Should Cursor When a Tie-in or Continuation Note, that wraps Into Next Row, Like a Chord Drop to the End Note Head or Glide? #2736
-
|
When a tied/sustained chord crosses a system break, alphaTab’s playback cursor appears to transition from the beat bounds at the end of one system to the next beat bounds on the following system, rather than visually tracing the sustained tie/continuation across the row boundary. Is this the expected default behavior of the built-in animated beat cursor? If we want a cursor that visually continues through tied/sustained notes across system breaks, is the recommended approach to implement a customCursorHandler using boundsLookup / playedBeatChanged, rather than expecting the built-in cursor to interpolate through the tie path? Here are some images to show what I mean: 
Or should it continue gliding through on the new row more like this: |

Yes this is the expected alphaTab behavior. There is no built in mechanism to do a half/half split of the duration to animate to the system end, and then continue from system start to beat. You can implement such an animation sequence on your own via a custom ICursorHandler (and likely IScrollHandler to scroll at the right time) |

Does alphaTab expose onBeatCursorUpdating independently enough to observe
cursorMode without handing primary cursor rendering back to
ICursorHandler/native cursor behavior?
