hi Bassman 24,
The purpose is to have several reverbe on the singing(song) which we can change with the footswitch and change only that that and not the other regulations
Thank you for your answer
Small concrete case: I prepared at home reverbes A and B and to protect it scéne A and B thus with all the regulations of tracks
During the show we increase the volume of the track of the singer we are on the scene(stage) A which lasts several pieces when I am going to be thought of in the scene(stage) B as another song the level of the track of the singer be going to return to the regulations of the scene(stage) B that I prepared at my home!!!! Thus it will be necessary to make a correction of the volume, it would be necessary to have the possibility of protecting in scenes just those whom we want to change.....
