I'm using the `\offsetPosition` command (https://lsr.di.unimi.it/LSR/Item?id=748). Unfortunately, it fails in a multi-staff, real-world piece: it has zero effect, and I don't know why. What could be the cause for that? If I had a hint, creating an MWE would perhaps be more straightforward...
Interestingly, using the 'deprecated' part of this snippet instead I get warnings like cyclic dependency: calculation-in-progress encountered for Slur.positions but it actually works... Werner
