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.
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 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 port
No. Line in is for audio, but midi is for midi.
midi = noon, midday après midi = afternoon
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).
...midi files.
Recording MIDI involves using a MIDI controller (keyboard, keytar, drums, flute) in conjunction with a MIDI sequencer to create a MIDI file. This MIDI data contains all of the aspects of your performance that makes it unique (the pitch, length, velocity of the notes). Hope that helps.
Yes, as long as it has a MIDI output or USB MIDI Interface, you can use it as a controller.
A midi foot controller can be purchased online or at a specialist guitar and music store. The amplifier may need to be ordered depending on your choice of specification or even be in stock if your local music store has a good range to choose from.
