 The same program might sound different because
of differences in the performance's tone parameters,
timbre parameters, master effects, and EQ settings.
 Return the edited parameter to its original value, or
change parameters of differing values to the same
value.
 If a timbre's tone parameters (p. 31) have been
edited (this can happen by receiving certain CC#s),
you can return to the saved settings by reselecting
the program.
 If timbre parameters have been edited (this can
happen by receiving certain CC#s), you can return
to the saved settings by reselecting the performance.
Alternatively, you can execute Initialize
Performance to initialize the parameters of the
performance. After doing either of the above steps,
reselect the performance.
* The timbre parameters include Volume, Pan (Pre),
Pan (Post), OSC Select, OSC Mode, Portamento,
Octave, Transpose, Detune, and UsePrgScl.
In Performance Edit, can't change the value
of a timbre parameter such as "MIDI
Channel" or "Status"
 Some parameters can't be edited while notes are
playing, either locally or from MIDI. If the damper
pedal is held down, or if its calibration is incorrect,
notes may be sustaining even if they aren't audible.
 Are you using a damper pedal with a polarity that
does not match the "Polarity (Switch Polarity)"
setting? p. 52
 In some cases, this problem can be solved be
executing the command "HalfDmpr Calib (Half
Damper Calibration)". p. 53
Effects and EQ
Effects or EQ are not applied
 Could the Effect SW "ALL IFXs," "MFX1&2," or
"EQ" be Off? p. 49
 Could No Effect be selected as the effect type?
 On the front panel, press the MODULATION
button or REVERB/DELAY button to select an
effect. p. 20
 In the edit page, select something other than No
Effect for "IFX," "MFX1(Mod)," and "MFX2(Rev)."
p. 30, 44
 Could the Effect SW settings "All IFXs," "MFX1&2"
or "EQ" be Off? p. 49
 In a performance, if the master effect still does not
apply even when you've raised the timbre's
"Send1(Mod)" and "Send2(Rev)" settings, are the
"Return1" and "Return2" settings from the master
effect raised? p. 49
Could the "Send1(Mod)" or "Send2(Rev)" settings
for each program oscillator used by the timbre be
lowered? p. 30
Note: The actual send level is determined by
multiplying the send of each of the program's
oscillators by the send setting of the timbre track.
Troubleshooting Audio output
Insert effect is not applied
 Could you have changed the program's category
when saving it? p. 46
 The STRINGS timbre does not have an insert effect.
 Could the IFX "On/Off" setting be Off? p. 45
The blinking speed of the ORGAN FAST/
SLOW button does not match the speed of
the rotary speaker simulator
 If you switched the speed of the rotary speaker
simulator by operating the joystick in the +Y
direction, the ORGAN SLOW/FAST button's
blinking speed will not change. Press the ORGAN
SLOW/FAST button to change the blinking speed.
Alternatively, operate the joystick once again in the
+Y direction to switch the rotary speaker simulator's
speed.
The ORGAN SLOW/FAST button does not
blink
 The ORGAN SLOW/FAST button blinks only for
ORGAN programs in which 63 Rotary SP is selected
as the insert effect.
MIDI
The PS60 does not respond to incoming MIDI
data
 Are all MIDI cables or USB cables connected
correctly? p. 12, "PS60 USB-MIDI Setup Guide"
 Is the MIDI data being received on the channel on
which it is being transmitted? p. 50, 30
The PS60 does not respond correctly to
incoming MIDI data
 Are the MIDI Filter settings "Prog Chg," "Bank
Chg," "AfterTouch," "Ctrl Chg," and "SysEx"
respectively turned On? p. 51, 32
 Does the PS60 support the types of messages that
are being sent to it? p. 63
Incorrect response to program change
messages
 Is the "Bank Map" setting correct?  PG p.134
 Program changes on the global MIDI channel
correspond to performances.
 The programs of the timbres will not switch.
Pedal does not respond correctly
Damper response is wrong
 Execute the "HalfDamper Calib" command (Global
- Command) to correctly adjust the sensitivity of the
half damper pedal. p. 53
