5.8.8 FX1 & FX2 Channels
The	
  FX1	
  and	
  FX2	
  return	
  channels	
  are	
  provided	
  to	
  return	
  signal	
  to	
  the	
  Mixer	
  that	
  you	
  have	
  sent	
  
through	
  the	
  FX	
  bus	
  plugin	
  slots.	
  The	
  Mute,	
  Solo,	
  gain,	
  and	
  pan	
  controls	
  on	
  these	
  channels	
  
function like those on the other channels.
Note that you can insert VST instruments into the FX1 and FX2 channels if desired. These
channels	
  receive	
  MIDI	
  inputs,	
  and	
  can	
  be	
  used	
  for	
  additional	
  layering	
  of	
  instruments.	
  However,	
  
if	
  you	
  configure	
  a	
  Preset	
  in	
  this	
  manner,	
  you	
  will	
  no	
  longer	
  be	
  able	
  to	
  use	
  the	
  FX	
  channel	
  as	
  a	
  
send.
5.8.9 Main
Stereo
Output Channel
A Main channel gain control is available for adjusting the master volume of the configured
Preset.
The Main channel is the last stage in the audio routing structure. It outputs the sum of the
mixed audio signals.
The Main channel features three plugin slots. Main plugin slots are well suited to effects such as
equalizers	
  and	
  limiters,	
  which	
  can	
  add	
  some	
  polish	
  to	
  the	
  final	
  sound	
  of	
  your	
  Preset.	
  A	
  limiter	
  
can	
  also	
  help	
  prevent	
  clipping	
  in	
  the	
  output	
  of	
  the	
  V-‐Machine.	
  
The	
  gain	
  and	
  pan	
  controls	
  in	
  the	
  Main	
  channel	
  operate	
  exactly	
  like	
  those	
  in	
  the	
  other	
  Mixer	
  
channels.	
  
5.8.10 BPM Control
Using	
  the	
  BPM	
  control	
  above	
  the	
  master	
  fader,	
  you	
  can	
  set	
  the	
  tempo	
  of	
  the	
  VFX	
  Application’s	
  
internal	
  MIDI	
  clock.	
  This	
  tempo	
  will	
  be	
  used	
  by	
  any	
  plugin	
  that	
  can	
  respond	
  to	
  external	
  tempo	
  
sync.	
  For	
  it	
  to	
  work,	
  the	
  tempo	
  sync	
  must	
  be	
  switched	
  on	
  in	
  the	
  plugin.	
  (See	
  the	
  plugin’s	
  
manual	
  for	
  details.)	
  
This	
  field	
  corresponds	
  to	
  the	
  Tempo	
  parameter	
  in	
  the	
  Preset.	
  To	
  see	
  the	
  Tempo	
  parameter,	
  
scroll	
  the	
  parameter	
  field	
  in	
  the	
  V-‐Machine	
  (either	
  the	
  hardware	
  unit	
  or	
  the	
  V-‐Machine	
  Pane	
  in	
  
the software) almost all the way to the left.
5.8.11 Time Signature
A few plugins that have tempo-‐based features (such as LFOs that can be synced to MIDI clock
messages)	
  may	
  also	
  be	
  able	
  to	
  request	
  the	
  time	
  signature	
  of	
  the	
  host.	
  The	
  V-‐Machine’s	
  Mixer	
  
provides	
  a	
  time	
  signature	
  parameter	
  for	
  this	
  purpose.	
  You	
  can	
  set	
  the	
  denominator	
  of	
  the	
  time	
  
signature	
  (the	
  lower	
  number)	
  to	
  2,	
  4,	
  8,	
  or	
  16	
  and	
  the	
  numerator	
  (the	
  upper	
  number)	
  to	
  any	
  
number between 1 and 32, depending on the meter of your song,
5.8.12 Master MIDI Channel
The	
  MIDI	
  Channel	
  setting	
  in	
  the	
  Mixer	
  controls	
  the	
  channel(s)	
  on	
  which	
  the	
  Mixer	
  will	
  respond	
  
to	
  MIDI	
  control	
  messages.	
  This	
  parameter	
  is	
  available	
  only	
  in	
  the	
  VFX	
  Application;	
  it	
  cannot	
  be	
  
set	
  from	
  the	
  V-‐Machine’s	
  panel.	
  Normally	
  the	
  Mixer	
  MIDI	
  channel	
  can	
  be	
  left	
  set	
  to	
  ALL.	
  There	
  
might	
  be	
  a	
  specific	
  situation,	
  however,	
  in	
  which	
  you	
  would	
  need	
  to	
  set	
  the	
  Mixer	
  to	
  respond	
  on	
  
a	
  particular	
  channel	
  so	
  that	
  you	
  can	
  re-‐use	
  the	
  same	
  CC	
  messages	
  on	
  different	
  channels	
  for	
  
other	
  purposes.	
  (This	
  is	
  especially	
  likely	
  to	
  happen	
  if	
  your	
  hardware	
  controller	
  has	
  only	
  one	
  CC	
  
source, such as a mod wheel, with which to send these messages.)
Program change messages that arrive on the Mixer’s channel will be used by the Mixer to
