No—but it helps a lot. You can click in notes with a mouse, but a MIDI controller makes the process faster, more intuitive and expressive. It’s especially useful for playing chords, recording performances or automating effects live.

It depends on your space and goals. A 25-key controller is great for portability and simple parts. A 49- or 61-key layout gives you more range for two-handed playing or full performances. Most beginners start with 49 keys, but you can go bigger or smaller depending on how you plan to use it.

Pros: A MIDI controller gives you hands-on control over your digital instruments, making your workflow more musical and expressive. They're compact, affordable and often come bundled with great software, such as Ableton Live Lite or MPC Beats. You can customize layouts, assign functions and even take them on the road with ease.

Cons: Unlike a traditional keyboard or synth, MIDI controllers don’t make sound on their own—they rely on being connected to a computer or external module. Some entry-level models may lack features like aftertouch or dedicated transport controls. Also, DAW integration can vary depending on the model and software.
