Alesis Concert Digital Stage Piano

Alesis Concert — Full-Size 88-Key Digital Piano for Home, Stage, and Classroom

The Alesis Concert is a full-featured 88-key digital piano built to give pianists a complete playing range in a portable, affordable package. Semi-weighted keys with adjustable touch response sit beneath a clean control layout, and 10 built-in voices cover the timbres most players reach for first. This model is the right choice for keyboardists who need an 88-note instrument with realistic sound, onboard speakers, and battery-powered flexibility.

What Sets the Concert Apart in the Sub-€400 Digital Piano Segment

Lesson Mode divides the 88-key bed into two zones playing the same pitch and voice, letting a teacher and student share one instrument without reaching across each other. Battery operation from six D-cell cells frees the keyboard from the wall socket, a rare feature at this tier that opens up busking and classroom use. Pedal Resonance adds sympathetic-string-style behaviour to the sustain pedal response.

Keyboard Action and Touch Response

Semi-weighted keys are lighter than a fully graded hammer-action bed, which reduces finger fatigue during long practice sessions while still offering enough resistance for expressive dynamic playing. Adjustable touch sensitivity lets each player match the keyboard to their own strength.

• Keys: 88 full-sized semi-weighted — complete seven-octave-plus range for standard repertoire
• Touch Sensitivity: Fixed, Soft, Medium, Hard — four curves for beginners and stronger-fingered players
• Velocity-sensitive action — dynamics follow how hard each key is struck, not just on/off triggering

Sound Engine — Voices, Polyphony, and Effects

A 128-note polyphony ceiling is generous for layered performances and sustained pedal chords. The voice set covers the staples a working pianist needs without burying them in presets they will never use.

• Built-in Voices: 10 — Acoustic Piano, Bright Piano, Electric Piano, Harpsichord, Drawbar Organ, Church Organ, Synth, Strings, Bass, Clavi
• Polyphony: 128-note maximum — sustains complex passages without note drop-out
• Onboard effects engine — 5 reverb types (Room, Hall, Church, Delay, Pan Delay) plus Chorus, Flanger, and Rotary, all editable from the front panel

Connections, Speakers, and Power

Built-in speakers and a quiet-practice headphone output cover most home and stage scenarios without extra hardware.

• Built-in Speakers: 20 W total — fills a small room without external amplification
• Headphone Output: 6.35 mm TRS — mutes internal speakers for silent practice
• USB-MIDI via USB Type B — connects to a computer for educational software and virtual instrument plug-ins
• Stereo Outputs: RCA left/right — routes to a mixer, amplifier, or recording interface
• Sustain pedal input (6.35 mm) — pedal ships in the box, so expressive playing is possible from the first session
• Power: 12 V DC adapter (included) or 6 × D-cell batteries — cable-free playing anywhere
• Dimensions & Weight: 1283 × 291 × 87 mm, 7.10 kg — slim profile and light enough for one-handed carry

Who Should Choose the Alesis Concert

This keyboard is the right choice for beginner and intermediate pianists who want a full 88-key range without committing to a heavier hammer-action instrument. Adult learners appreciate the four touch curves, which let them tune the feel as their strength builds. Teachers benefit from Lesson Mode, which removes the awkwardness of sharing a single keyboard during a lesson. Travelling players will appreciate the battery option that frees the instrument from the nearest wall socket.
