Base Key (BASE KEY): OFF, C1 — C6
This parameter sets the "BASE KEY" for an externa! MIDI
synthesizer used to control the PITCH parameter (the MIDI
OUT terminal of the synthesizer must be connected to the
SPX50D MIDI IN terminal, and the SPX50D 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 in-
crease of one whole-tone (42). 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 parame-
ter is set OFF, pitch cannot be controlled via the MIDI IN
terminal.
+1~ +12 range is
repeated
Pitch can be changed
over a + 12 range with
the BASE KEY in
the center.
- 1--- 12 range is

PITCH CHANGE B makes it possible to produce two independ-
ently 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).
ist 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 — 4100
Permits fine tuning of the first pitch-shifted note in 1-cent
steps.
1st Delay Time (1 DLY): 0.1 — 400 milliseconds
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 milliseconds
Determines the time delay between input of the original note
and output of the second pitch-shifted note.
