Yamaha REX50 - Manual (Page 19)

Base Key (BASE KEY): OFF, Cl - C6
This parameter sets the "BASE KEY" for an exter­
nal MIDI synthesizer used to control the PITCH
parameter (the MID! OUT terminal of the synthesizer
must be connected to the REX50 MIDI IN terminal,
and the REX50 must bd 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 makes it possible to produce two in^
dependently 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 ( - 1 2 ) and one octave above
(- 1 - 1 2 ) the input note.
1st Fine Tuning (1 FINE): -100 — -HlOO
Permits fine tuning of the first pitch-shifted note in
1-cent steps.
1st Delay Time (1 PLY): 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 bet­
ween one octave below ( - 1 2 ) and one octave
above ( + M ) the input note.
2nd Fine Tuning (2 FINE): - 100 - -H 100
Permits fine tuning of the second pitch-shifted note
in 1-cent steps.
2nd Delay Time (2 PLY): 0.1 - 400.0 ms
Determines the time delay between input of the
original note and output of the second pitch-shifted
note.
