Using, Creating and Editing Voices Enhancing the Acoustic Realism of the Sound (iAFC) • NATURAL SOUND BOARD This enhances the acoustic realism of the sound by recreating the resonance characteristics of acoustic instruments. When used on a grand piano sound, it produces a more natural-sounding piano. The sound of the instrument itself is picked up by a microphone, and processed to create a virtual soundboard. • SPATIAL ENSEMBLE Effect This lets you experience the ambience and reverberation that are characteristic of performing on stage. Ambience and reverberation are also added to the performance of the musicians playing together with you, letting you enjoy the sensation of playing together on stage. The sound of the instrument itself and the sound of singing and other instruments played nearby is picked up by a microphone, and processed to simulate the spatial characteristics of performing together on stage. 3 Press one of the [5π†]-[7π†] buttons to select the iAFC setting (sub-type). 4 Press the [8π†] button to adjust the iAFC depth. Calibrating the iAFC Settings This automatically adjusts the sensitivity and response of iAFC so that the optimal iAFC effect will be obtained. Make sure to execute this operation when you select "NATURAL SOUND BOARD" or "SPATIAL ENSEMBLE." 1 Press the [F] (MIC CALIBRATION) button in the iAFC operation dis- play (page 76) to call up the calibration display. 2 Press the [G] (CALIBRATION START) button to begin calibration. When calibration begins, a fairly loud harpsichord note will sound four times at a fixed interval. Calibration will end in approximately two and a half minutes. Note on using calibration While calibration is being performed, do not make audible noises in the vicinity of the Clavinova. If any extraneous sounds are made in the vicinity of the Clavinova during calibration, the calibration may abort, and the settings will reset to their default values. If this occurs, you should perform the calibration once again. If the iAFC effect is slight or inaudible: If it seems that iAFC is not effective when playing back Songs or Styles, turn the iAFC feature off. 1 Press the [iAFC SETTING] button to call up the operation display. 2 Press the [1†] button to turn iAFC off. 1 2 1 2 3 4 5 6 7 8 CVP-309/307 Owner's Manual 77
