DX7 OUTLINE

The DX7 can be used to play pre-programmed voices, pre-programmed voices can be edited to alter their character, or completely new voices can be created from scratch.  Newly created voices can be memorized for future use.
To accomplish all this, the DX7 has four main operating modes:

• PLAY-MEMORY SELECT Mode
  This is the normal performance mode, and the mode in which pre-programmed voices can be selected.
  
  
• FUNCTION Mode
  This mode permits setting parameters pertaining to the effect of the controllers (thumbwheel, foot controller, breath controller, key after touch) and is also used for loading and saving data.
  
  
• EDIT Mode
  This mode permits editing existing voice data to create new sounds as well as creation of entirely new voices
  
  
• STORE Mode
  Edited or newly created voices can be programmed into the memory in this mode.
  
  

All functions of the DX7 are performed in one of the above modes.  Proper understanding of the functions of each mode is the key to successful operation of and performance with the DX7.

1. VOLUME
   This controls the output level of the DX7 and at the same time controls the volume of the headphones.
   
   
2. DATA ENTRY
   This combination of keys and linear control is used to enter and modify data.
   
   
   
3. MODE SELECT KEY
   Selects the operating mode, "operators" (these will be explained later) and memory protect functions.
   
   
   
4. DISPLAY PANEL
   This Liquid Crystal Display panel displays the parameters in each mode and the name of the selected pre-programmed voice.
   
   
   
5. VOICE/PARAMETER SELECT KEY
   These keys select either the voices in the instrument's internal memory or those in an external voice cartridge.  The same keys are also used to select parameters in the FUNCTION or EDIT modes.  One key can have a maximum of four different functions.
   The function of these keys is determined by the MODE SELECT key.
   
   
   
6. VOICE CARTRIDGE
   External voice cartridges can be plugged into the receptacle in the DX7 panel.  The DX7 is supplied with two ROM (pre-programmed) voice cartridges, each contraining 64 voices.
   An optional RAM (user-programmable) voice cartridge can contain 32 voices.
   
   
7. PITCH BEND WHEEL
   The pitch bend range is set in the FUNCTION mode.  The pitch bend wheel then permits upward and downward pitch bend throughout the set range.
   
   
8. MODULATION WHEEL
   The modulation depth range is set in the function mode.  The modulation wheel then permits variation of modulation depth throughout the set range.
   
   
9. KEYBOARD
   The DX7 has a 61-key keyboard with 16-voice polyphonic capability (a monophonic mode is also selectable).
