Hello everybody,
 
I've got an unusuall problem with my mix, i've never faced something like this before. I've been getting delayed Send signals everytime i enable them, even to a bus that has no plugin. Its like the track has a double and the 2nd is delayed for half a second. its wierd that it happens on some tracks, not all of them. and sometimes, it happens only to the 2nd send in the signal chain. It sounds exactly like a bad latency you can easily get mad at.
 
I dont know if all of you can understand the situation, but if someone has experienced it, they sure know what i'm talking about.
 
Peace,
Yusuf

First, I would check your ASIO buffers or WDM slider and maybe lower them. Actually check all your sound card settings. Your buffer in Que should be at 2 and never moved. Your Playback I/O and Record I/O should be set from 128 to 512 and always use increments of 64.

If that doesn't work, make a new track and move the clips to that track. Maybe those tracks got corrupted some how


Thanks,

thanks Cj,

I've done about everything you suggested, but i still got the same problem.

I got my ASIO buffer set at 221samples, and i got the rest like you said.

however i will show you some latency reports, i dont know if they can tell you anything.

ASIO report latencies

Input: 10.9msec, 482samples
output: 15.9msec, 703samples
roundtrip: 26.9msec, 1185samples

Those numbers look healthy to you?

what perticulair plug ins are giving you the problems?
some sonar plug ins are look ahead plug ins which are very taxing on the cpu.
there is a button in control bar to help combat this I believe its called LPC,click it

I was going to mention this but wasn't sure if it applied to dry sends. It is not by default in the Control bar but is in the Control Bar Mix Module (right click the Control Bar and select Mix Module until it appears). I think the button is label PDC or something. I never really understood it until recently because Sonar automatically handles plug in latency which brings me to my next point. Somewhere in the Edit>Preferences menu is the setting that allows Sonar to automatically handle this type of latency. I forget where it is but it is all detailed in the manual so check that out. SHould be in the index under Input or Plug In latency. I can dig it up if necessary but I'm currently in the middle of something. Cheers.

Some plugs, like Charlie mentioned, can cause latency. The LP64 eq or other plugs like that can definitly cause your issue. Those plugs are meant for the master bus.

What you can do is try disabling plug ins until you find the culprit. Just click that blue button to disable a plug.

I agree with Beepster, make sure the plug-in delay compensation is enabled. It is the button labeled PDC in the tool bar. If it's not there right click in the tool bar and select mix module.

appreciate the reponses.

PDC works like magic. However, i still have to do some study of how this PDC works, whether it's working with a side effect of somekind. Strangely enough, the delay doesnt happen when i disable PDC, but when i bypass and unbypass the affected Send, the delay comes back. I guess i just have to leave the PDC on.

I still cant find the culprit, i took out all prochannel plugins, and leave all low taxing plugins working. My project isnt that big at all, only about 9 tracks, 5 busses.

However there's something thats contradicting what i understand, should i set a higher buffer setting or a lower one in my situation? Because from what i understand, higher buffer settings are better when mixing..

Try turning PDC off globally. If the timing problem disappears, then you have a plugin that's causing it. Perhaps a plugin that is not reporting its internal latency correctly.

And no, raising your buffers will probably not help with this particular problem. You only need to do that if you're getting dropouts while mixing.

thanks for the correction people..pdc,  :)
