PORTAMENTO & GLISSANDO IN POLY MODE
Sustain: Key Pitch Retain
1. Press [PORTAMENTO TIME] and use the [DATA
ENTRY] controls to set a time of 80, as indicated in
the LCD window. (If the TIME is set at or near zero,
there will be no discernable portamento or glissando
effect, regardless of what you do with the other POR-
TAMENTO functions. Higher values than 80 are OK,
but will take more of your time than necessary when
exploring these functions.)
Then adjust this
slider or the adja-
cent buttons
Until the display looks like this
2. Now press [GLISSANDO] to see whether the Glis-
sando is turned on or not; the display will indicate
one of two modes , "GLISSANDO = ON" or "GLISSAN-
O = OFF."
For now let's make sure it off
, which
D
means the DX7 is in PORTAMENTO rather than
GLISSANDO mode.
Then, if necessary, move the
slider down or press this but-
ton so the display indicates
"GLISSANDO=OFF"
The display should look like this
3. Now press [PORTAMENTO-MODE] to see which of
two possible modes is engaged; the display will indi-
cate either "SUS-KEY P FOLLOW" or "SUS-KEY P
RETAIN." Lets make sure it is set to "SUS-KEY P
RETAIN."
Then, if necessary, move the
slider down or press this but-
ton so the display indicates
"SUS-KEY P RETAIN"
4. Now play several notes, one after the other, while-
stepping on the SUSTAIN pedal. Play a bass chord,
then a high note. Observe that the pitch glides from
the previously played note(s) to the next note(s), but
the sustain of the earlier notes remains at their origi-
nal pitch. Experiment with this effect.
Sustain: Key Pitch Follow
Assuming you have just completed the previous
instructions, the DX7 is in "SUSTAIN: KEY PITCH
RETAIN" mode, with SUSTAIN mode engaged (i.e., GLIS-
SANDO turned off), and a moderate PORTAMENTO
time of 80. Now let's explore "SUSTAIN: KEY PITCH
FOLLOW" mode.
1. Since the DX7 is already in PORTAMENTO mode,
press the [>] DATA ENTRY button or push up the
slider to set the DX7 to SUSTAIN-KEY PITCH FOL-
LOW
mode.
Push up the slider or press this
button so the display indicates
"SUS-KEY P FOLLOW"
The display should look like this
2. Now play several widely spaced notes or chords, one
after the other, while stepping on the SUSTAIN pedal.
Observe that the pitch again glides from the previ-
ously played note(s) to the next note(s), but the sus-
tain of the earlier notes also moves up to the latest
note or chord played (FOLLOWS) instead of RETAIN-
ING the original pitch.
