Different meters on different staves

[Tim Mariott]

I have come across something peculiar in a choral score that I am entering. For just a few bars, one vocal part and the piano accompaniment are singing/playing in 6/8 meter, whilst three other vocal parts are singing in 2/4 meter. I wondered why we had so much trouble when we tried to sing this piece last year and we are trying again this year!

As far as I can see, Notation (quite sensibly in my view) sets the meter across all staves and I cannot see any way of setting the meter for an individual stave.

Can you just confirm my understanding and I will find a workaround that is sufficient for practice purposes.

Many thanks
Tim
