Possible to change time signature to 4 beats, 3 notes each?

Having trouble with LMMS? Ask about it here.
Hi, is there possibility to change time signature to 4 beats, 3 notes each beat?
I use this for 12/8 african rhythms study, so I needs 12 notes with 4 beats (because of listening those 4 beats with metronome).

Thanks

Just set it to 12/8
Yes, you can definitely change the time signature to 4 bars with 3 notes per bar. This will give you a total of 12 notes per measure. It's a great idea to use this time signature to learn African rhythms in 12/8. Reading https://casinosanalyzer.ca/online-casin ... dollar-cad reviews on different games is also a good lift. By setting the metronome to accentuate four beats, you can develop a solid sense of time and rhythm. Good luck with your study!
