The document details the operation of scene memories on the Yamaha PM3500 console. It describes three distinct memory modes: NORMAL for standard operation, CHECK for previewing parameters without affecting the current setup, and UTILITY for managing MIDI transmission settings like Program Change and Control Change messages.
Users can recall scenes using DIRECT RECALL keys, UP/DOWN navigation, or number keys. The guide also covers storing new scenes and controlling individual channels through external MIDI controllers connected to the console's MIDI IN/OUT terminals.
MIDI Program Changes 0 through 127 correspond to scenes 1 through 128 on the console.
Enter CHECK mode by pressing the CHECK key; this allows changing parameters and viewing bus status without affecting the current setup until confirmed.
