Conventions
The buttons, knobs, and rear panel connectors are referred to in this manual just as
their names appear on the Q20, using all capital letters and in brackets (Examples:
[PROGRAM] button, [< BLOCK] button, [VALUE/ENTER] knob/button, [DIGITAL
IN] connector, etc.).
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 Q20.
