CHAPTER 13. ELECTRIC GRAND PIANO.
This is a simulation of a Yamaha CP80 electric baby grand piano. The original instrument also featured a built-in equalizer with a
“Brilliance” lever switch, and a tremolo effect. The Seven reproduces only the sound of the piano as found at the jack output with all EQ
knobs at middle position and the brilliance lever on the high position. To obtain more EQ options, just turn on Seven's internal EQ. And,
of course, the tremolo can be added with FX1.
The parameters you find in the EDIT PIANO page are:
 HAMMER CUTOFF: Cutoff frequency of the low-pass filter applied to the hammers. Since this is a physical modeling instrument,
we're not talking about a filter applied to the whole sound, but only to a single element of the virtual piano. By increasing this
parameter you'll notice that the attack component will result brighter, even though this brightness is not always added to the
body of the decaying sound.
 HAMMER RESONANCE: Resonance amount of the low-pass filter applied to the hammers.
 HAMMER OFFSET: This parameter adjusts the horizontal alignment of all hammers in relationship with the strings. In the center
position, all hammers are perfectly aligned; if the position is changed, the whole harmonic content of each note could change in
an unpredictable way. This greatly affects what's known as the “voicing” of a grand piano.
 HAMMER WIDTH: Set the size of the virtual hammers. A bigger size results in a fuller sound but will increase the volume, which is
not always a good thing. Imagine playing a drum with a thin stick, it sounds good and balanced. Now use a thicker stick, it
sounds a bit louder but you may not like the timbre as some of the harmonic content is dampened by the bigger mass that
strikes the drum head. Same with the strings.
 STRING DAMPING: Set the amount of damping of all strings, i.e. the loss of higher harmonics during the decay phase.
 STRING DETUNING: This parameter adjusts the slight detuning between the strings. This also affects the voicing, adjust it at small
steps.
