Parameters
This allows you to specify the touch response of the
CP300’s keyboard, or change how the sound responds to
the way you play the keys.
Settings:
Default setting: Medium
This allows you to finely tune the pitch of the entire
instrument—a useful feature when playing the CP300
along with other instruments or CD music.
Setting range: A3 = 427.0 Hz – 453.0 Hz (0.1 Hz steps)
Default setting: A3 = 440.0 Hz
This allows you to specify a tuning curve, Stretch or Flat,
for the Piano Voices groups (Grand Piano 1, Grand Piano 2
and Mono Piano). Actual piano tuners often employ stretch
tuning, extending the upper octaves of the piano slightly to
compensate for the perception of the human ear in the
higher range. The Flat setting is an acoustically perfect
tuning, to be used if the stretch-tuned piano Voice sounds
out of tune with other instrument Voices.
Settings:
Default setting: Stretch
This allows you to select different scales or tuning systems
for the instrument. Equal Temperament is the most
common contemporary piano tuning scale. However,
history has known numerous other scales, many of which
serve as the basis for certain genres of music. You can
experience these tunings with the CP300.
Settings:
Setting range: C, C#, D, Eb, E, F, F#, G, Ab, A, Bb, B
For scales other than Equal, a root note must be specified using
the B [– (NO)]/[+ (YES)] buttons.
Default setting: Equal
Touch Response
Light A soft playing touch results in a relatively loud sound.
The volume level tends to be consistent.
Medium Standard touch response.
Heavy The keys must be played very strongly to generate
loud volume. This setting is best for a wide dynamic
range and optimum expressive control of the sound,
from pianissimo to fortissimo.
Fixed No touch response. The volume level will be the same
regardless of how strongly you play the keys. Use the
B [– (NO)][+ (YES)] buttons to set the fixed volume
level. Setting range of the fixed volume level:
1 – 127

Stretch Tuning curve particularly for pianos, with higher
octaves slightly “stretched.”
Flat Tuning curve in which the frequency relationships are
precisely duplicated in all octaves.
Scale
Equal The pitch range of each octave is divided equally
into twelve parts, with each half-step evenly
spaced in pitch. This is the most commonly used
tuning in music today.
PureMajor These tunings preserve the pure mathematical
intervals of each scale, especially for triad chords
(root, third, fifth). You can hear this best in actual
vocal harmonies—such as choirs and a cappella
singing.
PureMinor
Pythagorean This scale was devised by the famous Greek
philosopher and is created from a series of
perfect fifths, which are collapsed into a single
octave. The 3rd in this tuning are slightly
unstable, but the 4th and 5th are beautiful and
suitable for some leads.
MeanTone This scale was created as an improvement on the
Pythagorean scale, by making the major third
interval more “in tune.” It was especially popular
from the 16th century to the 18th century. Handel,
among others, used this scale.
Werckmeister The Werckmeister and Kirnberger scales were
improvements on the mean-tone and
Pythagorean scales. The main feature of these
scales is that each key has its own unique
character. The scales were used extensively
during the time of Bach and Beethoven, and
even now are often used when performing period
music on the harpsichord.
