Sorry, I do not understand well what you want.
You want to have 2 songs (with 2 different projects) and be able to jump through them?
exactly
i want to use the spark for live set but without a daw so with the spark 2 standalone program.
so basically, i want to write many songs and then when i play live, i want to switch from song 1 to song 2, then to song 3 etc...
