I am a musician, not a rocket scientist! In one of my imported MIDI files, I've been trying to set the panning field using the circles in the mixer and the mouse. In this particular file, the setting won't stay, at least in the wind samples. OK, having tried to read the online instructions, I have to say they are stereo instruments so presumably converting them to mono would be the way to go except that the circle completely disappears in that case. The third option is "surround" which seems to work but I don't know what it is all about with its various "pucks" (no I won't go there!) and I'm afraid to leave it that way, at least without further knowledge. Any help would be appreciated.
