try RB and see if it meets your needs.
in RB one isnt limited to a few time sig numerator/denominotors.
in addition in rb one can see in tracks view the divisions in the bar for example.
there is a dialog in rb specifically to set odd time sigs.

I tried RB, and while it is a nice app, I miss some of the global editing features in my sequencer of choice, Master Tracks Pro.
These features save me hours of time when working in MIDI.
Example: if I have a drum track with all the percussion instruments in it, and I decide I want the snare hits only on beats 2 and 4 to be louder, I can highlight the drum track, go to the change filter and make only the snare drum and only on those beats louder by the measure I want.
Example: If I decide I'd like to shift the 3rd beat of any triplet to be a little bit later (increase swing factor), I can highlight the whole sequence and move only the 3rd beat of every triplet a little bit later.
There are more advanced global edits than that, but I'd have to show the dialog boxes to get them across, plus a lot of words making this a long, off-topic post.
Global edits like this save a lot of time, I'd hate to do it on a note by note basis.
If I need notation, it's usually just a head chart, and I can do one up in a couple of hours or much less, depending on the complexity, using Encore or MuseScore.
