.You can set a composition's time signature via its context menu i.e. right-click the composer background -> Edit Properties. You can set it to 2/4, 3/4, 4/4 etc. ...
In the composer background context menu, I see a bunch of options under a "Composition" submenu and a another bunch under a "Editor" submenu. None of them have are related to time signature -- not even in the tempo map -- and none of them contain the word "properties".
Am I in the wrong place? I am using MuLab 7.2.23 in "free" mode. I'll buy it if I can make it do 3/4 time.
Thanks in advance.
