Base Key (BASE KEY): OFF, C1 - C6 This parameter sets the "BASE KEY" for an external MIDI synthesizer used to control the PITCH parameter (the MIDI OUT terminal of the synthesizer must be connected to the REX 50 MIDI IN terminal, and the REX50 must be set to receive on the MIDI channel on which the synthesizer is transmitting). If, for example, the BASE KEY parameter is set to C4, pressing the C3 key on the synthesizer (C3 is one octave lower than C4) will set the pitch change value to - 12. Pressing D4 on the keyboard would produce a pitch increase of one whole-tone (+ 2). If a key more than an octave higher or lower than the BASE KEY is pressed, the resultant pitch change setting will still be within the - 12 to + 12 range, as shown in the illustration below. If the BASE KEY parameter is set OFF, pitch cannot be controlled via the MIDI IN terminal.

PITCH CHANGE B / PITCH CHANGE B makes it possible to produce two independently pitch-shifted output notes in addition to the direct signal, so you can actually create three-part harmonies with a single input note. Both pitch-shifted notes appear at the center of the stereo sound field (i.e. they are output equally to the L and R OUTPUT jacks. 1st Pitch Shift (1 PITCH): -12 - + 12 Sets the pitch of the first pitch-shifted note between one octave below ( - 12) and one octave above ( + 12) the input note. 1st Fine Tuning (1 FINE): -100 - + 100 Permits fine tuning of the first pitch-shifted note in 1-cent steps. 1st Delay Time (1 DLY): 0.1 - 400.0 ms Determines the time delay between input of the original note and output of the first pitch-shifted note. 2nd Pitch Shift (2 PITCH): - 12 - + 12 Sets the pitch of the second pitch-shifted note between one octave below ( - 12) and one octave above (+12) the input note. 2nd Fine Tuning (2 FINE): - 100 - + 100 Permits fine tuning of the second pitch-shifted note in 1-cent steps. 2nd Delay Time (2 DLY): 0.1 - 400.0 ms Determines the time delay between input of the original note and output of the second pitch-shifted note. 18

Base
Key
(BASE
KEY):
OFF,
C1
-
C6
This
parameter
sets
the
"BASE
KEY"
for
an
exter-
nal
MIDI
synthesizer
used
to
control
the
PITCH
parameter
(the
MIDI
OUT
terminal
of
the
synthesizer
must
be
connected
to
the
REX
50
MIDI
IN
terminal,
and
the
REX50
must
be
set
to
receive
on
the
MIDI
channel
on
which
the
synthesizer
is
transmitting).
If,
for
example,
the
BASE
KEY
parameter
is
set
to
C4,
pressing
the
C3
key
on
the
synthesizer
(C3
is
one
octave
lower
than
C4)
will
set
the
pitch
change
value
to
—
12.
Pressing
D4
on
the
keyboard
would
produce
a
pitch
increase
of
one
whole
-tone
(+
2).
If
a
key
more
than
an
octave
higher
or
lower
than
the
BASE
KEY
is
pressed,
the
resultant
pitch
change
setting
will
still
be
within
the
—
12
to
+
12
range,
as
shown
in
the
illustration
below.
If
the
BASE
KEY
parameter
is
set
OFF,
pitch
cannot
be
controlled
via
the
MIDI
IN
terminal.
