382 Chapter 24 EVP88
Note: Using Logic Studio’s plug-ins, you can process the upper notes differently to the
lower ones. With appropriate signal processing routings, you can, for example, add
some bass via an EQ in the left bass channel and apply a little echo to the higher notes.
Be creative!
Stretch and Warmth
The EVP88 is tuned to an equal-tempered scale. However, you can deviate from this
standard tuning, and stretch the tuning in the bass and treble ranges, much like
acoustic pianos (especially upright pianos). You can also modulate the tuning of each
note randomly.
Note: The tones of upright pianos, and to a lesser extent (due to their longer strings)
grand pianos have inharmonicities in their harmonic structure. The frequencies of the
harmonics are not exact, even multiples of the base frequency. They are only
approximate and are, in fact, a little higher. As a result of this, the harmonics of lower
(tuned) notes are more closely related to the main frequencies of the upper notes. Due
to the lack of strings, this inharmonic relationship is not true of electric pianos, nor the
EVP88. The stretch feature was included for situations where you may wish to use the
EVP88 in an arrangement alongside an acoustic piano.
Lower Stretch
Sets the deviation from the equal-tempered scale in the bass end of the sound. The higher
the value, the further down the low notes are tuned. At a setting of 0, the EVP88 is
tuned to an equal-tempered scale, with each octave down exactly halving the frequency .
Upper Stretch
Sets the deviation from the equal-tempered scale in the treble end of the sound. The
higher the value, the further up the high notes are tuned. At a setting of 0, the EVP88 is
tuned to an equal-tempered scale, with each octave up exactly doubling the frequency.
Warmth
Amount of random deviation from an equal-tempered scale. High values add life to
sounds.
Note: When applying Warmth and Stretch, you should consider that these parameters
may result in a detuned sound similar to a heavy chorus effect.
