Piano roll and guitar tab for ALL staves at once
I want to use piano roll editor for ALL staves at once, with notes falling into the keyboard at the bottom and keys being depressed highlighted. At the break of two non-staccato non-legato successive notes with same pitch, the corresponding key flashes off for a brief and then flashes on again.
Piano roll type 2:
1. Shortly before a key is depressed, a progress bar appears at the key and starts to filling up, indicate the stave that triggers the note.
2. When the progress bar is full, it starts to drain. The key is depressed and highlighted until the bar is empty.
Similarly, a guitar indicates the position needs to be hit. However, there are numbers like in guitar tablature falling into the strings.
