You don't have to give me ALL credit. You obviously put some work into this!
Also, I don't always chop them to where they're perfectly in time when the get uploaded.
What you can do is turn off the grid snapping ( the hashtag looking symbol at the top left of the timeline) and drag around the loop until it fits with the drums or click track.
What I like to do is double click on the loop and edit the audio inside!
All of that aside, thank you for making this and exploring some rock!
