MIDI-sequencers from the hurdy-gurdy to the "PSR-ki" first sequencers can be called, perhaps, the ancient street organs, because they had implemented the basic principle of modern music programs: once recorded or "manufactured" a melody with accompaniment – a lot of time to reproduce. Why suffer, to learn musical notation, for hours to hone performance skills, where you can buy ready-made box with a set of hits and just a crank? Maybe Papa Carlo in his youth arranged worldwide concert tour and collecting stadiums – the primary sources of this silent In any case, it is clear that the demand for such products did not appear yesterday, means, and will last long. In the 70 years of the twentieth century sequencer became known as a synthesizer, which can be programmed sequence of several notes. Most often they were different versions of decomposed arpeggios. The musician took on such a keyboard chord and began sequencing "Rinse" it across the range.
Sometimes the musicians managed to synchronize the pace of these broken lines with arpeggios tempo play. A little later in odnogolosy analog synthesizers became possible to program small (one or two cycles) melodic pattern. Usually it is used to create a bass solo or party and is repeated as many times as lacking "chutzpah" in the arranger. Managing the various regulators and switches, the musician could in real time to influence the tone and image sequence and, thus, to approach "audio calculator" in terms of expressiveness to "live" instruments. Discreet Charm of MIDI-technology Formed in the early 80's new music-electronic technology (MIDI) gave a composer and arranger few important things: write the party not only by programming them, but also performing "live"; write long and complex sequences of notes, written polyphony; play multiple parties with different timbres, make a few synthesizers work well, different in nature and created by different manufacturers. To this end, MIDI-technology has introduced several new concepts for the music – MIDI-channel, MIDI-controller, SysEx-mails, and more.
