In Ensemble Stars!! Basic, Appeal Talks are randomized conversation events the player receives when playing any kind of produce course, such as event or D.L.F.S. courses. Each character has 3 Appeal Talks total. To potentially trigger an appeal talk of a particular character during a course, you must click on a room that contains the character in it. Appeal talks cannot currently be triggered in Ensemble Stars!! Music.
Minitalks are the conversation events a player receives when playing any kind of produce course that contains a companion character, such as event or D.L.F.S. courses. Each companion character has 6 minitalks total; 3 normal, and 3 special. To trigger any minitalk, you must complete the criteria stated in the upper left corner of the course screen, located next to the turn counter. In Ensemble Stars!! Music, it's possible to trigger event minitalks automatically after playing an event song, but non-event minitalks are currently unavailable.
