25-Note MIDI Keyboards

Yes, 25 keys can be sufficient for many music production tasks, such as creating bass lines, leads, and simple chords. They are especially useful for mobile setups and live performances where space and portability are critical. However, for more complex compositions that require a wider range, additional keys may be needed. 

Important features to consider include velocity-sensitive keys for expressive playing, assignable knobs and faders for controlling software parameters, and drum pads for beat-making. Additionally, look for good DAW integration, portability, and connectivity options such as USB and MIDI out. 

25-key MIDI keyboards are highly portable due to their compact size and lightweight design, making them ideal for on-the-go music production. Durability varies by model, so it's advisable to choose one with a solid build quality, reinforced keys, and reliable construction materials to withstand frequent travel and use.
