Independent shopping perspective
The Korena take
With 88 full-size GHS keys, the P-45 keeps weighted piano action in a compact 25 lb portable digital piano. Its lower register takes a heavier touch than its upper register, and sensitivity can be set to hard, medium, soft, or fixed. AWM stereo sampling, ten voices, layering, reverb, and chorus provide its sound options. USB MIDI supports computer connections, while Duo mode, a metronome, onboard speakers, headphones, and sustain-pedal support cover lessons, private practice, and everyday playing.
Strong match
Who this is for
- Side-by-side lessons using Duo mode’s two matching pitch ranges.
- Quiet practice in shared spaces through the 1/4-inch stereo headphone output.
- Connecting to compatible recording, notation, or music-education software via USB MIDI.
Consider the trade-offs
When to look elsewhere
- Players who require more than the 10 onboard voices.
