VOICE EDIT MODE
CONTROLLER: PITCH BEND RANGE
JOB 29
Summary: Sets the maximum pitch bend range.
Settings: 0 ... 12
Procedure: Use the [DATA ENTRY] control, [-1/NO]
and [+1/YES] keys, or numeric and [ENTER] keys
to set the required pitch bend range.
Details: Each increment from "0" to "12" represents
a semitone. A setting of "0" produces no pitch
bend. A setting of "12" allows a maximum pitch
bend of plus or minus one octave, while a set-
ting of "4" allows a maximum pitch bend of plus
or minus a major third.
If the MIDI controller used is a keyboard,
pitch bend is normally controlled via its pitch
bend wheel.
CONTROLLER: AFTER TOUCH PITCH BIAS
JOB 30
Summary: Sets the maximum pitch variation range
achievable via after-touch control.
Settings: -12 ... +12
Procedure: Use the [DATA ENTRY] control, [-1/NO]
and [+1/YES] keys, or numeric and [ENTER] keys
to set the required after touch pitch bias range.
Details: Each increment represents a semitone. A
setting of "0" produces no pitch variation. A
setting of "+12" allows a maximum pitch vari-
ation of one octave up, while a setting of "-12"
allows a maximum pitch variation of one octave
down corresponding to after-touch key pressure.
CONTROLLER: RANDOM PITCH RANGE
JOB 31
Summary: Sets the amount of random pitch vari-
ation produced each time a note is played.
Settings: 0 ... 7
Procedure: Use the [DATA ENTRY] control, [-1/NO]
and [+1/YES] keys, or numeric and [ENTER] keys
to set the required random pitch range.
Details: When this function is set to a value other
than "0," the pitch changes randomly each time
a note is played. The random pitch change is ap-
plied independently to each note in a chord. A
setting of "7" produces the greatest amount of
random pitch change.
This function is ideal for simulating the
sound of instruments like the clavichord, string
sections or other ensembles in which the pitch
of each note is rarely in perfect tune with the
others.
