From the manual:
"8.2D Odd Time Signatures
For time signatures based on quarter notes, changing the number of beats in a Pattern can
also change the time signature. Example: Programming a Pattern length seven beats long
will yield a measure of 7/4. Programming a Pattern length 14 beats long will yield two
measures of 7/4. Time signatures such as 2/4, 3/4, 5/4, 9/4, and so on are easy to implement.
For time signatures based on eighth notes, it's easiest to double the tempo so that each beat
lasts an eighth note instead of a quarter note. However, you will have to take this into account
when quantizing and setting the metronome—if the display says a quarter note, read it as an
eighth note.
Plan carefully when mixing odd time signatures within the same piece. If some Patterns use a
time signature based on quarter notes and others on eighth notes, you will need to double
the tempo for the quarter note-based Patterns to match up with the eighth-note based
Patterns".
