Editing DX Part Parameters
FeedBack
Settings: -7 to +7
Explanation:
• Sets the level of feedback.
• Feedback is a function where a portion of the output of an operator is returned
back to the operator again, where it is used to modulate the operator itself. Feed-
back can be used to change the brightness (amount of overtones) of the sound.
• Because this setting acts as an offset added to the output level set for the voice in
the PLG100-DX, it indirectly changes the timbre of the voice. When this param-
eter is set to zero, the voice will remain as is. Setting it to +1 or more will make the
sound brighter (increase the overtones), while setting it to -1 or less will darken it
(decrease the overtones).
PortaMd (Portamento Mode)
Settings: flw/ftm, rtn/fgr
Explanation:
• Portamento is an effect that produces a smooth glide between two notes of differ-
ent pitch.
• The way in which the Portamento effect is applied is set with the Portamento
Mode. However, there will be a large difference in the effect depending on the
Poly/Mono setting for the selected voice.
When Poly Mode is set:
• When flw/ftm is set, the Portamento effect will also be applied to the sustained
sound from when the sustain pedal is depressed, and to the lingering sound after
the hand is removed from the key. The sound will change to the pitch of the next
note played.
• When rtn/fgr is set, the Portamento effect will not be applied to the sustained
sound from when the sustain pedal is depressed, or to the lingering sound after the
hand is removed from the key.
When Mono Mode is set:
• When flw/ftm is set, normal Portamento effect is applied.
• When rtn/fgr is set, the Portamento effect is only applied when the next key is
pressed while the first key is held down.
• In the DX7, each is called as follows:
flw: Sus-key P Follow
ftm: Full Time Porta
rtn: Sus-key P Retain
fgr: Fingered Porta
PortaStep (Portamento Step)
Settings: 0 to 12
Explanation:
• Sets the way in which the pitch is changed by the Portamento effect.
• The 0 value sets a normal continuous change.
• Setting 1 to 12 changes sound according to the scale. For example, if 1 is set, the
change is by semitones, if 2 is set, it is by whole tones.
