I am having a problem with Logic7 "stuttering" the audio when I start or stop playback quickly. One easy way to reproduce this problem is to start playing at a certain measure, and hit play again while it is going, so it starts again from the same spot. It will stutter for a split second before playback starts. This happens on all sessions that I have tried, with all audio hardware settings I have tried. Is anyone else able to reproduce this bug? Anyone know how to make it stop? Thanks.

Are you guys using Wave plugs?

Ours is definitely stuttering, only on start or stop, similar to Sumit Das. We do have Waves Gold and lots of other third party plugs. Have not had time to properly troubleshoot the issue, but I know it does happen to every track, and does not seem to be song-dependent (every one I've tried does it.) It does not depend on buffers or any other hardware setting. It does seem to be in sync with the tempo, strangely enough. Let me know if you have any other ideas.

The audio has to travel back & forth to the card and it has to be buffered. This buffering is probably the "stuttering"... Louis

This buffering is probably the "stuttering"... Possibly, but this bug only showed up with L7, never ever with L6.x.x . I suspect it is due to some optimization in the audio engine. It scared me at first because I thought things would lock up, but I'm used to it now. L7 is rock solid for me. -smeet

I was also having a problem with stuttering. The surefire way for me to see the problem in action was to have Logic 7 open in the background not playing, then open itunes and play a song, hit stop and it stutters, until you either close itunes or click back onto Logic 7. This also happened to me when I previewed audio clips through the finder. Here is my setup... Logic 7 Dual 1 gig, 10.3.6 M-Audio Audiophile 2496 Phatmatik Pro, RM IV, CA5000, FabFilter One, Oddity Hydra and SuperCamelPhat -Wrapped No Waves plugs anymore ;) It happened when the OSX Sound Output was set to "Analog 1/2 Delta Audiophile 2496" (which are the outs on the card) and Logic 7 was also set to that as a driver.I had to switch the OSX Sound Output to "Multichannel Delta Audiophile 2496" and kept Logic set to the Analog 1/2 outs and that fixed the issue. Since you have an M-audio interface, this might be your problem. Mike

Hey! I just ran into this problem, after upgrading a G4 AGP 400MHz to OSX 10.4.6 and Logic Express 7.2, with a Delta 66 card (built-in audio doesn't exhibit the problem). I tried several of the solutions floating around - but the one that's working consistently for me is really simple: arm a track for recording and then un-arm it. So far that takes care of it, every time (it seems to be required after the app is started or any re-launch for a core audio change). According to the post where I saw that - http://community.sonikmatter.com/forums/lofiversion/index.php/t22659.html - there's supposedly an odd bug that can cause that problem with some drivers. At any rate, it's working for me....

I also have the problem but with Logic 6.x - I also have a Delta-66. My solution is simpler than yours. Double click on the Transport bar, where there BPM is displayed: Just underneath the BPM is the memory consumption of the current open file. Double clicking on the memory value brings up the "Reorgansise Memory" popup and Clicking "OK" will recover some memory and also cut the stutter out stone dead. rachel -- Rachel Polanskis Kingswood, Greater Western Sydney, Australia grove@zeta.org.au http://www.zeta.org.au/~grove/grove.html "They who would give up an essential liberty for temporary security, deserve neither liberty or security" - Benjamin Franklin, 1759
