I am trying to use beatbox 2 to make a drumbeat in 3/4 time but the grid only shows multiples of two. How do I make 3/4 drumbeats? Will beatbox work, or should I use a different synth?
I'm assuming you are asking about MMM? You didn't say.
I have found NO way to play ANY synthesizer in 3/4 time in MMM (-15). Even if you set the arrangement time signature to 3/4 time it will change back to 4/4 time as soon as you add any soundpool object or open any synthesizer.
Even if you change the time to 3/4 after the fact, only the grid and length of the object on that grid changes. ALL of the soundpool objects and synthesizers are designed to play in 4/4 time. Although the metronome does change to a 3/4 beat.
I imagine the only way to get a beat in 3/4 time in MMM is to record your own beats from an external sound source.
