Hi Mark,

"the piano part sometimes was inaudible"

I think I know what you are referring to, now. The 1st movement of the first concerto is the one I had listened to in Composer, but I guess I hadn't the first of the second. I imported the midi a while ago and the piano RH had no volume, as far as I listened. I finally figured it out when I looked in Track Setup, where the channel for the RH was listed as auto, while the LH was listed as channel 1.

The solution was to make the RH channel 1, also.

No idea why Composer might have made that auto, but wonder if it has anything to do with the fact that the left hand plays alone for a number of measures before the right joins in????

Anyhow, it sounds a LOT different with both hands on channel 1 :}

best,
