986 Chapter 39 Project Settings and Preferences
 Stereo Mode: You can choose between Joint Stereo or Normal Stereo in this pop-up
menu. Depending on the original file, these settings may (or may not) offer any
audible difference. Experiment with both settings to determine your preference.
Reset Preferences
Activate the appropriate checkboxes for “Control 64 off (Sustain)”, “Control 1
(Modulation) to zero”, and “Pitch Bend to center position” to send reset messages of the
specified type to all active instrument channels.
This can be useful if you are encountering hung notes, or are finding that controller
settings are incorrect when in Cycle mode (or when returning to the beginning of a
section or the project start point).
