    I was using WDM drivers at first with the VSL VI. Seemed to work fine with just one instance. But with 3 or more instances I started getting lots of pops and audio glitches and cpu spikes. I switched to ASIO drivers and magically the pops and spikes disappeared. Just thought you should know.

    Nope. I'm now getting lots of drop-outs with 5 instances using ASIO drivers. Seems like I should be getting much better performance than this. Any ideas?

    Switched to different ASIO drivers. Now running smoothly with 5 instances. Seems very sensitive to drivers.

    GUYs,

    us MAC users are having the same issues

    please see my thread

    "VI Mac AU Plug......Is the memory Leaking?"

    So we can all assist in trouble-shooting this...

    Hi Jay
    Your soundcard should have a special ASIO-driver with its own software "frame". There you can set different things like the number of speakers etc. One parameter is "samples/buffer" or something like that. It is possible to set different values: 128, 256, 512, 1024, 2048...
    The lower the value the lower the latency - the higher the CPU's stress.
    So it is a conflict to keep on one hand the samples/buffer low and on the other hand the CPU stress low too. I guess the samples/buffer is around 256 at the moment. Increase it to 512 or 1024. The latency is ca. 23 ms with 1024 samples/buffer. It is only just OK to work with this configuration (1024). Try it out.
    BTW Which soundcard do you have?

    I wish you success!

    It is important that you choose the soundcard's own ASIO-driver.

    [8o|] No Multimedia ASIO driver (MM-ASIO)
    [8o|] No ASIO-DirectX driver

    Yes! What you say is very true!!

    Thanks,

    Computer crashed. ASIO drivers stopped working. ??? Retried WDM drivers. Now works fine with 8 instances + WDM drivers with very low latency. ??? Drivers may not be the problem.
