Hi,
just a small glitch I have noticed in the weekend: if you rename / move a linked rack file (yes, I know, I should not do it… 
) Cantabile will happily load the song and replace the missing rack with a box without connections…
It took me few minutes to understand why no sound was coming .
So hint: can it at least display a popup saying “Your linked rack xyz cannot be found” ? This would simplify troubleshooting I think 
Thanks!
