PT10 - 23 samples of difference between recorded click playing back from out 8 back to In 8 and the NEWLY recorded click track ... all sample rates and all buffer settings with ADC ON or OFF - So, i am not right on as you say your system is ... odd ...

PT11 - same with ADC off ... with ADC ON it is 4118 samples

does that sound consistant ???

cheers

I am running the Trial of PT11 .. sorry needed to add this

in the past, the differences would also vary depending on what protocol you used. so adat i/o would be different than analog which would be different from spidf. so might give that a look as well.

yep...sounds like issues that we reported in PT9...with the 002 at that

Thanks John

OK so I think we're in the same boat, although your sync is bit worse than mine.

I took another look at my session and actually I also have a small discrepancy between the original click and the new one with delay compensation off - which is 4 samples.

Something is clearly amiss with the delay compensation in PT11.

Out of interest what sample rate were you running at?

For what it's worth, I performed the test mentioned by miketeachesclass in post #31 exactly as described.

I'm on Windows 8 and I am working at 96kHz.

PT 10.3.6 HD Native
With Delay Compensation off: recording is 45 samples late at 96kHz
With Delay Compensation on: recording is 22 samples late at 96kHz

PT 11.0.1 HD Native
With Delay Compensation off: recording is 45 samples late at 96kHz
With Delay Compensation on: recording is 22 samples late at 96kHz

I get no difference between 10 and 11, but in no situation is the recording perfectly aligned as others have described. Does it look like I'm doing something wrong?

mykhal I know you have a similar system to mine ... are your results similar?

actually i have not performed the test with my HD Native gear. since we have the I/O setting available to HD hardware where we can choose to compensate input and output after record pass, i just have not taken the time. if time permits i'll do it today when i'm in the studio...

I might have time to do it in a bit. If so, I will post it.

kool...do you still have your RME gear? or any gear with ASIO drivers?

I tested my HDN and what you are NOT doing is
Open up setup > I/O > input > check "compensate for input delays after record pass:

on my tests
44.1 is 1 sample late
96k is perfect.
buffer size or latency compensation does not change the results.

What did you mean by shutting the adc off in 11?? you cant just turn it on and off like previous versions of PT

Only thing I have left besides the HDN is the Eleven rack.

1) Create a click track and route it to a bus.

3) Mute the click track
4) Run the audio track with recorded click out a hardware output.
5) Patch the hardware output directly to a hardware input
6) Record the audio coming back to the hardware input. (Muting the record enabled track to eliminate feedback, depending on your routing scheme)

So, the path should be:

Audio Track > Output 1 [or any other output] > Input 1 [or any other input] > new audio track

Compare the audio on the freshly recorded audio track to the one you sent to the hardware output. They should be aligned.

Remember in 11, just create the click
