I’m not sure if this is a bug, or if I’m just misunderstanding scale per track.
If I set a track to 1/8x scale it only plays the first 2 trigs (the playhead cycles between them).
I was expecting to see the play head go slower across all 16 trigs.
EDIT: I found it was just M.Len, so it works fine. It was just me 
Best regards,
