Hi all,
So I was able to noodle with Logic a bit this evening, and I think I understand what is happening here. When I record, I most often use a 1-bar count-in. When I press record, the playhead jumps to the start of the previous bar regardless of where I am in the bar I currently am in; for example, if I have the play head on beat 2 of bar 2, then press record, the playhead will jump to beat 1 of bar 1. The same will happen regardless of where I have the playhead in Bar 2 before pressing record.
So, I had made the assumption that when pressing record with a 1-bar count-in, then the resulting audio file (and corresponding region) would include all the time from the start of the count-in onwards. Logic does in fact record all the audio from the start of the count in onward, but the region that ends up displaying in the arrange window only starts from where the playhead was originally placed BEFORE pressing record. I have some screenshots to illustrate this.
Here I start with the playhead at Bar 2, Beat 3.5
Then, I press record and capture a synth note from a soft synth. Here we can see that the resulting region has been automatically trimmed to where the playhead was originally set, even though there is audio recorded before this point (the MIDI note was triggered before the start of the displayed audio region). We can see in the list of audio files on the right that the region can be expanded to the left to uncover the recorded audio.
Maybe this is expected behaviour for those that know more about Logic than I, but it was not what I was expecting to happen when recording. Up to this point I had been relatively lazy in where I placed the playhead prior to pressing record with the 1-bar count-in, which made it seem that the recording was trimming to a point in the waveform but really it was only starting the region where I originally had the play head (and I had to expand the region outward afterward).
