I managed to get the global rackspace forced updated:
-load the audio files in the audio players.
-save and quit the project
-reload the project
Does it work for you?
I’m really satisfied with this solution ! Thanks @schamass for your help.
Could the Reset to #1 button restore the playhead position to the start ?
A last, it could be great to have 3 mores buttons:
-“Stop all” (if something goes not right) (I would map it to my existing “panic” footswitch)
-“Next” and “previous” function to be able to move the “ready to play” target. (In case I miss to trigger one of the sound)
EDIT: Rather than NEXT and PREVIOUS, it would be easier and more convenient to have on button per player.
