The Membrane 

 

The front panel membrane of the 

ATC–X 

contains an array of switches, with each colored 

pad  located  atop a  single  switch.  To  access  any  function  or  parameter; press  with  light  to 
moderate force on the desired switch pad. 

  
Some  of  the  switch  pads  have  dual  or  multiple  functions;  which  when  pressed  more  than 
once  access  the  next  function.  In  addition,  a  few  functions  are  accessed  by  pressing  and 
holding one switch pad, then immediately pressing another.  
 
A  complete  list  of  the  multiple  and  combination  switch  pad  operations  is  listed  on  the 
"QUICK REFERENCE GUIDE" sheet. 
 
*Note that the display blinks momentarily after each press, informing you that your action has 
been recognized.  

 
 

The Rotary Encoder 
 

The  main  user  interface  in  programming  the

  ATC-X 

is  the  rotary  encoder;  which  turns 

smoothly in either direction for complete control. After a switch pad is pressed you will use 
the  encoder  in  almost all  operations  to  edit  or  change  any  desired  function  or  parameter. 
Edits to certain sound parameters are transmitted as MIDI controller data. 

 
 

Reading the Display 
 

The 3 digit L.E.D. on the 

ATC–X 

is used to display parameter values, function assignments, 

and  all  operations  in  an  alphanumerical  format.  Abbreviations  are  used  for  most  of  the 
function  assignments;  refer  to  the  "MASTER  SYMBOL  KEY"  on  the  "QUICK  REFERENCE 
GUIDE" sheet for explanations of the three digit abbreviations. 
 
Three periods or dots also appear which represent the following: the left two periods show 
that the programmed patch has been edited, and the right period shows that a MIDI note has 
been received. 
 
If you are ever confused as to whether you are looking at a patch number or parameter value, 
press 

exit/bank

exit/bank and you will return to the Patch Number Display Mode.  

See PROGRAM.
