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 PORTAMENTO 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 adjacent buttons Until the display looks like this Then, ifnecessary, movethe slider down or press this button 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 indicate either "SUS-KEY P FOLLOW" or "SUS-KEY P RETAIN." Lets make sure it is set to "SUS-KEY P RETAIN." 4. Now play several notes, one after the other, whilestepping 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 original 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., GLISSANDO 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 FOLLOW mode. Push up the slider or press this button so the display indicates "SUS-KEY P FOLLOW" 2. Now press [GLISSANDO] to see whether the Glissando is turned on or not; the display will indicate one of two modes ,"GLISSANDO=ON"or "GLISSANDO =OFF." For now let's make sureit off , which means the DX7 is in PORTAMENTO rather than GLISSANDO mode. Then, if necessary, move the slider down or press this button so the display indicates "SUS-KEY P RETAIN" 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 sustain of the earlier notes also moves up to the latest note or chord played (FOLLOWS) instead of RETAINING the original pitch.
