Problem with live loops, sequencer and odd time signatures

There is no way to sequence simple odd time signatures like 7/4. If i set the loop lenght to 7 beats the sequencer starts a new cycle in itself and crashes the beat. If i reduve the loop lenght to half of 7 ( 3.2 beats) the loop becomes slightly too long and looses the rhythm.

I am trying to do electronic dance music in odd time signatures and it seems to be impossible with the sequencer and live loops.

I am asking apple, for the sake of evolving music, please make options for odd times in sequencer and fix the glitches in live loops!
