Core audio again

Question

Um, this problen is happening on brand new arrange as well. Loaded one audio instrument with a logic plug in and the audio is hanging when i play a note key. In other words I press down a key and no sound comes across for about 5 secs then the sound comes on. If I hold down the note it plays for about ten seconds then cuts out again, no sound for intermittent time and then plays again!
Have not changed any settings at all but had a lot of smokers in the room over the weekend while the mac was running. I'm not a smoker myself and cant imagine that this would cause issues with the machine but previous experience has led me to question anything different with the mac environment! really dont know what has suddenly caused this so ......Help?

Answer 1

I don´t understand anything of this....running a single 15 min. track should cause problems like this? On an intel iMac? No way! Even with stock Ram (512) onboard. I could do that 10 years ago on a PM 8200, 100 mhz...OK! only 16 bit/44.1.
And now you suggest disabling widgets and networking and more....What the H...?
Right now I´m doing nothing but writing this, Cpu use: Kernel tasks, 5.5%.
Activity monitor, 2 %, Windowserver(?) 0.3 %, safari 0.10 %, that´s about all.
Then I open a Logic project -only 10 audio tracks and few plug-ins.
Logic: Cpu 20%, Memory 152 mb.
There´s a lot of headroom here, even if I had only 512 mb Ram (I have 2GB).
And the suggestion to have buffer set to 256 or higher is not acceptable/usable or neccessary. Apart from Sculpture, Ultrabeat and direct monitoring
using Space D. I have no problem to go 64... But I set to 128 for safety.
(And sometimes 512 for mixing)
I don´t know why this new macintel behaves like this, but it should in fact be more powerful, than my dp 1.8. If my (fantastic!) pm will not playback a single 15 min. track, I will not consider disabling dashboard. I will dig deeper.
Maybe, just maybe, you could try to open Garageband and change buffer,
low, high, whatever. I´ve experienced conflicts here before.
