Hi
I've noticed this problem: I have a Powerbook g4 15" OSX 10.4.4, a Lacie Firewire external disc, a Terratec Phase 24 firewire soundcard, an M-Audio Midisport 4x4 midi interface, a Clavia Nord Lead, a Waldorf Xtk, Yamaha Fs1r, Oberheim Matrix 1000 and an Yamaha 01V digital mixer. The digital out of the mixer is connected to the digital in of the soundcard. In Logic Pro 7.1, when I record the stereo out of the mixer thru the digital cable (spdif) into the soundcard I get cracks and pops. I'm always recording to the external disc (7200rpm). I've tried the Powerbook's hard disk and I get the same problem. Usually the recorded file sounds good at the beginning, but after some minutes it starts to have those cracks and glitches. And I'm sure they're recorded. It´s not a playback problem. I'm recording at 24bit 44100hz. I've tried recording second time and it had no cracks and pops ! Does Logic need to play all the song before it is recorded ? Do I have something wrong on my preferences ? Is this a bug ? I've also noticed that when I use Kontakt 2 and I play a song for the first time, as soon as the song pointer reaches the Kontakt notes Logic stops with the following message: " CoreAudio System Overload.The audio engine was not able to process all required data in time.(-10011)". When I play the song the second time, Kontakt plays with no problems and the song doesn't stop. Is this related to the cracks and glitches problem in some way ? What do you think ? Thank you. Alex |

QUOTE (Metro SE @ Feb 18 2006, 15:32) The cracks and pops definitely sounds like a master word clock sync problem. Are you sure that your digital audio card is in 'external' sync mode? Try swithcing it so that the card is in internal sync and the O1/V is in external sync. The Kontakt problem is most likely unrelated. If it plays back fine the second time this is most likely because the samples are not fully loaded into memory until the second time and the first time is causing VM (virtual memory) page faults. How much memory do you have in the powerbook? the Yamaha is set to internal and the sound card to external. I'm sure about that. if I switch it the Yamaha no longer sends thru the digital output and the soundcard doesn't receive any signal. well...in fact I didn't connect the digital stereo out from the soundcard into the Yamaha mixer...do you think I must have the 2 cables connected? regarding the Kontak, what do you mean by "memory" ? I have 1,5gb ram and this happens even if the Kontakt is loaded with only one simple and short sample... anyway, thank you for your help. |
