Yamaha RX21 - Manual (Page 25)

First, press the CLEAR button from the pattern select mode (in this case, the pattern
number selected is of no importance). When the “CLEAR PTN pp ?” display appears,
simultaneously press the CLEAR and PATTERN PLAY buttons. The LCD will switch
to “CLEAR ALL PTNS ?”. If you decide you don’t want to clear all patterns, press
the -1/NO button to cancel the clear function.
If you want to clear all patterns, press the +1/YES key. The LCD will show the
“ARE YOU SURE ?” display, to give you a second chance to confirm your intention
to clear all patterns. Again, If you decide you don’t want to clear all patterns, press
the -1/NO button to cancel the clear function.
If you are sure you want to clear all patterns, press the +1/YES key. The LCD will
show the “ALL PTNS CLEAR” display, followed by the “SELECT PTN pp” display.
The “clear all patterns” function initializes (zeros) the pattern memory, and can
be used to restore normal operation should an operation error cause the RX21
software to malfunction. It’s advisable to save the contents of the pattern memory
onto a cassette tape (see the CASSETTE OPERATIONS chapter) to prevent loss
of patterns you wish to keep.
Pattern Clear (All Patterns: Except Presets)
Instrument Clear
A single instrument’s entire part may be immediately cleared from a pattern, when
the RX21 is in the pattern select mode, holding the CLEAR button while pressing
the appropriate instrument key. The LCD will show “CLEAR PTpp XXXX?” where
“pp” is the selected pattern number and “XXXX” is the instrument name, abbreviated.
(NOTE: you can also clear the accents from a pattern in this way, by pressing CLEAR
plus ACCENT).
If you decide you don’t want to clear the instrument, press the -1/NO button to
cancel the clear function.
If you want to clear the instrument, press the +1/YES key. The LCD will show the
“XXXXXX CLEARED!” display (where "XXXXXX” is the instrument name) followed
by the “SELECT PTN pp” display. If you have selected a preset pattern, the LCD
will show “PRESET PTN AREA!“, followed by the "SELECT PTN pp" display (preset
patterns are permanently stored and their instruments cannot be cleared).
