I didn’t look at the project, but swing works globally on Tracker, so the track starts the swing when the first swing FX is triggered, if this isn’t at the first bar then you wouldn’t have swing until then. Not sure if this is what is happening, but might be.
So I’ve just entered the swing FX value on the first note of the bar instead of the specific notes 8 & 10 and it works properly the way you explained it. I was approaching it the wrong way. Thanks for the clarity on global swing.
The way I first did it, I should have used micro-move, if I just wanted to affect the timing of only those two notes without affecting the timing of the whole song.
