midi piano keyboard

Key counts range from 61 to 88 keys. Action types include semi-weighted (waterfall and standard), heavy-hammer/hammer-action designs, and fully weighted hammer-action keybeds.

Connectivity includes USB‑MIDI, standard 5‑pin DIN MIDI ports, class‑compliant USB for Mac/Windows/iOS, and Bluetooth on some models (audio and/or MIDI).

Built-in tutor and demo songs, LED learning lights on some consoles, teaching modes, recording/playback, scale and chord modes, arpeggiators, and arranger-style split/layer functions.

Expressiveness ranges from semi-weighted keys (waterfall or standard) that support technique and ease of play, to heavy‑hammer and full hammer‑action keybeds designed to emulate acoustic piano resistance and dynamic touch response.

Pedal setups vary by model: compact/portable keyboards often include a single sustain or modulation pedal (commonly a basic plastic sustain pedal), while many 88‑key digital pianos are listed with a triple‑pedal set. Exact pedal types and inclusions are specified per product.

Portable keyboards typically include built-in stereo speakers (examples list 2×3W speakers), while console-style instruments have larger integrated multi‑speaker systems. Most keyboards include a headphone jack; some packages include headphones, and one console lists dual headphone outputs for private practice.

Common accessories include a power adapter, a sustain pedal (often a basic plastic pedal), headphones, and USB cables. Some listings also include extras such as keyboard stickers, a 420D carry bag, a triple‑pedal unit for 88‑key models, or a headphone adapter.

Most models use AC power with an included adapter or power supply; several do not require batteries. One console lists “Battery: Optional, Not Included.” Warranty information shown on multiple 88‑key listings indicates a 1 Year Limited Warranty in the product details.
