Midi timing - latency compensation

Hello to all!

The last couple of days I did some work with Nuendo 3 involving lots of VSTi synths - I had a lot of time to deal with MIDI - and I observed that all my notes were recorded early!
I know that this is a well-known problem for Nuendo and Cubase SX. So I downloaded the MIDI-Loopback-Test, which recommended me to use the Creamware emulated Midi ports and to have the DirectMusic Timestamp set to ON in Nuendo, which things I did.
I measured again and things were OK, although my Scope Project was getting worse results than the Steingberg midi interface in the Midi-Loopback-Test. But nevermind...

Now.. the problem:.. there is latency, which makes me to play notes earlier (without me noticing it), so they get recorded earlier! When I play back what got recorded, everything is early!

Is there a way to measure and compensate for my tendency to play early the VSTi synths, so that they get recorded at the correct time in Nuendo?

Thanks

there is another thread about this problem (i don't remember where).
The solution was to disable direct draw under the video settings of dxdiag (start/run/dxdiag).
It works for me.

Thank you for replying!

.. but I cannot see how this would help against everyone's tendency to play notes earlier when there is latency..

What I am asking is how can I measure the real latency my system has (sum of AD/DA-VST latency-Kontakt latency-etc etc) so that I can compensate for it?

Hi Rodos

Disable latency compensation and record simultaneously midi going to a synth and the synth audio output. Then look at the difference between note on occurence and beginning of audio from the Synth!

Cheers
