488 Chapter 27 EVD6
Warmth
Amount of random deviation from an equal-tempered scale. High values add “life” to
sounds. It can be useful for simulating an instrument which has not been tuned for a
while, or for slightly “thickening” a sound. When playing chords, the Warmth parameter
creates the warm detuning or beating effect between the chord’s notes. Click-hold, and
use your mouse as a slider to adjust.
Stretch
The EVD6 is tuned to an equal-tempered scale. As a deviation from this standard
tuning, you can stretch the tuning in the bass and treble ends of the sound. This
simulates the way stringed keyboard instruments such as pianos are tuned, attempting
to find a more constant tuning balance between high and low notes. The stretch
feature was included for situations where you may wish to use the EVD6 alongside
acoustic pianos. When arranged in conjunction with an orchestra or synthesizers, the
stretch tuning facility should not be used. Click-hold, and use your mouse as a slider to
adjust.
Note: The tones of clavinets, harpsichords, and pianos have inharmonicities in their
harmonic structure. The frequencies of these overtones (harmonics) are not exact,
whole-number multiples of the base frequency, as Pythagorean theory dictates. They
are only approximate and are, in fact, a little higher. The overtones of lower (tuned)
notes, therefore, are more closely related to the main frequencies of the upper notes.
Also see “Stiffness/Inharmonicity” on page 496.
Note: When applying Warmth and Stretch, you should consider that these parameters
may result in a detuned sound, which is similar to the overuse of a chorus effect.
Pressure
On an original D6, applying pressure (aftertouch) to a depressed key raises the pitch
slightly. The Pressure parameter allows you to do this, or alternately lower the pitch by
pressure. Click-hold, and use your mouse as a slider to adjust. Range: −1.00 to +1.00
