Hello,

I'm new to MacMusic so hello all!

I just upgraded to a 24inch imac, 2.66Ghz - 4gb ram. I am running logic 8 with a fireface 400. Everything is great apart from when I have a fair few tracks running (eg 12 audio and 12 software) the response time from clicking and dragging a fader or knob is really slow. I have to wait a few seconds for it to catch up with itself. This seems strange as there is no CPU overloading. I have checked activity monitor whilst logic is playing and there is loads of room, (70% of CPU remaining + over 2Gb of ram spare).

It is also a bit slow when copying and pasting parts of tracks.

I have the Audio driver Buffer set to 256 although changing this makes little or no difference. Also I have Universal Track mode on, Software monitoring on, Large Process Buffer Range.

Also my fireface is up to date.

I am baffled and would really appreciate some help!

Cheers.

Joe

Hello

Are you reading files/recording to your system drive? If so, use another external (firewire) hard drive for this, using the same drive for system/apps/virtual memory and for playback/recording just doesn't make it in OS X.

Cheers for your response.

My firewire is in use with my interface, is there another way round that you know of?

Thanks.

Joe

Either you record/read on a drive in firewire (it should work, it may not) with the interface chained or you use a USB2 drive.

USB2 is not the primary choice, but it'll work good enough hopefully.

Thanks, I will give this a try and let you know what happens.
