Whats up with residual sound artifacts?

Probably not the best solution, but a workaround for the bouncing trouble is the following: Extend your song with some empty bars and let logic play these bars until it is completely silent, then make your bounce...

Hmm, this used to be a problem in Logic if I remember rightly with v7.0. Anyone else remember this? It was fixed in an update if I remember correctly, so it seems that 7.2.3 might have broken this. Can anyone confirm?

If we're talking about the same thing, it was never fixed. It's happened to me on all versions of 7.

It happens mostly with Space Designer, as well as a handful of 3rd party instruments, such as Spectrosonics Atmosphere and Trilogy.

There's no "fix" that I'm aware of. My solution is to simply hit play and then stop at the start of the song, in fairly quick succession, 2 or 3 times in a row, to let the buffers empty out, before bouncing anything.

It's not ideal, but it certainly works.

Yes, that's it, it's about emptying the buffers, so we are talking about the same thing. I don't know why I thought it had ben fixed, but I used to have it but don't any more. How strange... Or maybe I've just got used to it. Quite possible!

Very annoying. I find that its easiest to engage the solo button with nothing selected and then hit play to empty the buffer. That way you don't risk filling the buffer again by not hitting stop on time.

Good tip. Since I tend to leave 2 or 3 bars of blank space at the top of my songs, that's not an issue for me personally, but someone who starts their song at bar 1, beat 1 could make use of that, for sure.

I have seen this discussed with the Logic developers on Apple's Core Audio API mailing list.

The issue is due to third party AU's not functioning properly. When starting playback, Logic sends a reset message to the AU plugins (specifically, AudioUnitReset() ), instructing them to clear their buffers. Some plugins do not respond to this message and fail to clear their buffers, so you hear the end of what was last played.

If you have any plugins that do this, please ask the developer to fix them.

If the plugin developers need any more information on this issue, they may contact logic-au@group.apple.com, the address for Audio Unit developers to contact the Logic development team. If they feel it is a bug in Logic, please encourage them to file a bug report with Apple so it may get fixed.

I'm not sure thats true seeing as it's hapened to me when using Logic only plugins...

actually i like the random effect it has. wish i could capture it.
