The MIDI (Musical Instrument Digital Interface) system has nothing to do with the range of frequencies.
MIDI is a method of communicating between various musical controllers, such as keyboards, and generators, such as synthesizers. The synthesizer is what actually generates the frequency. The MIDI system is simply the messaging subsystem. Think of it this way - one parallel to MIDI is a player piano roll.
The MIDI system itself does not produce sound or frequencies. MIDI is a communication protocol used to trigger and control electronic musical instruments, including synthesizers and samplers. The range of frequencies produced by a MIDI-based setup depends on the capabilities of the connected sound-generating devices rather than the MIDI protocol itself.
i doesn't have the widest range the synthesiser does
The MIDI (Musical Instrument Digital Interface) system does not care about the range of frequency of the actual instrument it is playing. It is an event oriented system, much like a player piano, not like a tape recorder, so what is recorded are key down and key up (and other) events, rather than musical waveform events.
A MIDI keyboard can produce a wide range of sounds, including piano, strings, drums, synthesizers, and many more.
A sound card can have both MIDI inputs and outputs. The outputs are used to control an external device, to provide a wider range of sound than is possible with the built-in wave table.

midi = noon, midday après midi = afternoon
No. Line in is for audio, but midi is for midi.
The sound can be fed into software that will analyze the frequencies and peaks of the music, and generate a real-time 'visualization' of the music.
A MIDI controller sends MIDI note messages to another device by MIDI cables or USB to a computer. If it is strictly a MIDI controller with no onboard sounds, it will have to connect to another MIDI device or computer to make sounds.
A Ensoniq KS-32 can be used as a MIDI controller. If you are using an audio interface that has MIDI ports, connect the MIDI Out of the Ensoniq to the Interface's MIDI In. If you don't have a MIDI port on your interface (such as with the Mbox Mini) you will have to buy a USB MIDI interface (they're about $40.00).
