CLICK ON EITHER THE PURPLE WORDS, OR BROWN WORDS
This feature allows you to adjust the pitch (tone) of the DX7 very slightly, so that it can be in tune with other instruments. It is a bit like the knobs used to tune the strings on a guitar. The range of adjustment is approximately one note, and the increaments are so fine, you are sure to be able to tune the DX7 perfectly to any other conventional instrument. Without this feature, the DX7 may sound horribly out of tune with other instruments.
POLY/MONO SCREEN 1of 2 SCREEN 2 of 2
RANGE = SELECT / DESELECT MODES
In POLY mode, you can play up to 16 notes simultaneously, therefore giving you the ability to play several notes at once, including chords.
POLY/MONO SCREEN 2 of 2 SCREEN 1 of 2
RANGE = SELECT - DESELECT MODES
In MONO mode, you can only play one note at a time. If you hold down two or more notes together, the last one you held down is played. You may think MONO mode is therefore rather pointless as it makes the DX7 less powerful than in Poly mode. However, MONO mode can be very expressive for ‘lead’ sounds, or replication of monophonic instruments such as flutes, oboes etc.
RANGE = 0-12
This can be set between 0 and 12. When set to zero, moving the Pitch Bend Wheel (in the ‘block’ next to the keys) up and down has no effect. When setting the value anywhere beteen 1 and 12, movement of the pitch bend wheel will cause a smooth increase in pitch, which can be useful for guitar type expressivenes etc. NOTE HOWEVER, IF BUTTON 4 (STEP) IS SET TO ANYTHING ABOVE 0, THE PITCH BEND RANGE IS SET AT 12 (which represents 1 octave of adjustnent), AND CANNOT BE ALTERED.
RANGE = 0-12
This can be set between 0 and 12. When set to zero, the pitch increase is smooth. When set to 1, there are small ‘steps’ which can be heard from movement of the Pitch Bend Wheel. When set to higher values, the steps are more noticeable. NOTE, AS SOON AS THE STEP VALUE IS SET TO 1 OR ABOVE, THE PITCH BEND RANGE IS AUTOMATICALLY SET TO 12 NOTES (1 OCTAVE).

RANGE = 1-16
It is unlikely that your DX7 actually has the word "MIDI" on button 8, but that's where you'll find it! Press '8' once, and you'll get the screen above. You cannot change the MIDI channel that the DX7 Transmits on, but here you can change the Receive channel.
MIDI SCREEN 2 of 2 SCREEN 1 of 2
RANGE = UNAVAIL / AVAIL
If you want the DX7 to Receive and Transmit sounds / patches over MIDI then you'll need to set the DX7 to "SYS INFO AVAIL". A third push of button '8' will say MIDI TRANSMIT? Press the "YES +1 ON" key, next to the Data Entry Slider to transmit MIDI SYS-EX info.
RANGE = YES / NO
If you have made any changes to one of the sounds, but you went out of the DX7's Editting system, you can get your editted sound back by selecting Edit Recall. This works, even after the DX7 is switched off (subject to battery condition).
RANGE = YES / NO
By selecting this option, the DX7 creat a 'blank', Initialized Sine Wave for you to start editing. This will not affect the sounds in the Internal Memory! They will be safe!!
RANGE = YES / NO
I have never done this, but this will format a RAM cartridge so that it can be used to store DX7 sounds / patches. The ROM cartridges CANNOT be formatted.
This feature checks the condition of the internal memory backup battery (Lithium CR2032, soldered into position). A good battery will show 3.0v. It is difficult to say how long this battery lasts, but it is apparent that the more the DX7 is used (i.e. plugged in and powered up), the battery condition improves over time. Removing / replacing this battery WILL result in all sounds being lost from your DX7, so make sure you have stored them safely!
RANGE = YES / NO
This feature will save the contents of the DX7's Internal Memory to a formatted Cartridge, allowing the sounds to be backed-up.
RANGE = YES / NO
This will load the contents of a ROM / RAM cartridge into the DX7's internal memory, erasing anything already held internally.
RANGE = 0-99
The modulation wheel sits next to the lowest key. This can be used to add various effects to a sounds, most often Vibrato. By adjusting the range, you adjust the amount the Modulation Wheel alters the sound.
RANGE = OFF - ON
If the modulation Wheel Pitch is set to OFF, then moving the Mod Wheel will not cause the Vibrato effect (the wheel may still cause other effects, depending on the individual sound's setting). By turning the Wheel Pitch ON, and ensuring the Mod Wheel Range (Button 17) is high enough, you'll get the Vibrato Effect.
