11.1
Symptom: No Sound
Things to check:
●
Is the V-‐Machine powered up?
●
Are the outputs of the V-‐Machine connected to your audio system?
●
Is your audio system powered up?
●
Is
the
channel
of
your
audio
mixer
to
which
the
V-‐Machine
is
attached
turned
down
or
muted?
●
Have you connected a MIDI cable from the output of your keyboard to the V-‐Machine’s
MIDI input?
●
Is your keyboard transmitting on the MIDI channel that the V-‐Machine expects to
receive on?
●
Is the V-‐Machine’s internal Mixer channel for the active Preset turned down or muted?
11.2
Symptom: Sound Is Distorted
Things to check:
●
Is
the
signal
from
the
V-‐Machine
overloading
the
input
of
your
sound
system?
Try
turning
down
the
output
volume
of
the
V-‐Machine
Mixer
using
the
Mixer
Master
Gain
parameter
or
the
Output
Gain
parameter
in
the
Global
System
Settings
menu,
or
lower
the
input
trims
on
your
sound
system’s
channels.
●
Are you using so many simultaneous plugins that the V-‐Machine’s processor can’t keep
up?
Scroll
the
parameter
setting
all
the
way
to
the
left,
to
VFX
Buffer
Size,
and
try
increasing
the
number
of
samples
in
the
buffer.
(Increasing
the
buffer
size
will
also
increase
the
amount
of
time
the
V-‐Machine
needs
to
respond
to
incoming
MIDI
messages.)
●
Is the signal from an instrument plugin overloading the input of an effect plugin in the
same
mixer
channel?
Find
the
master
output
gain
parameter
for
the
instrument
plugin
and
try
lowering
it.
