MIDInäppäinohjain

MIDInäppäinohjain, often called a MIDI keyboard controller, is a musical input device that uses the MIDI (Musical Instrument Digital Interface) protocol to send performance data to a computer or other electronic musical instrument. It does not produce sound itself but rather acts as an interface to control virtual instruments or hardware synthesizers. The most common form factor resembles a traditional piano keyboard, with velocity-sensitive keys that can detect how hard or soft they are played.

Beyond the keys, MIDInäppäinohjaimet typically feature additional controllers such as pitch bend and modulation wheels, assignable knobs, sliders, and drum pads. These controls allow musicians to shape the sound of their instruments in real-time, adding expression and nuance to their performances. The data sent via MIDI can include note on/off messages, velocity, pitch bend, controller changes, and program changes.

MIDInäppäinohjaimet come in various sizes, from compact 25-key models suitable for mobile setups to full 88-key instruments mimicking the range of a piano. They connect to computers via USB or sometimes older MIDI DIN connectors. Software is essential for a MIDInäppäinohjain to function, as it translates the incoming MIDI data into audible sound through digital audio workstations (DAWs) or standalone virtual instruments. They are indispensable tools for music production, live performance, and sound design.
