Conventions

The buttons, knobs, and rear panel connectors are referred to in this manual just as
their names appear on the QuadraSynth, using all capital letters and in brackets
(Example: [PROGRAM] button, MIDI [¬] and [®] buttons, Quad Knob [1], etc.).
When text from the QuadraSynthÕs display is quoted, it is indicated by a set of
quotation marks (Example: ÒEDITING: SOUND 4Ó) .
When something important appears in the manual, an icon (like the one on the left) will
appear in the left margin. This symbol indicates that this information is vital when operating
the QuadraSynth.
