This is actually a warning - you may loose track of time mucking with it.
It sounds so nice I kept playing with it and almost missed a meeting.

I am no musician but I made up something that I feel proud of just in minutes.

Suggestions:
1. The longer Japanese tutorial really helped but the onboarding should be more descriptive.
2. Let us select/copy the time blocks and paste them elsewhere, so we could repeat the tune to match/emphasize certain repetitive events in the video. (or even bettere, to specify the exact time to repeat the blocks)
