Editing MIDI Events Just like note events, other types of MIDI events —such as Program Changes, and Controllers—must be contained in a track in order for the track to send the appropriate MIDI message to the device on playback. For example, you might adjust a track’s volume during playback, but the next time you play back that track it may not adhere to that adjustment. In order for the track to always play the same volume, volume Controller events (Controller 7) must be contained in that track. Or, you may experiment with the program (patch) a track plays, but the next time you play back the track, it may not play the program you want to hear—unless a Program Change event is in the track. On playback, when the Counter reaches the location of that event, Metro will send the appropriate Program Change message to your MIDI device and you will hear the correct program. You can record events either directly from your MIDI device or from Metro, or you can insert them manually in the Event Editor, Graphic Editor, or Section Event Editor windows; it all depends on how you like to work and the type of event you’re working with. Here are some of the most common MIDI editing tasks: Inserting Program Events (Changes) into a Track Recording Program Change Events Recording Controller Events Controlling Tempo
