How to create midi loops
I haven't managed to find any help items on this, and what I've seen on the internet is out of date. I am imagining that I should be able to get a midi grid on screen in which I can enter in individual beats in the place where I want them, and also play them and then edit so they are snapped into exactly the right place. One reason why I am imagining this is that I've just watched a video showing it in a previous edition of Garageband!
Have I missed something, is it actually possible to find loops in different time signatures? I've tried changing the time signature indicator at the top but it doesn't work.
The drumming I want is quite subtle and minimal, to go with music that often has a hint of Caribbean or African lilting rhythms, so even if the time signature is four four, I want a dotted skippy sort of rhythm.
Your helpful comments most welcome!
