Reference Miscellaneous CP300 Settings-Other Settings Parameters Touch Response 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. A B TouchResponse Vel= 64 Fixed NO YES C D Settings: Light Medium Heavy Fixed A soft playing touch results in a relatively loud sound. The volume level tends to be consistent. Standard touch response. 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. 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 Default setting: Medium Tune 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. A Tune C A3=440.0Hz B NO YES D Setting range: A3 = 427.0 Hz - 453.0 Hz (0.1 Hz steps) Default setting: A3 = 440.0 Hz Piano Tuning Curve 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. A B PianoTuningCurve NO YES Stretch C D Settings: Stretch Flat Tuning curve particularly for pianos, with higher octaves slightly "stretched." Tuning curve in which the frequency relationships are precisely duplicated in all octaves. Default setting: Stretch Scale 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. A Scale C BaseNote=C PureMajor B NO YES D Settings: Equal PureMajor PureMinor Pythagorean MeanTone Werckmeister Kirnberger 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. 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. 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. 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. 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. 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 68 CP300 Owner's Manual
