| Summary | 0009457: MIDI List Editor unexpected behaviour, can cause crash. |
|---|
| Description | When I started to learn Ardour, I simply used it as a "tape recorder" and effects processor for my guitar.
"Convalescence - Part 3" became the first track I made this way, and also my very first FOSS production.
Now I'm craving music production of a more structured nature, so I've started to learn MIDI editing with Ardour.
While exploring the functionality of Ardour, I discovered the MIDI List Editor.
So, I tried changing some note values and I discovered that the List Editor is not behaving right. |
|---|
| Steps To Reproduce | 1. Create a MIDI track (instrument optional)
2. Create a MIDI-region, about 8 bars long (you decide).
3. Draw a half note (1/2) at or near the beginning of the region.
5. Hit "G" (grab mode).
6. Right-click the region, go to MIDI - List Editor.
7. Left-click the text describing how long the note is.
8. Left-click a different note length from the list.
9. Try changing note values with the mouse wheel.
Expected behaviour, when changing note length (left-click in list):
All available note length in the list should affect the note length when clicked.
Actual behaviour, when changing note length (left-click in list):
Only "Half", "Quarter", and "Whole" affects the note length.
Expected behaviour, when changing note length (mouse wheel):
Mouse wheel should switch between note lengths in the list:
Actual behaviour, when changing length (mouse wheel):
Mouse wheel up, switching beyond a "Whole" note length gives numerical values.
Mouse wheel down, swithing to a note length shorter than "Quarter" gives a note length of "1" tick.
Expected behaviour, when changing note start (mouse wheel):
Mouse wheeling up/down over the note start value should move the note forwards and backwards in time.
Actual behaviour, when changing note start (mouse wheel):
Mouse wheeling up/down always moves the note forwards in time, regardless of scroll direction. |

| Additional Information | This behaviour is seen in rev 7.5-636-g0633254820, pulled from git a few hours ago.
There is no visual feedback on which column is selected when navigating with the Left/Right arrow keys. I tried a different color theme, but that turned out is not the issue.
Changing the note start values via keyboard entry does not have any effect.
Ardour can crash with an "Address boundary error" (as reported by fish, in my case [https://fishshell.com/]) when attempting to change values with the keyboard. If I discover a procedure to reproduce, I will add a comment to describe it.
The manual does not state anything about using the mouse wheel or changing note lengths from a drop down list.
