I'm writing a piece in swing feel. When I use the grace note, Sibelius plays it differently than how I think it should sound but when I notate the same thing using a dotted 32nd, it plays the same thing correctly. I'm sorry if I failed to phrase this question appropriately :( I'm attaching an image to show you what I mean -
Below is an image of how I ended up notating it. Is this a playback issue or is my assumption of using an acciaccatura wrong here? Thank you so much!
