How do I get a tighter grid for MIDI editing in GarageBand 10?
In the previous versions of garageband, when I double-clicked on a region and the editing window on the bottom popped up, I could use the ruler button to choose how tight the quantize grid was.
In a 2016 update I don’t find this control in the same place.
How can I change that timing grid now?
You can! But the feature is different than before. To get a smaller grid you can click the arrow at the right side beat/tempo/key led area and select "time".
You can't. Apparently GarageBand is either hiding the option or it no longer exists.
