88-key weighted Graded Hammer Standard (GHS) action, 10 voices, 64-note polyphony, MIDI via USB to HOST, 6W + 6W amplifier and built-in speakers, foot switch, music rest and power supply included. The feel of the GHS keyboard gradually changes according to the register, so that it feels heavier when playing bass parts and lighter when playing treble parts. The piano also features a keyboard with a natural feel, with black keys that feature a matte finish for authentic piano playing close to that of an acoustic piano. The P-45 has improved on the traditional AWM synthesis to deliver real piano sounds. AWM is a technology that uses digital recordings of sources, such as actual instruments, and allows you to enjoy grand piano reverberation wherever you are. Slim and stylish form with a depth of less than 30 cm, the instrument requires little space, and at only 11.5 kg with its speaker attached, it can be easily moved anywhere in your home or even used for performance outside.
