Midi kontroleris

Jei tingi googlinti, te:

1. MIDI, the Musical Instrument Digital Interface is a protocol developed in 1983 by major synthesizer manufacturers to allow one synth to play another remotely. They quickly found out a computer could record and playback this data and it revolutionized the way music is produced. MIDI works by sending NOTE ON and NOTE OFF events down a midi cable as well as timing information and controller (knobs, wheels, and sliders) information. IMPORTANT: Understand that MIDI does not, cannot, and will not send an audio signal. The sound of the keyboard or module does not go down the MIDI cable, only these computer encoded "events" do. This is NOT digital audio data, its MIDI data. There's more to it, but that is the basic point you have to fully understand. We'll get to digital audio later on the page. Now lets move on with understanding MIDI.

2. MIDI Sequencers (i.e., Sonar, Logic, Cubase) work by recording these NOTE ON/OFF events along a timing grid that can be played back at any tempo. When you press Play on a sequencer, it simply sends the data back to the synth, which plays it just like a player piano. Get it? Because the Synth receives the exact same events that it sent when you played the track, it sounds exactly the same. Makes sense so far? Cool.

3. MIDI instruments (i.e., keyboards and hardware sound modules) typically have 16 channels they can send and receive on. Much like your TV, you can have a different program on each channel. The only difference is that MIDI can play all 16 channels at the same time. These channels correspond to tracks in your sequencer. On each track, you can assign a different instrument. You record each track while the previous tracks play back. Because MIDI has 16 channels, you can have 16 instruments playing together, like a 16 piece band, if you want, that is totally of your own design.

4. There are 16 channels for every MIDI PORT on your computer. Your computer's soundcard are where the ports are, and when you need more you can buy a MIDI interface to add more, but to get started we'll just look at the typical soundcard so we can get you running.
