Red Entry Values
When the value being displayed turns red in an entry box, the value is
out of range for the particular setting, and the synthesizer is being
asked to generate a signal that is outside of its specified range. If a
signal is still generated with these red entry values, none of the
specifications or characteristics for this product apply to such a signal.
For complete specifications, refer to “Specifications and
Characteristics” on page 6-1.
