Three pages of parameters precede the song fragments.
TIP: to change parameters while your song is playing (for example to dial in mastering settings), hold a 1-16 key corresponding to a parameter while hitting play. Your song will start playing, but instead the UI progressing through the fragments, the UI will remain on the current page (GLob, MStr or FX). You are now free to change parameters at will on that page while you song is playing.
