Preliminary 

2.3 Function Data: Per-Patch or Global 

 
This  setting  determines  whether  or  not  there  is  one  global  set  of  Function  Parameters  or  if  the 
Function Parameters are set on a per-patch basis. 
 

FUNCTION CONTROL 
Func/Patch= OFF 

 
The traditional setting for the original DX7 is that there is one global set of Function Parameters.  
You  can continue  this tradition  by  setting Func/Patch  (function per  patch)  to OFF.    If  you  would 
prefer to save Function data with each patch, then set Func/Patch to ON.   
 
In addition to the regular DX7 function parameters 
 

 

Poly/Mono, Portamento, Aftertouch, Pitchbend, Modulation Wheel and Breath Controller 

 
the new parameters 
  

 

Volume, Active Keyboard Zone and Voice Stacking 

 
are  saved  with  each  patch  when  this  is  enabled.  If  you  don’t  utilize  Function/Patch,  then  the 
Volume  setting  isn’t  really  of  much  use  since  it  will  be  global  and  there  is  already  a  dedicated 
analog Volume slider.on the DX7. 
 
 
 

2.4 Function Data: Initialization 

 
This  sets  the  Function  Data  to  a  known  good  state.  This  should  be  performed  after  board 
installation  and  whenever  dubious  function  data  is  found  (such  as  might  happen  after  loading 
from a ROM or RAM cart or Sys Ex receive or changing the battery) 
 

FUNCTION CONTROL 
Func Data INIT?_

 

 
To initialize the Function Data, simply locate this menu item and press the +/Yes button.   
 
 
 

2.5 MIDI Transmit Channel (global parameter) 

 
All  of  the  MIDI  settings  are  global,  in  that  they  are  NOT  saved  with  a  patch.    They  are  saved 
overall for the synthesizer. 
 

FUNCTION CONTROL 
MIDI Ch OUT = 1

 

 
The MIDI note data, patch changes, etc. will be transmitted on the MIDI Channel specified here.  
Using the Data slider or the Yes/No buttons, select the MIDI OUT channel you want, the range is 
1 to 16. 
 
Note: The MIDI IN channel is established via the standard DX7 Function button 8.
