Delay after hitting play before playback starts?

On this current project, I have about 5 audio files each with 2-3 simple Sonitus plugins. No softsynths or anything. My performance bar is VERY light, with almost no activity in the CPU meters, and memory usage is very low.

But when I press play, there is an annoying delay before playback starts. What's going on? This shouldn't be happening with the specs that I have... it should be instant

    I've been noticing this myself. Don't know what is causing it. I have no virus software, internet, firewalls etc. running. I make sure to turn off everything possible. Sonar keeps white screening everytime I close it. I haven't had time to contact Cakewalk yet on that. since it happens everytime they should be able to determin whats causing it.

    Does this happen every time you hit play? My system does this every time I have let it sit idle for a while. I don't know the amount of time, but I want to say leaving it idle for 10 minutes or so makes it act the way you have described.

    The same thing is happening with me too. I have maybe 10 tracks, mostly soft synths. There are a handful of effects on the busses. Before upgrading to X2, I could run projects like this in 8.5 with no problems. The delay after hitting play only happens sometimes. I haven't paid enough attention to notice a pattern.

    Sounds like latency to me - what are your driver settings?

    What happens if you disable ALL Fx?

    If it's all projects it's usually the symptoms of a driver issue.

    Happens to me if I use my interface's latest driver. All earlier versions are fine. I assume it's a driver bug in my case.

    are you sure you don't have the metronome muted but the metronome set for 1 measure of count in? This could account for a measure of silence before the project starts.

    I make some videos. This one shows how to do a physical loopback on the RME UCX to get many more equalizer nodes.

    This is due to many variables like you rPC, your sound card drivers, your sound card driver settings and the project.
    I have 60 plus track projects that do not do this, so i imagine its one or two or all the above items i listed.

    Definitely check the audio interface drivers. And check the Driver Mode in SONAR as well. SONAR prefers ASIO usually. But sometimes WDM works better. Don't use MME

    I found this happens if you have the asio set at 512. If you push it up to 2048 does it still happen. You only need low latency if you are recording?

    It doesn't happen when my ASIO buffer is set to 512. 

    This problem is specific to his drivers, driver settings, PC and project.

    I had the same issue.  Upgraded to X2 from X1 and noticed this issue when I used Diminsion Pro on a track.  As soon as I "froze" the synth, the problem resolved itself and the project would play as normal as soon as I hit the spacebar.  Also tried setting my ASIO buffer to 512, didn't have any affect this time, but great advice all the same!  On big mixes, it helps for me to sometimes shut down ALL windows services under the "MSCONFIG" command...

    Have you pressed the "Pause|Break" key lately? I have inadvertantly pressed that key while using SONAR and the playback gets delayed (and the Now Time line becomes jerky). Pressing the key again and everything is back to normal. Supposedly, there is some performance reason for using that particular key command when using SONAR, but in my experience it only degrades performance.

    Cheers,

    Pressing the Pause key toggles a feature that takes processing power away from the graphics display and lends it to the audio engine. This is supposed to improve playback performance on older systems. Not sure if it's really needed today with the power we now have in our PCs.

    Setting an ASIO buffer to a high setting of 512 inst the answer. If anything the ASIO buffer needs to be at its lowest setting possible. 

    From what i'm quoting you, it seems like your PC cannot handle it, if you need to shut down ALL window services, in conjunction with your driver settings and the quality of the driver that is written (coded) for your sound card.

    Hi vaultvit,
    I had the same occurrence with my saffire pro 40.
    This delay has disappeared with the last driver update
    for the saffire (3.0).
    I guess, Focusrite is working on it.
    Often Matt- Focusrite, a forum member, joins in in such cases.
    If you have not done it, I would recommend you to contact focusrite´s customer support, 
    they are OK.
    regards
