I could be wrong, but I think you're only going to find the odd-time signature styles for MIDI only. I don't recall any odd-time RealTracks.

Anyway, the odd-time signature styles basically just takes a bar and slices it into the appropriate time signature from a playback only perspective. BIAB can't show, for example 7/8 time (it will display as 4/4), but if you used a 7/8 style, it sounds fine.

It works because BIAB uses a quarter note resolution of 120 ticks. Across 4 beats that gives you 480 ticks. So each 8th note will get either 68 or 69 ticks (it's not exact, because it's actually 68.5 ticks); however, no one's going to hear the difference between one tick. So the first 8th note will fall on tick 0, the 2nd 8th note falls on tick 68, the 3rd on tick 137, the 4th on tick 205, the 5th on tick 274, the 6th on tick 342, and the 7th on tick 411.

So you can get the sound (again MIDI only, unless you create your own UserTracks and record them exact in 7/8 per BIAB bar), but you won't get the proper notation display, because it's going to show it as 4/4.

MIDI Style Set #38 (called About Time) contains three 7/8 styles:

78_CTRY.STY 7/8 Country/Pop style – About Time
Memo : Country/Pop style in 7/8 (Swing) meter. There are 7 beats (8th notes) per bar. The 8th notes have a Swing
feel. 5 instruments: Acoustic Piano, Acoustic Guitar, Acoustic Bass and Drums. Strings at “b.” Light drum sound
with sticks at “a”. Hand claps and ride cymbal at “b”. Tempo = 130 (based on 4/4)
Examples: Any tune in 7/8 meter

78_POP.STY 7/8 Pop style – About Time
Memo : Each bar has 7 even 8th notes in groups of 2, 2 and 3. 5 instruments: Electric Piano, Nylon Guitar,
Acoustic Bass, Drums and Strings. Tempo = 140 (based on 4/4)
Examples: Any tune in 7/8 met

78_ROCK.STY 7/8 Rock style – About Time
Memo : There are 7 even 8th notes per bar in this style, with a back-beat. 5 instruments: Electric Piano, Clean
Electric Guitar, Bass, Drums and Pad Synth. Tempo = 135.
Examples: Any tune in 7/8 meter

That style set has more than just 7/8, but I just showed those as an example.
