System Parameters
Controls that set system parameters
affect sounds on all MIDI parts.
If the SC-88 is in Mode 1, Single Module Mode, these settings
affect both MIDI inputs, A and B.
In Mode 2, Double Module Mode, these settings affect only the
parts 1-16 for the Input on which the messages are received.
88-Edit assumes that the SC-88 is in Mode 1, the
settings of some controls will be ignored if the SC-88 is in Mode
2.
