Help with some vocal latency/chorus sound!

    Hey all,

    I have been having a problem getting rid of this vocal latency issue in PT 9. It sounds like there is a chorus effect on it or that the voice is being doubled when I am just arm it for recording. I don't ever remember having this problem before PT 9 but I may just not have noticed. It is not the HD PT. I am running on a Mac Pro 2.8Ghz 8 core with osx 10.6.8 and 4GB of ram. PT is version 9.03. My interface is the Onyx 1640 mixer via the firewire 400 attachment. H/W buffer size is 128 samples, and if i go any lower there is this weird distortion.(not sure if that's normal either) Host processors reads 4 processors, DAE playback buffer is at level 1, and Delay compensation engine is set to none.

    Is it normal to have this weird sound just monitoring vocals. A lot of tips i've seen on youtube were pretty much to mute the vocal track and record with one headphone off. I can't do that when i'm tracking a band together, where the rest of the band needs to hear the vocalist.

    Any tips in reducing latency would be appreciated by this poor noob!

    It sounds like you are getting the signal from the mic by two different paths, one of which is Pro Tools' input monitoring and the other is probably an analog path through the board. Find a way to switch one off.

    Thanks. When i monitor only through the mixer it sounds as it should, however when i switch from the the mixer to the firewire option on the mixer it still has the chorus effect on it. The problem is only occurring through PT. I may have to call mackie or Avid to see what they suggest if i can't figure it out. Any other suggestions?

    thanks a lot!

    I would find a way to mute Pro Tools' input monitoring and just use the Mackie's analog path. It may be as simple as muting the track you're recording to or it may involve some clever routing. On a Digi 002R/Mackie mixer setup I resorted to using the 7/8 output rather than the L/R monitor output for playback to headphones to keep input monitoring from Pro Tools out of the mix. I don't know if you can set your mixer up to function like that.

    Hi there. There is very informative latency tutorial at macprovideo.com that explain the finest points of latency and how to fix them. I believe it was explained through logic, but the principles work with any daw. Also there is a thread from mackie that describes a similar problem, that may be of use to you!

    The problem isn't how to reduce latency, it's how to choose one input monitoring path rather than two.

    When you figure this out remember that you might actually find a use for this some day!

    As much as I love plug-ins I like finding/creating my own effects. I'm a dork like that. ;)

    I agree with this.

    I use logic with a focusrite saffire pro 40 audio interface. When recording I monitor through the audio interface. I do this by first switching to 'zero latency mode' on the audio interface then by selecting 'no output' on the channels I am recording in logic.

    If I wanted to monitor through logic, I would select 'daw tracking' on the audio interface and mute the channels I am recording on the audio interface. I would then select 'zero latency mode' in logic and select an output on the channel I am recording in logic.

    Hope this helps
