FOOTSWITCH
The last soft control is the optional foot-switch. 
A footswitch allows hands-free control of these 
effects parameters:
• Tap to set the BPM
• Turn the Effect on & off
• Select  between the  two Effects  Processors 
(same as the DECK switch).
The footswitch can also assist with looping and 
recording functions.  THESE ARE SHOWN IN THE 
GROUPS SECTION.
 SEE “FOOTSWITCH DIAGRAM” 
ON PAGE 51.
EFFECTS CUEING
You  can cue  an effect before you  turn  it  on so 
that  you  can  check  how  it  sounds  before  you 
bring it into the mix. Button B5 turns the Effect 
Cue  on  or  off.  Note that  if you  turn  Effect Cue 
on,  it  stays on  even when  you  switch between 
effects.
  For  an  Effect  Cue  to  be  heard  in  the 
headphones,  the  Effect  Processor  must  be 
selected,  Effect  Cue  must  be  on  and  the  Cue 
Pan  and  Master Cue  controls  must be  in  the 
correct position.
  For instance, with a track playing in PGM 1:
1. Select Processor 1 to choose your Effect.
2. Select B1 to route PGM 1 to the Effect.
3. Select B5 to Cue the Effect in your phones.
4. Select B6 to send the Effect to the Master.
5.  Echo  Effects  are  post-fader,  so  the  fader 
needs to be up to send the Effect a signal. Other 
Effects do not rely on the fader.
  The Effects Cue for an Effect inserted in Main 
or  Aux  Bus  is  only  heard  in  the  headphones  if 
the  Master  Cue  switch  is  on.  The  Hold  Echos 
are the only Effects that cannot be heard in the 
headphones unless it is on and also sent to the 
Master.

BASIC EFFECTS CONTROLS
The selected effect is edited with the remaining 
soft  controls.  The  function  of  some  controls 
depends on the selected Effect. Specic control 
functions are detailed for each Effect. The basic 
operation of these controls is outlined here:
B5  Toggles  the  Effects  Cue  On  / Off.  This  is  a 
global setting and does not change state when 
toggling  between  Effects  Processors.  See  the 
Effects Cueing section to the right for details.
B6 toggles the selected Effects Processor On / 
Off.
J1  and  J2  joysticks  may  operate  as  transform 
switches  or  be  used  to  control  effects 
parameters.  J1  and  J2  each  feature  an  eight-
position joystick, a push switch and a green 
mode indicator light.
•  If  the  indicator  light  is  off,  the  associated 
joystick operates as a transform switch.
•  If  the  green  indicator  light  is  on,  the  joystick 
is  assigned  to  an  effect parameter  as shown 
on  the  following pages.  Pressing  the  joystick 
toggles between the two modes of operation. 
If a second function is not available, pressing 
the joystick has no effect. SEE “CONTROLLING 
SCRATCH LIVE FROM THE TTM57SL” ON PAGE 34.
P1  and  P2  may  be  used  to  control  Effect 
parameters, each consisting of a rotary encoder, 
a push switch and a green mode light.
