Introducing the Casio AP-650M Celviano Range Digital Piano
AiR is the acronym for “Acoustic and intelligent Resonator”, which is CASIO’s newly developed multi-dimensional sound production. This sound production and other innovations constitute the common core of the new digital piano technology. The result is the unprecedented, natural-sounding digital reproduction of a grand piano’s playing and sound properties.
The number of voices (tones) that a musical instrument can generate at the same time. Polyphony reflects a digital instrument’s capability. This is particularly significant when playing on an advanced level, using the pedals or using several timbres at the same time.
The II in Scaled Hammer Action II indicates that CASIO developed an improved keyboard. “Hammer action” means that the digital piano’s keyboard is weighted with small hammers in order to provide realistic touch sensitivity, just like that of a real grand piano. “Scaled” means that the weight of the keys decreases from the low to the high keys, just like with an acoustic instrument.
The Casio AP-650M’s new keyboard action mechanism features three sensors per key that detect the intensity with which the key is struck to reproduce the response of a grand piano. This precise measurement also allows extremely sophisticated playing techniques at a high repetition speed.
The fine keyboard design offers the same luxurious, haptic and optic features as genuine ebony and ivory. The carefully roughened surface texture prevents fingers from slipping, even when playing for a long time.
High Resolution Velocity is a new technology by CASIO, which is approved by the MIDI Manufacturers Association. Instead of 127 steps, this technology provides 16,000 steps of the keyboard’s touch response allowing to realise every nuance of grand pianos’ dynamics.
In the top of the line models, the piano features a real lid that can be opened or closed. This reinforces the impression of an acoustic piano.
The Lid Simulator simulates the different sound characteristics (brighter/duller) when playing with an open or closed piano lid. There are four simulation levels to choose from depending on personal taste: open, removed, half open or closed.
The Casio AP-650M’s unique string resonance system ensures precise simulation of the sympathetic and interacting piano strings for all 88 keys. The nuances generated by pressing the damper pedal (“damper resonance”) are authentically replicated.
The Key-off Simulator ensures authentic end-of-note characteristics. Whether legato or staccato, the long time it takes for notes to fade when the keys are released softly is emulated with as much richness of nuance as the short fade-out time of notes when keys are released quickly.
The nuances generated by pressing the damper pedal are authentically replicated.
The feel of an acoustic piano also comes from the delay between striking the key and the sounding of the string. The size and mass of the hammer head and the time that elapses until it hits the strings are directly linked to the pitch and striking intensity on the keyboard. This mechanical property of an acoustic instrument is reproduced by The Casio AP-650M’s “Hammer Response” technology.
The audio recording function enables the user to record in professional CD quality onto a USB storage medium or SD card (depending on the instrument). The recording can be burnt or played back on every common medium.
