Note spacing

So is there any way to make all the notes of a score have a even space in between them...?

Yes there is. Open this score: Evenly_Spaced.mscz
It should look like this:

You can see that all the notes are evenly spaced. This happens automatically. You don't have to do each note manually.
If this is not what you mean, please attach your file and explain exactly what the issue is.

Can you explain what you mean in more detail? Notes of the same duration should already be evenly spaced. Notes of different durations are supposed to have different spacing; it's a crucial part of how we read rhythm. So you shouldn't be needing to adjust spacing manually under normal circumstances. Unless you are trying to develop a new experimental notation that works differently from standard? if you attach your score and describe what you are trying to do in more detail, we can understand and assist better.
