Description
The invention belongs to electronic musical instrument.
In existing electric keyboard instrument, have have three kinds of regimen modulation function.A kind of is Japanese " pure temperament electronic keyboard musical instrument " (special be willing to clear 57-2185 number), and it can the regimen modulation, but the modulation error is very big, is 445.5Hz as the A sound of the big accent of D among its 3rd figure; The keynote A of the big accent of A is 440Hz, and turning greatly from D must downward 5.5Hz out of tune to the big timing of A, exceeds admissible scope.The G sound of d ditty is 391.1Hz among its 4th figure, and the keynote G of g ditty is 396Hz, and the 4.9Hz out of tune that must make progress when the d ditty turns to the g ditty also exceeds the scope of permission, or the like.Second kind is Chinese " keyboard type electronic organ with adjustable melody and tone " (application number is 86 2 09305), it in Table 1 the A of c major be 436.535Hz; It is added, and " the master sound of each scale all just is placed on and restrains." A that just restraining in the table one is 440Hz.If when c major turns to a ditty, the 3.465Hz out of tune that must make progress exceeds the scope of permission.And it all has same error in the mutual commentaries on classics of 12 pairs of large and small accent of relation.The third is that the inventor designs " three temperament electronic musical instrument " (application number is 87 2 15053.4), and it has adopted 53 rules of " room, microphony difference capital rule ", and each differs from 24 accent of 22 cents to have used two rows accent of the same name, solves the modulation problem of 12 accent.The pitch that this transfers keynote is calculated in each modulation earlier, calculates the pitch of other each sound again according to the altitude gauge of keynote.With this two-stage Calculation Method, only solved and gone to change the error that must occur in 12 accent with 12 accent.Although can carry out the regimen modulation in above-mentioned several Electronic Keying disc type musical instrument, and the error latter of modulation solves.But, manual type is all adopted in modulation, each modulation needs with manually clicking manual modulation key/turn round, and the player also must be when playing, note constantly going to analyze turning to certain accent by certain, both bring the many troubles that do not have in the former keyboard instrument use, increased player's mental burden again.
Task of the present invention is: on the three temperament electronic musical instrument that can show three kinds of basic musical notes such as pure rule, five tone cadence temperament and twelve-tone equal temperament, provide a kind of autocontrolled modnlation device; Utilize the normal running method of keyboard instrument, finish the autocontrolled modnlation task.
Realize that basic thought of the present invention is: utilize player's employed that a part of key when playing, with these keys as signal, with designed autocontrolled modnlation device signal is analyzed, what judge performance is what is transferred, and then finishes automatic modulation task according to the result who analyzes by the autocontrolled modnlation device.
Big accent in the music has 12; Ditty divides three kinds: antural minor, harmonic minor and melodic minor, totally 36 accent.With c major and concern that ditty a ditty is an example, be listed as follows:
C major: c d e f g a b
Nature a ditty: a b c d e f g
Harmony a ditty: a b c d e f
*g
Melody a ditty is up: a b c d e
*f
*g
Melody a ditty is descending: a b c d e f g
Autocontrolled modnlation needs certain device to realize, but finishing of this Design of device and task must be based on the basic theories of music.Play the analysis with " accent ", its signal derives from black, Bai Jian operated when playing, and the door of setting the tone really the soonest must make the bond number of analysis fewer better.It is considered herein that, in performance behind specific five sounds of minimum appearance, just can distinguish it and be 12 groups and concern which group in the large and small accent.These five sounds are: one-level sound, three grades of sounds, level Four sound, Pyatyi sound and seven grades of sounds on big tuning rank; The secondary sound of minor scale, three grades of sounds, Pyatyi sound, six grades of sounds and seven grades of sounds.Big secondary pitch 22 cents of transferring in pure rule, the level Four sound of ditty hang down 22 cents, clear what play is big accent or ditty so also must further distinguish.But when antural minor and melodic minor were descending, used sound and the big accent of its relation together, can't be distinguished with the situation of key entirely, so the present invention uses big chord with big the accent again, ditty is used the method for little chord, and adjacent sound and the chord used always before and after playing with it are done to distinguish for the second time.Because of its secondary sound and Pyatyi sound in big accent the, seven grades of sounds constitute a Major chord; Its level Four sound and six grades of sounds, one-level sounds constitute a minor triad in ditty.Must be big accent so after Pyatyi sound and seven grades of sounds occur, occur the secondary sound again; After six grades of sounds and the appearance of one-level sound, occur the level Four sound again and must be ditty.The former is with secondary sound 22 cents that raise; The latter reduces by 22 cents with the level Four sound, and its scale promptly meets each required pitch in large and small tuning rank fully.
Autocontrolled modnlation device of the present invention is divided into secondary, and the first order is be " the natural law autocontrolled modnlation device " that is used for screening pitch, and it is made up of code translator, latch and proprietary program, or is made up of single-chip microcomputer (or single card microcomputer) and proprietary program.The second level be the device that is used for screening tonality " pure rule automatic control interval regulating device ", it is made up of code translator, latch and proprietary program, also can form with single-chip microcomputer or single card microcomputer, input circuit and proprietary program.Outside the needs of division tonality of the present invention, also there are a kind of inconsonant " narrow five degree of pure rule " in pure rule itself, also needs to be adjusted into consonance, so, " pure rule automatic control interval regulating device " distinguished the tonality task except that bearing, and adjusts the task of cacophony journey in addition.In the general performance of not modulation, " pure rule automatic control interval regulating device " is in order to carry out the task of the cacophony journey of adjusting pure rule and musical note among the people.Its control method also is by deciding for Major chord or minor triad of being played, and is identical during with modulation.After originally " natural law autocontrolled modnlation device " filters out the used pitch of performance, signal is sent into the program of aforementioned " three temperament electronic musical instrument " of inventor's design, again through selecting the frequency of the first sound of new key, and after selecting the calculating of other each voice frequency twice formula, select 12 used sounds of new accent, transfer to keyboard, its modulation is stable, and frequency is accurate.
In addition; because the musical note among the people of various countries has multiple scale in same pitch, adjacently respectively transfer regular meeting to mix to refute, can not why it transfers with the methods analyst of collecting the white-black key signal; so also must preserve original 12 manual modulation keys, use when playing musical note among the people.
Using method of the present invention is: set up the rule classification key of five interlockings, it is in proper order: 1 is pure rule key, and 2 is joyous key among the people, and 3 is bitter key among the people, and 4 is the five tone cadence temperament key, and 5 is the twelve-tone equal temperament key.Press the frequency that different keys can send different musical notes.Also having established an autocontrolled modnlation key and 12 manual modulation keys of interlocking in addition, still is that manual control can be chosen wantonly with automatic control.Manual modulation key is chequered with black and white, and shape is with key, large and small blending one key of the same name, also be provided with a pure rule automatic control interval adjusting key, press this key and can regulate the cacophony journey of pure rule and musical note among the people automatically, not according to this key, performance then be each standard scale of transferring of each rule.
