I am looking for a solution to replace a live band in a church setting as best as possible. It needs to be able to flow with the service such as, repeat chourus, verse, bridge, etc. as many times as needed. this would need to be controlled by either a simple midi controller or from the laptop. say for instance that you decided that you wanted to repeat the chorus but did not want to have to issue that command at an exact time but rather after the command is issued the program would run up to an appropriate point and then go to the chorus. does that make sense? so that a non musician could simply hit a key or midi controller button and the event would take place at the proer time automatically. would BIAB be appropriate for that ?
