I have completed a multi-instrument score. I am ready to distribute parts for rehearsal and (yes!) remote recording. I want the two flautists to know what each other is playing so I want to put the two parts on the same extracted pdf. I want to do the same with the 1st and 2nd violins. I guess it should be through either 'manage parts' or' extract parts' but I just can't work it out. Any 'dummy's guide' suggestions?
