VA-76 – Phrase Parameters
5.3 Phrase Parameters
As you know, there are some parameters you usually
set immediately after sampling an audio phrase and
before saving it to disk. “Executing” those changes
transforms such a phrase into a VariPhrase (a process
we call “encoding”). VariPhrases are the audio “tracks”
you can use in combination with the Arranger/Song
Composer. Their main feature is that, while their pitch
usually changes as expected, the tempo remains the
same for all notes – and is synchronized to the Arran-
ger/Song Composer.
Even though the following parameters also modify the
selected phrase, you can reverse those changes by
selecting other settings. (By contrast, a “truncated”
phrase cannot be restored to its original length.) Be
aware, though, that these changes need to be saved to
disk if you want them to take effect each time you load
such a phrase. Also note that these parameters are
only available for User phrases – not for the phrases
in ROM.
1. Select the phrase to be edited by pressing
[GROUP], [USER] and a number button [1]~[8].
2. Press the [FUNCTION MENU] button.
3. Press the [ VariPhrase] field.
4. Press the [Select Phrase] field.
You can also select the Phrase Parameter page by hold-
ing the [USER] button and pressing [Phrase Parame-
ter] on the page that appears then:
The display now looks more or less as follows:
The following parameters can be set by touching the
corresponding field and by using the [TEMPO/DATA]
dial .
Pitch
Press the [Pitch] field to select the following page.
Coarse Tune
(–24~+24) This parameter is similar to the Original
Key parameter on the Edit page (see page 74). The
main use for this parameter will probably be to trans-
pose a phrase in octave steps depending on which keys
you use for playing it.
This may greatly enhance the realism of the audio
phrases you use. Being able to play a phrase at any
pitch indeed means two things:
• the VariPhrase processor has to adapt the tempo of
each note that is different from the Original Key.
• while changing the pitch in realtime, the processor
also shifts the Formant to avoid the dreaded “chip-
munk” effect (see also page 48). These shifts are usu-
ally very good, so that you may not even notice that
the phrase is being played way above or below the
pitch of the original audio signal.
As a rule, however, you should use this parameter for
ensuring that the original pitch of the audio phrase
falls within the keyboard range where you’ll be most
likely to play the phrase. This will further improve the
sound quality.
Note: You could also select other values to create fifths inter-
vals with respect to the Upper1/Upper2 (or Lower1/Lower2)
part(s).
B3 B5
(1) If this key corresponds to the
sampled pitch,…
(2)… while the phrase will
be played in this range,…
(3)… set Coarse
Tune to “–12”.
