  • pro tools/powerbook help!

    Recording up to 8 tracks at once (I haven't tried more) with my powerbook running protools seems to be no problem, though I need to do it with a hardware buffer size of 1024 and a CPU usage limit of 99%.

    I feel sure this hardware should get results with a smaller buffer...

    It's a new (as of dec '05) powerbook (1.67ghz), pro tools LE 6.9.2, 1GB of RAM (the new stuff), a seagate 7200RPM external HDD drive I've borrowed, which doesn't seem to make it much better than recording to the system disk.

    My real problem, though, is that I can't even put a 4 band EQ on every track, let alone any reverbs or compression, etc. Shouldn't I be able to do that?

    When I do, the computer pretty much always locks up and says:

    "The operating system held off interrupts for too long. If this occurs frequently, try increasing the H/W Buffer Size in the playback engine panel.

    Which, of course, I have done to the maximum I can.

    Does anyone know what I should do?

    Also, is there a checklist of things to do to your mac to make it run as well as it can.

    I felt sure when I bought this gear that I should have no real problems with cpu/HHD/memory issues. Was I wrong?

        heh... thanks.

        btw, do you mean:

        wrong as in

        "wrong to hope I wouldn't have problems"

        "something's wrong if you're having performance issues of this kind"?

          I would expect a lot more performance from your Mac, than you are getting. I can run more than that on my G4/400 and it's much slower than your laptop..

            Check in with Digi support, could be the power harness issue the 002 is famous for.

              Have you checked your Energy Saver preferences and set the Processor Speed to "highest"? It might currently be on a lower setting.

              You can run Activity Monitor to get an idea of what applications are using system RAM.

                Thanks a lot, guys.

                I'd pretty much done all that stuff above, apart from call Digi!

                FYI, the new (after Oct 2005) powerbooks are not yet all tested and stuff.

                The bottom line is that installing version 7 seems to sort out my problems, and they aim to have the new powerbooks totally compatible by the end of January... or at least report why not.

                And I'm typing this while a tune plays out of pro tools in the background, whic is unprecedented!

                I guess the answer is always just to plug away till you find the solution!

                Cheers.

                  Cool. I hate when people think their powerbooks are too slow to do audio with..

                  Merry Christmas..!

                    Are your HD's formatted with Journaling on? In 6.9 it needs to be on. Also turn your record Allotment to a more reasonable time.

                    There is something wrong with your config....

                    So PT7 helped? Well, that makes sense because there was a disc Access problem w/ 6.9. Also, What version of Tiger? If 10.4.3 then there has been some reports of issues....

                    Go to the Digidesign User conference, and you'll get TONS of Help with this.

                      Thanks

                      Actually, since I put LE7 on, I've not had a single problem, and I can do mad stuff like watch telly on an eyeTV and write a DVD at the same time as doing audio playback stuff with plugins.

                      Not that I should be doing that, of course, but it's always amusing to push the system.

                      It's not "hit the wall" (is that the expression?) once.
