Bypassing Notation (and saving a couple of MBs)

[Jerm]

To bypass the notation (and lyrics windows and printing), if you are not going to use it, simply hold the option-key when Metro is starting up.

This has the added benefit of saving approximately 2 MegaBytes of memory under OS X because of the way OS X printing works.

Those megabytes of memory might come in handy, especially if you are using plug-ins (which notoriously leak memory as well).

[Scoot]

does that mean the CPU is taxed less?

or is it more of a case of being loaded, only if the notation is used?

[Jerm]

Well, compared to if the notation window is open and you do a lot of MIDI editing, especially with big MIDI files, it will be much less strain on the cpu.

Otherwise the difference is just memory. When memory gets low OS X starts to choke.

[Scoot]

Doing light things in metro, I can have photoshop golive appleworks mail and safari open quite happily without choking at 768MB.

Maybe my machines too slow to notice.

I do remember going into the mac shop with a friend who was showing me the G5's when they came out and some had 256MB and so many preferences set wrongly that they seemed like a limp dog.

It was not a good way to show off a flagship machine.

For info my metro folder takes 92,68 Mo ram without holding the option key at the opening, and 87,67 Mo when I hold the option key.

Thanks jerm : 5Mo ram saved.

Could you tell me if it's possible to define a midi buffer for metro application, ( or some priority function ) when it works with other applications ??

I use Audio hi jack pro running with recordins at 24 bits/44khz for long recoding sessions ( 3 / 4 hours ) and at sometimes the counter at the transport window is running very slowly while the music sounds good. But one time metro application began to freeze and a this time metro plays always the same note, and impossible to change that without quit.

Do you know a way to rend osX more light and fast ?

I use for instance my new pb 15" 1,5 Ghz with 512 Mo and will have
soon 1,5 Go.

cheers

I do not know. The only thing I can think of is that your hard disk is getting full. OS X is not friendly when disk space starts getting low.

[françois]

is it possible to prior metro manually to other applications ?
the buffer in the preferences is only for audio, or also for midi ?
my hard is now ok I have 25% free ( 15 to 20Go for the systeme part, and 60 Go to data )

Amazing you're having problems with such a powerful powerbook.

The quickest metro would be running only metro.

Quit the finder - you can do this from inside metro.
Click on DIGITAL AUDIO... in SETUP menu
Goto ADVANCED button and click on little blue car = quits finder

No record tracks ON if not recording

SWITCHES - playback scrolling - OFF

Midi and audio thru OFF if not needed.

SETUP - Chasing... may slow things???.......



The worst thing is using the same drive for everything.
Your best bet is to use a firewire drive and put the audio on it.
BUT from memory you use a firewire audio interface as well.

Does your model PB have 2 firewire ports?

Now it's fine, but on stage I had some troubles....

I have a partion for the system and another for the data

Does your model PB have 2 firewire ports?

one 400 port, and one 800 port

[Scoot]

Then you have the ability to get a FW 800 HD and run the audio interface on the 400.
