UAD-1 and 64 bit


Hi

I've found that the plugin latency compensation for UAD-1 is not working with the 64 bit version of Sonar. Ten instances of the 1176SE in one FX bin introduces 0.174 seconds of delay, ie 17.4 milliseconds each, which is close to what the UAD control panel reports, 16.4 milliseconds. Just to be sure I've explained this, sending a snare drum off to an FX bus with 10 1174SEs creates a delay of 0.174 seconds. Other 32 bit VST plugins are also creating delays but much shorter.

There is no problem with the same project running in the 32 bit version of Sonar. Things I've tried is change from ASIO to WDM/KS, synchornization settings, with no help.

Windows 7 64 bit, UAD 5.6.0 and Sonar 8.3.1.

Any thoughts appreciated,
Brett

    Well, if I understand your problem, though I don't know why anyone would use 11 instance of the 1176se, this varies widely by your ASIO buffer setting. I am getting 12.8 ms at 256 buffers and it goes to 3.8ms at 64 buffers. Like you the UAD card states it a little less at 11.8ms. When you say there is no problem in 32 bit. What numbers are you seeing in that environment?

    The ten instances is to measure the delay. Plugins aren't supposed to any delay. In the 32 bit version there is no delay at all.

    How are you measuring the delay? What are you referencing in Sonar that leads you to this conclusion?

    I have a track with a snare drum, it has a send to a bus which has all the UAD plugins, I can then measure the time delay between the orginal snare and the sound after it's gone through the bus' fx bin.

    Yes, I understand but what are you using or better yet, where in Sonar are you seeing the time differential? I'm trying to follow your procedure and need to see what you are seeing. I have UAD1 PCI, PCIe and the UAD2 in the same machine. Running 64 bit Sonar as well in Win7. In other words give me a step by step.

    One possible issue. You are probably using Bitbridge for the UAD plugins in 8.3.1. That may account for some latency.

    I sat down to write out exactly what I did and then tested it from the beginning and of course I can't replicate the problem now. The project that I had the problem with still has the problem but if I start a project from scratch I can't replicate the problem. So don't bother trying it yourself, I'm sure you won't have any problem, but thanks for taking an interest.

    A track with a single snare hit,
    - output to Drum Dry bus
    - send to Drum Wet bus

    Drum Dry bus
    - output to Drum Master

    Drum Wet bus
    - FX bin UAD plugins
    - output to Drum Master

    You can hear the delay with only one UAD plugin but as you add more the delay is more obvious. Bouncing to tracks with the option "Busses and Tracks" I measured the time difference between the two wave forms.

    Yeah the only thing close to this I have seen is that if you insert a plug in on a parallel buss while a track is playing you can get phase issues with UAD plug ins. It does not go away if you stop then start the transport. You have to rewind the project so the delay compensation adjusts.

    u can run uad plugins in sonar 64 bit install and win 7 64 bit ?
    i have tried it for a couple month, and i only can run one uad plugin at the same time in this constelation



    what are u doing to use uad in win 7 64 bit and sonar 64 bit install?
    thx
