Buying Guide: What to Look for in a Fully Weighted Synth Keyboard
Key Action and Feel
The most important factor is the key action. Fully weighted keys simulate the resistance of an acoustic piano, with heavier bass keys and lighter treble keys. Graded hammer action is the gold standard, offering the most realistic feel. Some keyboards use semi-weighted keys, which are lighter but still provide more resistance than unweighted models. For the best playing experience, look for a keyboard with fully weighted, hammer action keys.
If you are unsure which type suits you best, our guide on the best weighted keyboard for beginners breaks down the differences in detail.
Sound Library and Polyphony
A rich sound library expands your creative possibilities. Look for keyboards with at least 128 tones, including grand piano, electric piano, strings, and synth sounds. Polyphony, the number of notes the keyboard can play simultaneously, is also crucial. Higher polyphony (128 notes or more) prevents notes from cutting off during complex passages or when using sustain.

Connectivity and Features
Modern keyboards offer USB-MIDI, Bluetooth, and audio outputs for connecting to computers, tablets, and speakers. Wireless MIDI is especially convenient for use with learning apps like Simply Piano. Built-in speakers are great for practice, while headphone jacks allow silent playing. Additional features like dual voice, split keyboard, and recording functions enhance your practice and performance experience.

Build Quality and Design
A sturdy build ensures longevity and stability during play. Furniture-style stands with key covers protect the instrument from dust and damage. Portable keyboards with lightweight designs are easier to move for gigs or lessons. Consider where you will use the keyboard most: at home, in a studio, or on the go.
