How do you get Logic to recognise 12/8 as musicians understand it?!

How do you get Logic to recognise 12/8 as 4 beats of three eighth-notes, rather than 6 beats of 2? If you import a 12/8 loop recorded at 120 bpm, for example, it only plays back at the correct tempo if you set Logic to 80, making a complete nonsense of any MIDI information in the piece. Am I missing something obvious, or does Apple need to address this issue urgently? Thank you...

Logic Pro, Mac OS X (10.6.8)

Hi (and forgive the irritated tone of my last post!). Yes, that's true, but the tempo still comes out wrong. I'm working just now on a song in 12/8 which, if you count 1 and-a 2 and-a 3 and-a 4, as any musician would, clearly runs at around 60 bpm, but you have to set Logic to 90 bpm, creating all kinds of peripheral inconsistencies when working with any external device or application. It's a maddening bug that it may be possible to work around, but we shouldn't have to. I can't believe it would be that hard to fix it - especially as this is a topic that keeps coming up. But thanks to you CCTM for replying.

Unless I am misinterpreting your comments, Logic does display 12/8 as 4 groups of 3:

Hi


Logic considers tempo in 1/4 notes. You need to understand the important difference between 'true' 12/8 vs "12/8 feel":


True 12/8 contains 12x 1/8 notes in a bar.


4/4 time with an underlying "12/8 feel" is 4xquaver (1/8) triplets


If you import a "true" 12/8 loop, but want it to feel like 4/4 with 1/8 triplets, you will indeed need to change the tempo.

This is a serious flaw in the software which should have been fixed many years ago. It gives Logic bad compatibility problems not only with imported loops, but score-writing programmes like Sibelius.

With the greatest respect, your issue here is related to the differences that I pointed to in my first post: a bar of 12/8 is longer than a bar of 4/4, and Tempo is always displayed (in the Transport) as "crochet=".



You want to be able to count it as dotted crochets, and have the tempo displayed as dotted crochets (you can do this in the Score with a 'dotted crochet=' symbol). If you want to 'count' 12/8 as your 1 and a 2 and a etc, you will need to change the tempo.


If, alternatively, you program it as quaver triplets (1/12) in 4/4, your tempo will be as you'd like, and you'll be counting it as you like.


If you want to work in' true 12/8', change the tempo as required, and if you need a 'dotted crochet' metronome click, program one on an Instrument channel.
