    Question Rewire and CPU

    Hi
    Whenever I load a Rewire GIGA3 instance in Sonar 4, Sonar loads about 20% of my CPU continuously (before I even start playing anything)
    when GS3 uses lots of Gigapulse instance this can be up to 50% of CPU loaded by sonar
    what's going on

    If you have lots of Gpulses loaded, expect lots of CPU drain. I just did a test on my Athlon64 3000+ system. Five GPulses takes 43% of the CPU with nothing else loaded and nothing playing. I don't run Rewire though...

    thanks JF!
    so when we play something, the gigapulse engine alone does not take more resource does it?

    Correct. It just hums along, processing anything that comes its way, including a bunch of zeros. Polyphony is another story. The CPU load varies depending on what it's trying to stream from RAM and the hard drive.

    Gigapulsing is great but wow, what a tax on my system! I can do 16 channels with only 35% and then add 1 instance of Gigapulse imaging for the piano and jump to 75-80% processing! (I'm using an Athlon 3.2 GHz)

    The Tascam reps told me that in the future, dual processing may be optimized for gigapulsing/sampling processes.. but don't quote me on it yet

    Speaking of ReWire, It's something I haven't used a lot but will be now that it's included...

    Just like K-Nar I'm using Sonar 4 Producer - on a separate computer - and so it is possible to rewire tracks via gigabit teleport (LAN connection)?

    I'd also like to ask whether Cubase or other sequencers handle real-time audio editing and vst processing better than Sonar 4.... but maybe that's a question for a different section.

    Thanks,

    Jay
