Product Description
Yamaha P-145 — Stylish, expressive digital piano
The Yamaha P-145 blends compact design with realistic piano feel and a clear, musical sound, making it an excellent choice for students, home players and gigging musicians who need portability without sacrificing playability. Its 88-key GHC (Graded Hammer Compact) keyboard delivers weighted action that simulates an acoustic piano’s heavier bass and lighter treble response, enabling nuanced dynamics and expressive performances.
Under the hood, the P-145 features Yamaha's CFIIIS piano samples and a 64-note polyphony engine that preserves note clarity during complex passages. Four reverb types and damper resonance add natural ambience and realism, while Sound Boost increases presence for small-room playback or performance. The instrument includes Dual and Duo modes for layering sounds or splitting the keyboard for teacher-student practice, plus ten preset voices covering grand piano, electric pianos, organ, strings and more.
Connectivity is practical and modern: a USB TO HOST port supports MIDI and stereo audio transfer, useful for recording, DAW work or linking to smart device apps like Smart Pianist and Rec'n'Share. The P-145 also offers a standard headphones jack that mutes speakers for late-night practice, a sustain (SUSTAIN) jack for pedals, and (on the P-145 model) a PEDAL UNIT jack for the optional LP-5A three-pedal unit with half-pedal control.
Setup and daily use are straightforward — the [GRAND PIANO / FUNCTION] button plus designated keys provide quick access to touch sensitivity, transpose, metronome and other on-board functions. An Auto Power Off feature helps conserve energy, while backed-up settings retain key preferences. The instrument ships with a footswitch, music rest and recommended AC adaptor (PA-150 in many regions).
For teachers and learners, included preset songs, demo songs and the Duo mode support practice and instruction. Maintenance is simple: no tuning required, and cleaning requires only a soft dry cloth. Yamaha’s global support network and downloadable manuals, Smart Pianist support, and compatibility with common accessories (stands, headphones, pedals) make ownership convenient and well-supported.
Notes
- The P-145 keeps a compact footprint and light weight (about 11.1 kg), making it easy to move and fit into small spaces.
- Use the official AC adaptor and recommended cables to avoid damage and interference.
- Optional LP-5A pedal unit unlocks half-pedal and full three-pedal functionality.
