Abstract

The sound generator for an electronic organ employs a magnetic sound recording, which has a number of different recording tracks, corresponding to respective instruments or groups of instruments. The individual notes for each instrument etc. are recorded along each track and selectively reproduced via a magnetic playback head. Pref. the magnetic recording comprises an endless tape band (3) rotated via a drive shaft (1) and with 60 adjacent recording tracks corresponding to respective organ keys, scanned via a series of playback heads (5) supported by a rail (6) transverse to the tape band (3).

Description

Beschreibungdescription

Verfehren zur Ton - und Klangerzeugung bei elektronischen Olgeln Die Erfindung betrifft ein Verfahren zur Ton - und Klangerzeugung bei elektronischen Orgeln, insbesondere fOr Orgeln, welche Klangbilder der sakralen und klassischen Musik wiedergeben sollen. Der Zweck einer solchen Orgel ist es, den Klang schon vorhandener Instrumente (z.B.Procedure for tone - and sound generation with electronic Olgeln Die The invention relates to a method for generating tones and sounds in electronic systems Organs, especially for organs, which sound images of the sacred and classical Should play music. The purpose of such an organ is to make the sound already existing instruments (e.g.

Pfeifenorgel, Violine, Trompete, Flöte u.s.w.) möglichst naturgetreu nachzuahmen.Pipe organ, violin, trumpet, flute, etc.) as true to life as possible to imitate.

Bei herkömmlichen elektronischen Orgeln werden die Schallschwingungen in einem Tongenerator erzsugt. Da das Ausgangssignal des Tongenerators entweder nur Sägezahn - oder nur Rechteckschwingungen sind, müssen diese zur Erzeugung bestimmter Instrumenten - und Register klangfaroen durch elektronische Filter geleitet werden. Um aber die Klangfarben optimal zu verwirklichen maste man den Filtersufwand ins Unendliche treiben (da Ja auch die verschiedenen Tonhöhen eines Instruments oder Orgelregisters unterschiedliche Obertonstruktur aufweisen). With conventional electronic organs, the sound vibrations Generated in a tone generator. As the output of the tone generator is either are only sawtooth or only square waves, they have to generate certain Instrument and register timbres are passed through electronic filters. However, in order to optimally realize the timbres, one masters the filter effort Infinite drift (because yes also the different pitches of an instrument or Organ registers have different overtone structure).

Damit die Kosten nicht zu hoch werden, wird mit geringerem Filteraufwand nur eine rolativ unbefriedigende Nachahmung des Klangs von Orgelpfeilen und von Instrumenten erreicht. So that the costs are not too high, there is less filter effort just a relatively unsatisfactory imitation of the sound of organ arrows and of Instruments.

Da Orgelpteifon und Instrumente zueinander nicht synchronisiert sind, werden beim Klingen mehrerer Pfeilen oder Instrumente desselben Tons Schwebungen hörbar, die eine er*Onschte Belebung des Klangbilds darstellen (Choreffekt). Since the organ pipe and instruments are not synchronized with each other, beats when several arrows or instruments of the same note are played audible, which represent a real enlivenment of the sound image (chorus effect).

Bei elektronischen Orgeln der herkömmlichen Art sind Jedoch alle Tonhöhen zueinander starr fixiert, da der Oszillator meist vollständig synchronisiert ist. Das ergibt aber einen starren, und fOr den Musiker unbefriedigenden Klang der elektronischen Orgel. With electronic organs of the conventional type, however, all are Pitch is rigidly fixed to one another, as the oscillator is usually fully synchronized is. However, this results in a rigid sound that is unsatisfactory for the musician electronic organ.

Bei einer Pfeifenorgel werden die ganzzahligen FuBlagen temperiert bestimmt, die Aliquoten und Mixturen Jedoch rein. Dadurch verschmelzen diese Register besser miteinander. Da bei einer elektronischen Orgel der herkömmlichen Art dieser Unterschied im allgemeinen nicht gemacht wird, klingen Aliquot - und Mixturregistrierungen nicht sehr schön. In the case of a pipe organ, the whole-numbered feet are tempered Definitely, the aliquots and mixtures, however, pure. This will merge these Register better with each other. Since with an electronic organ the conventional Kind of this distinction is not made in general, sound aliquot - and Mixture registrations not very nice.

Ebenfalls wird bei herkömmlichen elektronischen Orgeln das Rauschen der Pfeilen (unharmonische Teiltöne) nicht erzeugt. Also with conventional electronic organs, the noise becomes the arrows (inharmonic partials) are not generated.

Um die obengenannten Nachteile der elektronischen Orgeln zu beseitigen wird der Ton und Klang Jeder einzelnen Pfeife oder Jeder einzelne Ton und Klang eines bestimmten Instruments, odor auch ganze Klangkombinationen vorab in der Orgel gespeichert und auf Abruf bereitgestellt. To eliminate the above-mentioned disadvantages of the electronic organs becomes the tone and sound of every single whistle or every single tone and sound of a certain instrument, or even whole sound combinations in advance in the organ stored and made available on demand.

Dies geschieht gemäß der Erfindung dadurch, daß ein magnetisierbarer Tonträger (z.B. Tonbandmaterial) mit Tonspuren versehen wird, die bei Rotation des Tonträgers in sich zurücklaufen (z.B. Endlosband), daß ferner Jeder Einzelton einer Pfeife, eines Instruments, einer Klangkombination, eines Orchesters, eines Chors u.s.w. auf eine Spur aufgenommen wird, und daß durch Abspielen Ober Magnettonköpfe die gespeicherten Töne wieder zur Verfugung stehen. This is done according to the invention in that a magnetizable Sound carrier (e.g. tape material) is provided with sound tracks that are released when the Sound carrier run back in itself (e.g. endless tape), that furthermore every single tone is a Whistle, an instrument, a sound combination, an orchestra, a choir etc. is recorded on a track, and that by playing over magnetic sound heads the stored tones are available again.

Die mit der Erfindung erzielbaren Vorteile sind im folgenden autgazähit. The advantages that can be achieved with the invention are described below.

Der Klang von Pfeißen und Instrumenten u.s.w. ist vollständig nachgeahmt, ebenso deren Vielchörigkeit. Die bisher möglichen weiteren Ein. The sound of pikes and instruments etc. is completely mimicked, likewise their polychoirism. The other possible ones so far.

flußnahmen der Elektronik auf den Klang (Hüllkurven, Effekte, Hall u.s.w.) und die Möglichkeiten der Schaltungstechnik (Koppeln, Kombinationen, Mehrkanalige Verstärkung u. s.w.) bleiben erhalten. Es ist z.B. möglich, auf denselben Tonträger, auf dem die Töne eines einzigen Registers Platz hAtten auch die Töne des Vollen Werks einer hundertregistrigen Pfeifenorgel aufzun@hman (oder das Tutti eines Orchesters u.s.w.).the effects of electronics on the sound (envelopes, effects, reverb etc.) and the possibilities of circuit technology (coupling, combinations, multi-channel Reinforcement and so on) are retained. It is e.g. possible to use the same sound carrier, in which the notes of a single register would also have room for the notes of the full Work of a hundred-register pipe organ (or the tutti of an orchestra etc.).

Es können außer Orgel -, Orchester - und Soloinstrumentenklänge auch Summchöre, synthetische Klängs u. dgl. auf die Tonträger aufgenommen werden. Es uB sich nur grundsätzlich um Dauertöns handeln. In addition to organ, orchestral and solo instrument sounds, it can also be used Humming choirs, synthetic sounds and the like can be recorded on the sound carrier. It can only basically be continuous tones.

Im folgenden ist eines von verschiedenen möglichen Ausführungsbeispielen erläutert. Das Ausführungsbeispiel stellt ein Dauertonverfahren dar. Es zeig@n: Fig. 1 die Draufsicht Fig. 2 den 8chnitt A - B Du Endlosband 3 wird zwischen der Antriebswelle 1 und der Andruckwelle 2 bei Rotation der Antriebswelle 1 stetig hindurchgetrieben; es läuft Ober die Haltewelle 4 wieder zurück. Das Endlosband, das vorab mit 60 Tonspuren bespielt worden ist (entsprechend 60 Tasten) kann nun Aber eine Reihe von Magnettonköpfen , die auf der Leiste 6 betestigt sind, abgehört werden. Der Tonkopf 5 stellt einem von 15 Vierspurtonköpfen dar, Die Leiste 7 trägt einen Filzstreifen 8 , welcher den Andruck des Magnetbandes an die Tonköpfe besorgt Die Schaltung der Einzeltöne kann direkt über Tastenkontakte oder über Hüllkurvenschaltungen wie bisher üblich erfolgen. The following is one of several possible embodiments explained. The exemplary embodiment represents a continuous tone method. It shows @ n: Fig. 1 is the top view Drive shaft 1 and the pressure shaft 2 when the drive shaft rotates 1 steadily driven through; it runs back over the holding shaft 4. The endless belt that has been recorded with 60 audio tracks beforehand (corresponding to 60 keys) can now But a number of magnetic sound heads, which are fixed on the bar 6, bugged will. The sound head 5 represents one of 15 four-track sound heads, the bar 7 carries a felt strip 8, which takes care of the pressure of the magnetic tape on the tape heads The switching of the individual tones can be done directly via key contacts or via envelope circuits take place as usual.
