Left Feedback Gain (L.F.B.): -99 – +99%
Right Feedback Gain (R. F. B): -99 – +99%
When this parameter is set to 0, only a single pitch-shifted
sound is produced after the DELAY time has elapsed. As the
value of this parameter is increased, however. more and more
delayed repeats are produced. each pitch-shifted up or down
from the previous repeat according to the setting of the PITCH
parameter.
n 30. PITCH CHANGE 3
PITCH CHANGE 3 offers the "thickest" and most complex
sound by allowing the creation of three pitch-shifted notes in
addition to the direct sound.
1st Pitch Shift (1 PITCH): -24 – +24
2nd Pitch Shift (2 PITCH): -24 – +24
3rd Pitch Shift (3 PITCH): -24 – +24
Set the pitch of the first, second or third pitch-shifted note
between two octaves below (-24) and two octaves above (+24)
the input note.
1st Fine Tuning (1 FINE): -100 – +100
2nd Fine Tuning (2 FINE): -100 – +100
3rd Fine Tuning (3 FINE): -100 – +100
Permit fine tuning of the first, second or third pitch-shifted
note in 1-cent steps.
1st Delay Time (1 DLY): 0.1 – 1400.0 milliseconds
2nd Delay Time (2 DLY): 0.1 – 1400.0 milliseconds
3rd Delay Time (3 DLY): 0.1 – 1400.0 milliseconds
Determines the time delay between input of the original note
and output of the first, second or third pitch-shifted note.
1st Level (1 LEVEL): 0 – 100%
2nd Level (2 LEVEL): 0 – 100%
3rd Level (3 LEVEL): 0 – 100%
These parameters determine the levels of the first, second and
third pitch-shifted notes.

n 31. MONO PITCH
The MONO PITCH program produces a single pitch-shifted
note. The PITCH parameter can be varied while playing
(using an external controller, for example) to provide smooth,
real-time pitch variation.
Pitch Shift (PITCH): -24 – +24
Set the pitch of the pitch-shifted note between two octaves
below (-24) and two octaves above (+24) the input note.
Fine Tuning (PITCH FINE): -100 – +100
Permit fine tuning of the pitch-shifted note in 1-cent steps.
Delay Time (DELAY): 0.1 – 1400.0 milliseconds
Determine the time delay between input of the original note
and output of the pitch-shifted note.
Feedback Gain (FB GAIN): -99 – +99%
When this parameter is set to 0, only a single pitch-shifted
sound is produced after the DELAY time has elapsed. As the
value of this parameter is increased, however. more and more
delayed repeats are produced, each pitch-shifted up or down
from the previous repeat according to the setting of the PITCH
parameter.
PARAMETERS ACCESSED BY THE INT PARAM
KEY
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
SPX900 MIDI IN terminal, and the SPX900 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). When two keys are pressed, the
highest note determines the pitch of the 1 PITCH or L PITCH
sound, and the lower note determines the pitch of the 2 PITCH
or R PITCH sound. With the STEREO PITCH program the
last note pressed takes priority. If a key more than two octaves
higher or lower than the BASE KEY is pressed, the resultant
pitch change setting will still be within the -24 to +24 range,
