Troubleshooting
There is a time lag after playing the
keyboard before your software synthesizer
produces sound
By its nature, a software synthesizer produces sound via the sound card of your
computer. There will be a time lag before the sound of the software synthesizer is
actually played back from the sound card, and this is known as the "latency."
There will always be some latency for any combination of software synthesizer and
sound card, but by using the appropriate combination of sound card and sequencer
software settings, it is possible to reduce the latency to the point where it is not a
problem for actual use.
The following settings are generally effective ways to reduce the latency.
• Decrease the audio buffer size of your DAW software
• Decrease the buffer size for your sound card
In either case, refer to the owner's manual for your sequencer software or sound card
for the specific procedure.
When using the PCR with DAW software,
you're unable to send system exclusive
messages to an external sound module
You'll need to make settings in your DAW software to enable the function that passes
system exclusive messages through to your sound module. For details on how to
enable this, refer to the owner's manual for your software.
Bender lever does not apply pitch bend or
modulation
The PCR lets you assign MIDI messages to the bender and modulation controllers of
the bender lever. If such assignments have been made, the lever won't produce pitch
bend or modulation.
Set the bender and modulation to NO ASSIGN as described in Canceling an
assignment (NO ASSIGN) (p. 67).

Aftertouch not applied
The PCR lets you assign a MIDI message to the aftertouch controller. If such an
assignment has been made, aftertouch will not be applied.
Set aftertouch to No Assign as described in Canceling an assignment (NO ASSIGN)
(p. 67).
