Description
Technical field
The present invention relates generally to music technology.More particularly, the present invention provides a kind of method and system that is used for networkings such as musical instruments.But it should be understood that the present invention can have range of application widely.
Background technology
MIDI (musical instrument digital interface, the International Phonetic Symbols :/midi/) be a kind ofly make that electronic musical instrument, computing machine and other equipment can be communicated by letter, control and industry-standard protocol synchronized with each other.MIDI allows computing machine, compositor, MIDI controller, sound card, sampling thief and electronic drum to control each other, and exchange system data (as the raw data method for packing that is used for the SysEx order).
As a kind of electronic protocol, it should be noted that it is adopted widely in whole industry, and it is using always after being introduced into from nineteen eighty-three.Now, most popular recording music is through using the electronic keyboard (being also referred to as " compositor ") that is equipped with MIDI to write down and play.Many music also are through using " SEQ sequencer " and/or " DAB workstation " record on computers.Also can use other to be equipped with the musical instrument of MIDI, comprise digital drum, digital guitar and wind instrument etc.
Most computing machines can use the built in hardware or the software compositor of response MIDI message to play the MIDI file; And through suitable adapter; Your computing machine can be connected to other product that is equipped with MIDI, so that you can use MIDI to help your study, performance, creation and music appreciating.
Even if dubbing in background music of film and TV also created on the MIDI instrument usually; And along with the development on digital sample and synthetic technology; It is more true to nature to make digital music instruments sound; It more likely is the product of several MIDI equipment that orchestral music behind the screen sheet is played, and irrelevant with a large amount of acoustic instruments.
Yet although past music making and sound design more to be depended on the minimum electronics of acoustic instrument and chorus-in the operating room, need and is connected-, the surge of MIDI and computing machine needs are increasing in the manufacturing process directly be connected to come data signal.Multi-linkly more mean many more cable lines usually.
Yet MIDI limits to some extent.Promptly; MIDI is not transmitting audio signal or medium-its transmission " event information "; Such as, treat notes pitch and intensity, parameter control signal (such as, volume, trill and left and right acoustic channels), index file (cue) and the clock signal that is used to be provided with beat.The common issue with of commercial, specialty, semi-professional project work chamber and family operating room etc. is the overwhelming clutter echo relevant with stube cable, especially when some equipment from convenient, logistics and common space management purpose and need for any kind perhaps with its signal point of destination (or receiver) any apart apart from the time.
The cable that these cables comprise various voice-frequency cables, power cable and are used for MIDI (musical instrument digital interface) controller and instrument are connected to sound module and/or computing machine.Some controller (such as, MIDI frame drum) or to be equipped with the grand piano of MIDI huge and heavy does not have portability, this big limitations the option of mechanism.
According to above-mentioned, visible ten minutes need be used to improve the technology of MIDI and musical instrument use.
