In this particular file the main volume increases already at the first tick/beat of the score.

This file uses three controllers: volume, pan and expression. Changing the volume controller value only changes the channel volume level, not the main one. Erasing the expression line or changing the pan value doesn't effect the volume level. So it seems to me that I can't solve this problem with Composer.

Thanks anyway for your help.
