    Ok. Have you tested the VI on a PowerMac G5 Quad? How does it perform, can you fill up the 8GB ram?

    I'm considering getting one of these since I have cubase SX3 (which I know from PC, and is Mac compatible), and then since the new VI also is mac compatible I'm wondering if it will be a good buy?

    I'm not really sure I can afford it, unless I get a great (and I mean great) benefit from switching.

    Might I aswell wait for a PC equivelent? Any guesses how far is this away?

    Please shed some light

    I volunteer to test the VI with my Quad G5!!!! If no one else has done it.

    Hi -can you tell me a bit about it? How much does it rock?

    I asked a similar question a few weeks ago. VSL didn't respond directly. but one user noted that Logic commands its 4GB (approximately) of RAM, and the plug-ins (even VI, in this case) are necessarily limited to it. Again, no confirmations from Vienna on that.

    It would be an extraordinary benefit if we could sidestep the 4GB limit via plug-ins. Could plug-ins outside of Logic on the same computer -- perhaps ReWired back in through Environment -- possibly help us? I speak in hope, not expertise.

    Hows the ram limit of Cubase on Mac? Do any of you know what Logic haveplanned in regards to the 4gb limit?

    Well, I guess - as Cubase is cross-plattform and a GUI (traditional) app that it has a 4 GB RAM limit.

    64 bit coding (which is necessary for more then 8GB) is not supported for GUI apps. it must have a client server architecture, then the processing can run in 64bit and the GUI in 32 bit.
    For SX3 this is not the case.
    It would be interesting to test it with externally running VIs - but Cubase does not remember the virtual software ports - perhaps because its PC developers do not know such stuff - drove me mad with the Perf Tool and Cubase always forgetting the outputs and inputs linked to it. And yes, if you have interapplication MIDI enabled in OSX Cubase likes to build MIDI-loops and crashes - the same dilemma with that PC-app running on Mac.

    Maybe one should check out with a more intelligent app like Digital Performer to run the VIs as external instruments. At the moment there is not much standard possibility to route the VI into the DP mixer though. You would need something like Jack or the cycling flower.... or route it externally.

    Just a few thoughts.

    I have the Quad with 4.5GB of RAM in it; it runs circles around my dual 1ghz G4 - many many tracks don't even make a blip in the System Performance window.

    One thing I have noticed, tho -- and it may not apply in this situation, but what the heck -- I thought that Logic could access 4GB of RAM, but when loading, say, 2GB worth of NI instruments (symphonic choirs, an SATB multi setup) I quickly run into a ceiling an an error message that says "you're running out of memory." On another forum, someone mentioned that you can still load only 2GB worth of instruments.

    That said, I'm guessing that the next Logic update will be able to access more of the Quad -- seems like Apple always follows up a new machine with software that can best take advantage of the new architecture.

    Well, I think with 4.5 GB available RAM Logic will not be able to access its 4GB (aka 3.7 GB) RAM.

    Have you checked Activity Monitor or Top (in the Shell) for free RAM?

    And when mentioning NI instruments, you refer to K2 or other stuff (K1.5 and players that are based on that legcy code) - the reason I ask - K2 is pretty intelligent managing open files, the older are not AFAIK.
    How many open files does Logic have (you can see that with Top)?
