Latency of Virtual Instruments During Record

[erant1]

Hi -

I'm running an HD-3 system on an eight core MacPro. Stable, no crashes. I've noted, however, that in recording any virtual instruments - Strike, Structure, Hybrid or Xpand - there's extreme latency of audio on the virtual instrument track during the time I'm recording. This latency is gone upon playback of the track afterwards, but of course it makes accurate recording nearly impossible, and I have to do a lot of MIDI editing to fix the timing errors. Is this an issue with a system setting in Preferences? I usually leave these at the "suggested" settings.

I should also add that there's absolutely no latency whatsoever in recording audio tracks.

Thanks in advance for anyone's assistance!

Hi,

Have you got delay compensation (ADC) turned on? this will cause noticeable latency when playing live! as you are playing against data that is being moved in time during playback to compensate for any plugins in the session, especially worsened if there are plugins on the mix bus and master fader. Also RTAS plugins will cause more latency issues than TDM plugs!!

You could try just disabling ADC on the track with the virtual instrument on. command+control+click on the delay compensation numbers on the track to disable ADC and see if that helps.

Its a complicated subject that could go on for 10 pages. all depends a lot on what stage of the mix you are at? if you are deep into the mix with many plugins and you then want to play along with the session in real time, then its going to be difficult with the ADC turned on as their will be more latency caused by more plugins etc.

So you can sometimes just temporarily disable plugins that cause large delay and write/record any new parts then enable them again afterwards etc. or you can even just print the mix to stereo audio and work to that, and probably another 3-4 suggestions will come from other users as to how they work around it.

Thank you so much for the quick response. I'm out of my studio now until this evening, but will give it a try. That is the only setting I didn't change - I altered all of the buffers and DAE settings, but to no avail. I bet this is it.

Thanks again,
