEP server reporting wrong buffer Size for all DAWs tested

My VEP slave template has 1 instance, 23 Threads (out of 24 threads), 48 midi ports, 48 audio outputs, 4 audio inputs.

I set all the DAWs to 128 ms and the VEP pro plug-in within each DAW is set to 1 x buffer:

- When connecting with DP9, VEP pro 6 server reported a Buffer Size:128, Outputs 48, inputs:32

-When connecting with PT 12.7 HD, VEP pro 6 server reported a Buffer Size:1024, Outputs 48, inputs:32

-When connecting with CB9.0.1, VEP pro 6 server reported Buffer a Size:512, Outputs 48, inputs:32

Any idea why VEP is reading the wrong buffer size for all the DAWs, if i understand correctly, VEP pro 6 server should read 256 ms if the DAWs are set to 128 ms and the plug-ins 1 x buffer as stated above.

Hello Anhtu, 

The latency read-out you get from the slave depends on the latency inducing plug-ins you have inserted in the VE PRO server (automatic delay compensation on playback).

Hi Paul,

Are you saying it's the latency of the plug-ins inserted in the VEP pro server ? If so, since i'm testing the exact same template (same plug-ins inserted), logically shouldn't i get the same latency reading with all DAWs ?

or are you implying the latency of the VEP plug-ins inserted in the DAW ? If that's the case then on the channel where i got VEP inserted in PT, it shows a delay compensation of 128 samples and not 1024, the reading i get from VEP server.

Hello Anhtu, 

I'm referring to the plug-ins inserted in the VE PRO Server. 
I´ll check that tomorrow.  Does it affect your workflow in any way?

I'm evaluating different DAWs and updating our studio for a few big upcoming projects, hence the questions above. To be honest, when i connect to the same VEP template, even though it reported different latency for different DAWs, it ''feels'' pretty well the same to me.

The buffer size reported in the VE Pro Server is the maximum buffer size set by the host. In practice, modern hosts can set a higher buffer size, but actually process in smaller sizes when real-time response is desired. So you indeed shouldn't feel a difference in terms of latency.
