Hi and thanks for reading what may be a simple question. I am new to M2, having used the first version a couple of years ago for a keyboard job on the road. This time around I have been charged with the job of migrating over backing tracks for live performance from a minidisc player to mainstage 2 as we are about to go overseas and the minidisc player is huge. i have an m-audio for multi track output. I need the drummer to run the show from his kit using a macbook pro and m2. we have four audio tracks to run simultaneously per song (left, right, bass and click) and we have about 20 songs. I have imported all the audio into logic and exported each of the songs' four audio tracks into folders as wavs. I have opened mainstage 2 and selected the eight track template. It is set up perfectly for what i would want, if I only had one song to play. However, as soon as I try to add another song, or another set, to set up the tracks for the second song of our show, the template LOSES ALL MAPPINGS! And I cannot work out how to add the wavs for the second song and so on. I have read the manual. I have googled. I have youtubed, I am going MAD. I cannot for the life of me work out how to do it. All I need to do is have set up a concert (actual terminology not mainstage terminology) of about 20 songs, each with 4 simultaneous backing tracks as they need to go out to separate outs to the FOH desk. I have also looked at running the concert as 4 long wavs and using markers, but that is cumbersome for rehearsal purposes if the user has to start and stop and scroll through. What am I missing? Please help. I have to finish this urgently. thanks in advance... Paddy.
