Stem.note-collision-threshold

[Robert Mengual]

Hello everyone,

I am developing a custom music notation in which distance between notes is different from the standard one. Instead of the tipical distance from C to D of 1, in mine for example this distance is 2/3.

This of course causes notes in the same chord that are 1 tone away to overlap. I wanted to fix this by overriding Stem.note-collision-threshold to 1.5 (which would solve it). However, it won't allow to pass float numbers. My question is, shouldn't it allow them? Why not?

In any case, does anyone know how might I approach this challenge in a different way? I tried setting a different StaffSpacing but I was unsuccessful as well.

Thanks in advance,

Robert
