It would appear that the setting of I/O buffer size affects the precision of audio recordings. This is nuts, I don't ever remember this to be the case. Could it just be me?
This is an empty project, no plugins anywhere. Except an external instrument plugin is triggering an external synth with quarter notes to test, and I am recording that to an audio channel.
Note how early and terribly off the recording is at 1024 buffer. It's a little late, but much closer at 128. I thought logic was supposed to compensate for this.
