result in its return to center value plus or minus
one.
• Note: the pitch bend off zone or zero window
created in software is wider than this value.
These values are arbitrary and do not equal MIDI values, although
these values are used to create the MIDI value through software
programming, (e.g. a 129 pitch wheel center value read during
power up, would equal pitch bend 64, and if pitch bend center was
104 at power up it would still equal a pitch bend value of 64).
2.16.9 WHEEL AND SLIDE TESTS:
• Move each control up and down and the display should
list what the control is and a value that should
range from 0 down, 255 up.
2.16.10 ALPHA WHEEL:
• Spin the knob. It should indicate
0, 1, 2, 3, 0, 1,
2, 3,
etc., when rotated clockwise.
2.16.11 BUTTON TESTS:
• Press each button and the LCD should display
function of each button.
• Mode buttons will also blink their respective LEDs.
2.16.12 KEY TESTS:
• Press the Hi C key. The LCD will display "KEY C7 96
C7 96".
• Translation; the first of two key contacts makes
about one half travel and is identified as a
"c"
key, 7th octave which is MIDI note 96. The second
contact makes near the end of travel and is also a
"c"
key, 7th octave, MIDI note 96. Each key press
will be correctly identified by note, octave, and
pitch.
2.16.13 MONO PRESSURE TESTS:
• A.K.A. after touch or second touch. Press each key
to down and you will feel a resistance at the down
stop position. Pressing harder will compress the
down stop which is a pressure sensitive variable
resistor strip.
• The LCD will display PRESSURE
=
nnn(O
=
minimum and
255
=
maximum) •
2.16.14 PEDAL TEST:
• Insert a pedal cable plug into pedal jack 1 or 2,
the LCD will display pedal 1 or 2.
• Insert control pedal into its jack, the LCD will
display CONTROL PEDAL
=
nnn(O
=
minimum and
gradually increase to 255
=
maximum) as the pedal is
depressed.
TO EXIT SCANNER DIAGNOSTICS, PRESS "EXIT" AND "ENTER" TOGETHER.
