Increasing Performance for live appearances?

Also for anyone interested there... is RAMdisk for windows.

So am I correct in assuming that in order to use RAM disk in OS9, all you have to do is set it in the Memory Control Panel? And the song's samples are then loaded into that automatically? Do you have to set the RAM disk to match the size of the samples?

Any clarification appreciated (I'm a Mac newbie...)

format come back with info on your powerbook and ramdisk performance
inquiring minds want to know.

ps. thats what you get for gaining everyones trust by being so objective.

OK, I'll take that as a compliment as I'm indeed not loyal to any one platform in particular. But I do feel it's necessary for me to stick to certain applications - either because I just love them (Ableton Live) or because I have learned them so well that I know how to complete any task at hand "while asleep" (as is the case with Logic).

And the only thing I got the Powerbook for is Logic, period.

To answer your question - I haven't tried RAM disk yet (can anyone tell me the best settings??) as at the moment I'm busy trying out new functions in Live, getting Reaktor to work on the Powerbook (can be heavy, especially when you try things like disconnecting the Motu 828 during a session and expecting the program not to complain

--- well, I always thought that that was the concept of "hot-pluggable" but nevermind...)

I must say that I'm quite bewildered sometimes when I'm working on a tune I'm only just beginning to arrange in Live, watch it go along at 50 percent CPU and notice that it has got only three tracks playing! It is then that I realise that, even though I do have Gates, Compressors and Delays active in all of them, what I ask of this machine is really not so terribly impossible is it? It just gets fed up with the work I throw at it pretty quickly I suppose.
The difference in Logic 5.5 is astonishing because said tasks don't even register on the CPU meter even when syncing to the internal Quicktime for writing to picture.

I see a clear scheme here: There are companies who commit to Altivec and actually optimise their programs for it (Emagic), there are ones who say they optimise but actually don't (NI), and there are the ones who admit to not having done any optimisations yet but are working on it(Ableton).
The bottom line to this rather long rant is that there's a lot of room for improvment in Live. Usability is top notch, it's only the underlying architecture that needs urgent attention, and I feel Ableton are honest enough to be able to actually trust them on this.

Have a nice day - it's so great not to have to check the forum all the time anymore laptop configuration that might or might not work - Tibook and 828 are the dreem teem.

cheers,

hey man you have a nice day too, I know what you mean about checking the forum all the time for configs, its driving me crazy and I hope to be at your peace of mind level soon.

peace and enjoy

Stubby,

if you've got any more questions, feel free to contact me directly. I know the situation you're in very well indeed....

on my Hammerfall RME card this saves loads of CPU !

Wholly shiznit! This saved me SOOOO much CPU!!! I just turned off the 14 inputs and 8 outputs I wasn't using and vavooom! From 30% to 5% at idle!!! Oh my gaud! Like totally!

Format,

Just in case you're still wondering: RAM disks can be of any size; there's no particular size that is optimal. Just make it big enough to hold the samples you want to put in it and give it a couple of MB of headroom. Just set the RAM disk size in the OS 9 Memory control panel, reboot, copy your samples to the RAM disk, and then select them from within Live. I haven't used an OS 9 RAM disk in a while (I only boot into for DP3), but if I remember right the contents of RAM disks get erased each time you reboot. I think there's an option in the Memory control panel to save the contents on shutdown, but I can't remember if u have to manually restore the contents when you boot up again. 3rd party RAM disk programs like Rambunctious automatically save and restore the contents for you. Hope this helps and I hope I got my rusty facts straight. Just experiment, RAM disks are quite harmless to play around with.
