AP-650

Features

Touch response

Enables dynamic playing by differing sound intensity and sound properties in response to the keystroke. A light, slow stroke sounds soft and gentle, while a hard stroke sounds loud and powerful.

Audio recording function

The audio recording function enables users to record in professional CD quality onto a USB storage medium or SD card (depending on the instrument). The recording can be burned onto CD or played back on every common medium.

Automatic accompaniment

Automatic accompaniment of the melody, which simplifies the left hand's part. A single key (CASIO chord) or several keys (full-range chord) can produce chords and control the harmonies of the "backing band".

Brilliance

Digital effect used for piano timbres in particular; the sound becomes brighter and more powerful (brilliance).

Chorus

Digital effect used to double the timbre, making the sound more vibrant, broader and much livelier. This effect is used for digital piano or organ timbres in particular.

Damper resonance

The nuances generated by pressing the damper pedal are authentically replicated.

Duet mode

Duet mode is designed, just like the "Split" function, to divide the keyboard into two zones.
However, the range and the timbre are identical in this mode. This feature allows two musicians to play a piano duet or to practice together on one instrument.

Hammer response

The specific 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 heads and the time that elapses until they hit the strings are directly linked to the pitch and striking intensity on the keyboard. CASIO Hammer Response technology reproduces this mechanical property of an acoustic instrument.

Key-Off Simulation

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.

Lid Simulation

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.

Line-in (L/mono,R)

Input (L/R with standard sockets) to connect an audio source with line level (e.g. another instrument or sound card) to an instrument.

Line-out (L/mono, R)

Audio output on line level to connect the instrument to other professional devices, such as a PA or mixer console.

Metronome

The metronome beats in the preset time signature as a guide for keeping to the right tempo.

Octave shift

This setting shifts the octaves on the keyboard to the more comfortable middle zone when playing pieces of music that require users to play on the very low or high zones of the keyboard.

Reverb

Digital effect that adds reverberation to the timbre.

String resonance

The unique CASIO string resonance system precisely simulates the resonating and interacting piano strings for all 88 keys. The nuances generated by pressing the damper pedal ("damper resonance") are authentically replicated.

Transpose

The transpose function shifts the scale on the keyboard by semitones, for instance so that an F would be played on the C key.

USB port (PC)

Port for a USB cable to connect the instrument to a PC or Mac for the purpose of MIDI and/or data transfer.
