■ REV1 (Reverb 1) GROUP
• PCM — Mono Pitch Change
PITCH CHANGE 1 makes it possible to produce two independently pitch-shifted output notes in addition to the direct signal, so you
can create three-part harmonies with a single input note.

PCA (1st Pitch Shift:-12 —+12)
PCB f2nd Pitch Shift: -12 — 4-121
These two parameters set the pitch of the first or second
pitch-shifted note between one octave below (-12) and one
octave above (+12) the input note.
FINA fist Fine Tuning: -100 — +1001
FINB f2nd Fine Tuning: -100 — +1001
Permit fine tuning of the first or second pitch-shifted note in
1 -cent steps (1 cent is 1/100th of a semitone).
DLYA (1st Delay Time: 0.1 —1300 ms)
DLYB f2nd Delay Time: 0.1 —1300 ms)
The DLYA and DLYB parameters determine the time delay
between input of the original note and output of the first or
second pitch-shifted note.
PBAL /Pitch Balance: A=50 — A=1. A=B. B=1. B=501
Sets the balance between the 1st and 2nd pitch-shifted
notes, a setting of "A=50," for example, produces only the
sound of the 1st note. "A=B” produces both notes in equal
balance. "A=50" produces only the sound of the 2nd note.
LPF (Low-pass Filter Cutoff Frequency: 1.0kHz — 11kHz.
THRU1
Sets the cutoff frequency of the low-pass filter. The "THRU"
setting bypasses the filter.
FB f Feedback: -100 — +100%)
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 settings of
the PCA and PCB parameters.
KEY (Base Kev: OFF. Cl — C61
This parameter sets the "base key" for an external MIDI
synthesizer used to control the amount of pitch change
produced (the MIDI OUT terminal of the synthesizer must be
connected to the FX900 MIDI IN terminal, and the FX900
must be set to receive on the MIDI channel on which the
synthesizer is transmitting). If, for example, the 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 PCA (or PCL in the PCS program) sound, and the
lower note determines the pitch of the PCB (or PCR in the
PCS program) sound.
If a key more than one 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 illustratfon below.
If the KEY parameter is set OFF, pitch cannot be controlled
via the MIDI IN terminal.
MIX fMIxIno: 0 — 100%)
Sets the balance between the direct and pitch-changed
sound.
LVL /Output Level: -°°. -30 — +6 dB)
Determines the output level of the PCM effect.
