You could use the built in audio player but that player was really designed to play backing tracks or short loops and you’ll have to explicitly map notes to the play/stop parameters of different tracks.
Much easier to use a free sample player designed for the purpose.
I should probably rephrase. I literally just need to play an intro mp3 at the beginning of the show it’s about 1:16. Would the audio player be appropriate for this? Not changing the file at all. I could use iTunes but just trying to simplify.
Sure you can use it for this.
Insert two instances of the Audio File Player in your wiring view and connect them with an audio output or mixer block. Then use two button widgets, one for each player, and connect them with the according play/pause parameter of the players.
One button should be set to have an initial value of 100 (=ON), also for rackspace activation, the other should be MIDI-learned to the incoming note-ON from the corresponding MIDI-In and channel.
So the first button will be swtched to ON (=PLAY) with every activation of the rackspace, while the other should be reacting on a note-ON (as you set it).
(Make sure you have loaded the respecting audio files into the players and have “loop mode” switched OFF).
That should be it.
