The Player recognizes all the time signatures provided in the editor. However some styles will not play some time signatures (an error message will show when attempting to play the song). For example Pop-Shuffle does not play in 3/8; Blues-Lucille does not play in 5/8.

This is how they are interpreted:
4/4, 3/4 and 2/4 simply play as written in all styles

2/2 plays as 4/4;
3/2 plays as 3/4 + 3/4;
5/4* plays as 3/4 + 2/4; (see reverse options below)
6/4 plays as 3/4 + 3/4;
7/4* plays as 4/4 + 3/4; (see reverse options below)

3/8 play as written (available with most styles);
5/8* play as written (available with most styles); (see reverse options below)
6/8 plays as 2/4 so a triplet based style like Afro 12/8 is recommended for this time signature;
7/8* plays as 2/4 + 3/8 and does not work with triplet based styles like Swing or Afro 12/8; (see reverse options below)
9/8 plays as 3/4 so a triplet based style like Afro 12/8 is recommended for this time signature;
12/8 plays as 4/4 so a triplet based style like Afro 12/8 is recommended for this time signature. 12/8 is considered as 6/4 when generating even 8th (non-triplet) styles.
 
* Reverse options for 5/8, 7/8, 5/4, 7/4 (v2024.4 or higher)
Use text to specify internal division feels for a measure (2+3 or 3+4 etc.)
 
 
Compound Time signatures
You can use more than one Time signature within a song, to create sophisticated compound time signatures.
Here’s an example of 9/4:
 
 
And the various  x/8 time signatures can work with each other for songs having 8th feels.
You can use compound signatures or text (2024.4 or higher) for specifying the feel/pulse of odd time signatures within a measure, here is how.
 
Note: 4/4 is the default time signature if none is chosen at the beginning of a song. Always make sure there is a Left barline (recommended is the Left double barline) at the first space, first measure appearing just after the time signature so the player interprets the beginning of the song correctly.
