Osc.sync
Transpose
Voice name
Each DX7 II operator produces a sine wave. The Osc.sync (oscillator synchronization)
parameter determines whether or not the sine waves all begin at phase 0. If they do, the
timbre of a voice will evolve in the same way each time a key is pressed.
off Do not start operators' sine waves at phase 0 for each keypress.
on Start operators' sine waves at phase 0 for each keypress.
The following diagram illustrates the effect of this parameter.

If
this parameter is off, the tonal transition will be smoother between notes played legato
and more abrupt between notes played staccato. This is often effective for acoustic
instruments.
Normally, the pitch of the DX7 II keyboard is set so that the key marked with the small
triangle corresponds to middle C (C3) with a frequency of 262 Hz. The transpose
parameter allows you to shift the pitch of this key (and thus the entire keyboard) for any
voice by half steps to as much as two octaves above or below the standard pitch.
C
1 Assign the pitch Cl to the marked key.
C 5
Assign the pitch C5
to
the marked key.
This parameter is useful for adapting the keyboard range to suit the voice. For example, a
flute or piccolo patch would be well served by transposing the keyboard pitch up. A bass
sound would need a downward transposition.
This parameter lets you name the voice you are editing with up to ten symbols. The
available symbols (letters, numbers, etc.) are printed in brown below the Data Entry,
Voice Mode Select, EG Copy, Performance, and number buttons.
To enter a name, move the cursor to the voice name parameter and hold down the Edit
button, which has the word "Character" printed below it. While holding the Character
button, enter the desired symbols by pressing the respective buttons. Pressing the Internal
button while holding the Character button will produce lower case letters. The Cartridge
button will produce upper case letters.
