What is the difference between a MIDI controller and a digital piano?

A MIDI controller sends MIDI data (note signals) but produces no sound on its own — it requires a computer, interface, or sound module to generate audio. A digital piano has built-in sound and speakers. MIDI controllers are designed for studio production; digital pianos are designed for playing and practice. Some instruments blur the line, but 88-key MIDI controllers are primarily studio tools.

Does the Arturia KeyLab 88 Mk3 have fully weighted hammer action?

Yes — the KeyLab 88 Mk3 uses a premium Fatar TP/110 action, which is a fully weighted hammer action with key weight graduation (heavier in the bass, lighter in the treble). This is the same Fatar action found in mid-tier digital pianos costing significantly more. For a MIDI controller, it is one of the most realistic-feeling options available.

Can I use an 88-key MIDI controller as a regular digital piano?

You can, with caveats. You will need software (a DAW, a virtual piano plugin, or an app like Apple GarageBand) to produce sound. The latency is typically very low but not zero. For serious practice and technique development, a dedicated digital piano with built-in sounds is more convenient. For producers who already have a DAW setup, a MIDI controller doubles effectively as a practice instrument.

Is the M-Audio Hammer 88 Pro a good budget MIDI controller?

Yes — it is the most affordable 88-key hammer-action MIDI controller with a built-in drum pad section, making it uniquely versatile. The key action is genuine hammer-weighted and graded, though it does not feel as refined as the Arturia Fatar action. For producers who need full 88-key range without a high budget, it is the obvious starting point.
