23: BREATH RANGE, EG BIAS
This function permits breath pressure applied to the BC-1 breath controller to directly
control the amplitude or timbre of the voice, according to settings of the corre-
sponding voice parameters which will be covered in CHAPTER IV. The LFO has
no effect-only your breath pressure directly affects the amplitude or timbre of the
voice.
The data range is from 0 to 99. At 0, EG bias is OFF. A setting of 99 permits the
greatest amplitude or timbre variation to be produced through the breath controller.
Data is entered using the DATA ENTRY control and –1/+1 buttons. Once this
function is called, subsequent presses on the 23 button increment the data value.
24: VOICE NAME
This function moves the LCD cursor from left to right, allowing you to name any
new voice or sound you have created before storing it. When button 24 is pressed,
the cursor flashes over the first letter in the name of the voice presently occupying
a space in the INTERNAL memory. The DATA ENTRY slider or –1/+1 buttons
are used to increment or decrement the alphabetical selection (A to Z), along with
many other symbol selections, while subsequent presses on the VOICE NAME
CURSOR button move the LCD cursor to the immediate right.
KEY SET
During either of the normal DX27 play modes, pressing the KEY SHIFT button
instantly transposes the pitch of the entire DX27 keyboard up or down to a key
programmed using this function. When KEY SHIFT is engaged, the letter “K” will
appear at the left side of the LCD display until the KEY SHIFT button is pressed
again, returning the keyboard to normal pitch.
Pressing this button in the FUNCTION mode permits a shift to the desired pitch
when the KEY SHIFT button is pressed while in either of the play modes.
The transpose range for the KEY SHIFT function is plus or minus two octaves. The
data range is from –24 to +24, with 0 corresponding to standard keyboard pitch.
Each increment corresponds to a shift in pitch of one semitone-a setting of 2 would
therefore raise the pitch of the entire keyboard a whole step.
Immediately after calling the KEY SET function, data can be entered simply by
pressing a key on the keyboard within a plus/minus two-octave range of C3 (middle
C). The pressed key then assumes the pitch of C3, and all other keys are adjusted
accordingly. Pressing the A2 key, for example, produces a setting of -3. Pressing
a key higher than C5 results in a +24 setting. This method of data entry, can only
