Auto Pitch
Here’s another interesting effect that can either be
used as gimmick or to ensure that even the flattest of
renditions suddenly sounds in tune. Of course, the voice
will sound somewhat “artificial”, because the emphasis
is on tuning here. However, even if you just speak the
words of a song, it will be sung just the same.
(1) Press the [AUTO≈PITCH] button.
(2) Start song playback and say something into the
microphone (don’t sing).
Sounds like a very popular effect, doesn’t it?
(3) Press and hold the [AUTO≈PITCH] button.
The display changes to:
Let us begin with the most important parameter: the
notes that will be used by the AUTO PITCH function.
That is what you specify via the AUTO PITCH ASSIGN
fields.
(4) Set the TRACK value to select a song part.
The “4” setting usually corresponds to the melody
part of a Standard MIDI File, and is thus the most
likely candidate, but feel free to select “1”~”3” or “5”~
”16” to use another part as melody.
If you want to play the melody yourself, press the
[LEFT] or [RIGHT] field (or both) and play the desired
notes, while you speak (or sing) into the microphone.
Note: Selecting LEFT and/or RIGHT will set the TRACK parame-
ter to “Off”.
Use the OCTAVE parameter to shift the pitch of the
Auto Pitch notes up to 2 octaves up or down.
(5) Press the [VIBRATO] field to add some “wobble” to
the Auto Pitch sound.
This vibrato effect is not linked to the Voice-FX
vibrato, and can thus be set separately (see below).
(6) For more refined control over the Auto Pitch voice,
press the [EDIT] field:
Though they are not linked to their namesakes on the
Voice-FX Edit page, most parameters on this page will
look familiar. Therefore, please see above for the
explanations of GENDER and VIBRATO RATE,
DEPTH, RISE TIME, and DELAY TIME.
(7) Press the parameter field whose value you want to
edit and set the desired value with the
[DATA÷ENTRY] dial.
Note: Parameter fields can also be selected using the DATA
ENTRY [√][®][ß][†] buttons.
(8) Press the [PORTAMENTO] field to switch on this
effect.
“Portamento” means that the pitch doesn’t change in
clearly defined steps: it produces glides from one
note to the next.
Use the PORTAM TIME parameter to specify the
speed at which those glides are carried out (0~127).
The higher the value, the slower the transitions.
Note: To keep your settings, you must write them to a User
Program.
(9) Press [EXIT] to leave this page (or [Back] to modify
other Auto Pitch settings).
Using the Vocoder
A Vocoder is an effect that combines spoken words
with sounds, thus creating the impression that the
instrument that produces the sounds can talk. As this
relies on complex filtering effects, the character of the
sound used as “carrier” can change dramatically.
