Hello again, Mark,

No, that last was wrong. The RH did not sound only after I moved the notes that belong there up to the RH staff with SHFT+up arrw. The midi played fine until I did that.

It also played fine after using the Track menu, then Split Hands. Composer made a new staff for the RH and put it on channel 1. The RH staff, that was auto channel, could then be deleted.

So, as nice as it is to see once again what a fine job Composer does if you let it do the work, why you have no volume in the piano part, is still a mystery. I am wondering if anyone else is not hearing the piano part at times. If so, I guess the problem, although ironically I hear it all right, is my system. I will borrow time on another computer, and see what it plays like there.

all best,
mgj
