Thank you, it works!
I have some more questions about piano roll.
If you choose notes on the left, you can see below the notes' label choice "time quantize". There you can see different choices - off, 1/16 note, 1/8 note, etc. What that means? I haven't make any song yet, but I have put the notes to piano roll and chosed different options - off, 1/2 note etc, but that time quantize has no effect to my notes. For what is the time quantize, how it works and do I still need to use it if I want to make a good song?
Above left are hide automation button. Does it mean it shows/unshows automation possibilities? Does I need that automation when my song is ready for mixing or what that automation for?
Next automation button is catch playhead button. Why I need to catch playhead?
