The global page controls the global settings for a track, such as volume, effects sends, synthesis algorithm, and transpose options. The synthesis algorithm specifies how oscillator 1 and 2 are combined.
Furthermore, a 'rais' context menu option raises the master volume perceptually by reducing the master volume ('M.VoL'/'MStr VoL' under the 1/Cd key) of all other tracks by the percentage specified (by turning the value knob while the option is selected). Use this feature if you need to raise the volume of one track beyond 127 (max).
