Garage Band count in function is inaccurate.
I encountered the same issue as someone else who previously identified this problem. I did some testing and came up with the following results. The problem occurs when you try to start the recording in the middle of a bar.
If I start a 1 bar (4 count) count in at 5-1 then there will be 4 clicks and the recording starts at the end of the 4th click, as expected.
1 bar count in starting at 5-2 results in 8 clicks and recording starts at the end of the 5th click.
1 bar count in starting at 5-3 results in 8 clicks and recording starts at the end of the 6th click.
1 bar count in starting at 5-4 results in 8 clicks and recording starts at the end of the 7th click.
2 bar count in starting at 5-2 results in 12 clicks and recording starts at the end of the 9th click
2 bar count in starting at 5-3 results in 12 clicks and recording starts at the end of the 10th click
2 bar count in starting at 5-4 results in 12 clicks and recording starts at the end of the 11th click
I encountered the problem when recording a song which had a mixture of 4/4 and 2/4 bars which resulted in some bars starting in the middle of a bar.
I personally think it's a bug though it could be a particularly unintuitive design. In the meantime I'm just modifying my count in by the above results. Or I can record the new bar on a separate track where I can start at the begining of the bar and then move the resulting recording into the desired track.
