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. -------------------- Our Classifeds • Nos petites annonces • Terms Of Service / Conditions d'Utilisation • Forum Rules / Règles des Forums • MacMusic.Org & SETI@Home

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. -------------------- Our Classifeds • Nos petites annonces • Terms Of Service / Conditions d'Utilisation • Forum Rules / Règles des Forums • MacMusic.Org & SETI@Home
