Osc 1 Top [C–1…G9]
This sets the highest key on which Oscillator 1 will play.
Osc 2 Bottom [C–1…G9]
This sets the lowest key on which Oscillator 2 will play.
Osc 2 Top [C–1…G9]
This sets the highest key on which Oscillator 2 will play.
Hold [On, Off]
Hold is like permanently pressing down on the sustain pedal.
In other words, notes continue to sound as if you were
holding down the key - even after you lift your fingers from
the keyboard.
Unless the Sustain Level is set to 0 in Amp EG 1 (and Amp
EG 2 in a Double Program), the sound will play for the entire
length of the sample(s).
On (checked): The Hold function is enabled for the range
set by the Hold Bottom and Hold Top parameters, below.
Off (unchecked): Notes will play normally. This is the
default setting.
Using Hold with Drum Kits
Hold can be especially useful for drum programs, since it
lets the samples ring out naturally. In general, when you set
the
Oscillator Mode to Drums , it’s good to set Hold to On .
Once you’ve turned on Hold for a drum program, the
function is controlled on a note-by-note basis according to
settings within the selected Drum Kit.
If a key’s Enable Note Off Receive parameter (on the Voice
Mixer tab of the Drum Kit page) is unchecked, the note will
be held.
If the key’s Enable Note Off Receive parameter is checked,
it will not be held.
If you turn off Hold in the Program, no keys will be held -
regardless of their Enable Note Off Receive setting.
Using Hold with Acoustic Pianos
Hold is also useful for simulating the top octaves of an
acoustic piano, in which notes always sustain until they fade
out naturally, regardless of how long you hold the key.
The Hold Bottom and Hold Top parameters are designed
for exactly this purpose. They let you limit the effect of the
Hold parameter to a specific range of the keyboard.
Hold Bottom [C–1…G9]
This sets the lowest key affected by the Hold function.
Hold Top [C–1…G9]
This sets the highest key affected by the Hold function.
1–1e: Scale
Type [Equal Temperament…User Octave Scale15]
Selects the basic scale for the Program.
Note that for many of the scales, the setting of the Key
parameter, below, is very important.
Equal Temperament: This is the most widely used scale by
far, in which each semitone step is spaced at equal pitch
intervals.
Equal Temperament allows easy modulation, so that a chord
progression played in the key of C sounds roughly the same
as the same progression played in F#. Sacrificed, however, is
some of the purity of individual intervals offered by the
scales below.
Pure Major: In this temperament, major chords of the
selected key will be perfectly in tune.
Pure Minor: In this temperament, minor chords of the
selected key will be perfectly in tune.
Arabic: This scale includes the quarter-tone intervals used
in Arabic music.
Pythagoras: This scale is based on ancient Greek musical
theory, and is especially effective for playing melodies. It
produces completely pure fifths, with one exception, at the
expense of detuning other intervals– thirds in particular.
As much as Pythagoras might have like to do so, it’s not
possible to make all the fifths pure while also keeping the
octave in tune. For the sake of the octave, one of the fifths–
the interval from the sharp fourth degree to the sharp first
degree–is made quite flat.
Werkmeister (Werkmeister III) : This scale was one of the
many temperament systems developed towards the end of
the Baroque period. These “Well-Tempered” tunings were
aimed at allowing relatively free transposition–although
you’ll still notice that the different keys maintain their own
distinct characteristics, unlike Equal Temperament.
J.S. Bach was referring to these new scales in his title, “The
Well-Tempered Clavier.” As such, this group are particularly
appropriate for late baroque organ and harpsichord music.
Kirnberger (Kirnberger III) : This is a second “Well-
Tempered” tuning, dating from the early 18th century.
Slendro: This is an Indonesian gamelan scale, with five
notes per octave.
When Key is set to C , use the C, D, F, G and A notes. Other
keys will play the normal equal-tempered pitches.
Pelog: This is another Indonesian gamelan scale, with seven
notes per octave.
When Key is set to C , use the white keys. The black keys
will play the equal tempered pitches.
Stretch: This tuning is used for acoustic pianos.
User All Notes Scale: This is a user-programmed scale with
different settings for all 128 MIDI notes. You can set up this
scale in GLOBAL >Controllers/Scales– User Scale page.
User Octave Scale 00–15: These are user-programmed
scales with settings for each of the 12 notes in an octave.
You can set them up in GLOBAL > Controllers/Scales– User
Scale page.
Key (Scale Key) [C…B]
Selects the key of the specified scale.
This setting does not apply to the Equal Temperament ,
Stretch , and User All Notes scales.
If you’re using a scale other than Equal Temperament, the
combination of the selected scale and the
Key setting
may skew the tuning of the note. For example, A above
middle C might become 442 Hz, instead of the normal
440 Hz. You can use the GLOBAL Mode’s
Master Tune
parameter to correct this, if necessary.
