As I said, it's not a problem specific to the matrix, the notation has it=

Suppose you insert a crotchet over a 4/4 bar. What we need is a way to ge=
t=20
any of the following combinations=20

note rest rest rest
rest note rest rest
rest rest note rest
rest rest rest note

depending on where the mouse click triggering the insertion occurred. Log=

has this, and it's a long standing limitation of our insertion scheme. Th=
e=20
matrix just makes it more necessary to solve, but it's the exact same iss=
ue.

I agree, but I don't understand how normalizing rests will solve the prob=
lem.=20
The rest-splitting code needs to be a bit more clever, that's all.
