And what else?
The control panel of the P-45 is limited to the on/off button, the volume control, and the grand piano/function button. You can only select the grand piano sound number one directly, all other operations include the keyboard and the “Function” button. This also applies to selecting the other nine sounds.
A Fender Rhodes and an FM electric piano sound, two church organs, two harpsichord variants, a vibraphone, and a synthetic string sound complete the selection. The sound quality is satisfactory. In “Dual” mode, you can layer two sounds and adjust the volume. Further is a reverb effect with 4 types available, which in dual mode can be assigned to one of the two sounds. In “Duo” mode, “Grand Piano 1” becomes available in two independent keyboard halves in the same octave range – for four-handed playing. An integrated metronome is also included, but the P-45 does not offer a recorder.
Instead of a sustain pedal, the P-45 comes with a simple foot switch. You can play with it, but that is not exactly pleasant. If you want something better, you’ll have to buy the appropriate accessories (e.g. Yamaha FC3A).
