Definitions

  • the invention relates to a metronome with optical and / or acoustic rhythm reproduction at an adjustable beat frequency, an input device being provided for inputting a sequence of note 'or pause values forming at least one cycle duration, furthermore a memory for the input sequence, a circuit for repeatable generation control signals corresponding to the input sequence taking into account the set beat frequency and at least one optical output device responsive to these control signals, according to the preamble of patent claim 1.
  • Metronomes of the known type have the disadvantage, which is particularly important for people who are less well-versed in music, that they are pure strikers which, regardless of the time signature and rhythm, deliver uniform signals.
  • the metronome according to the invention has the advantage of an easily understandable, geometric assignment of the fixedly arranged display elements to the cycle, without using additional, distracting information outputs.
  • the start of the bar which is a striking reference point for the player, can be clearly recognized by the assignment to the first display element in the row.
  • the metronome has an optical output device according to claims 2 or 3. It is thus possible in a simple manner to implement the chronological sequence of relatively small note or pause values in a spatial sequence over an entire cycle duration, which improves the clarity of the sequence and thus the Learnability is further facilitated, and greater precision is made possible in understanding the rhythm.
  • the memory provided according to claim 1 for the entered sequence of note or pause values has a capacity to accommodate a sequence comprising several clock periods. This has among other things the advantage that time changes can also be represented and the rhythm of longer musical themes can be generated.
  • Fig. 1 an embodiment is shown in front view, as the user has in front of him.
  • the metronome is located in a housing 1, which has a relatively low height, so that it can be arranged under the sheet of music on a music stand.
  • a holding strap 2 or other suitable means, such as clips, can be used to attach it to the music stand.
  • the metronome is advantageously arranged in such a way that both the note image and the front plate 3 of the metronome can be grasped at a glance.
  • the most important operating and display elements are arranged on the front panel 3.
  • a keypad 4 is used to enter the sequence of note or pause values to be reproduced.
  • the input process is as follows: after switching on the device by means of a switch 5 and pressing a reset button 22, the rhythm to be played is typed in by successive actuation of the correspondingly labeled touch buttons 6 or pause buttons 7. Dotted notes are entered by pressing a puncture key 8 after pressing the corresponding key 6.
  • a triplet key 9 is provided for the input of triplet figures, which is actuated before the input of three note values which represent the triplet in the note image becomes.
  • the measure end key 10 is actuated, which in the optical display, as will be explained in detail below, causes a reset to the beginning.
  • note or pause values up to the note total 1 can be entered within one bar, ie up to 16 sixteenth notes or two quarter notes and eight sixteenth notes etc. per bar.
  • note or pause values can also be entered to represent a 3 ⁇ 4 measure, which together make up less than the value 1.
  • the most important time signatures can thus be set.
  • up to 8 cycles can be typed in contiguously, and cycle changes, for example from% cycle to 1/4 cycle and back, are also easily possible.
  • the entered sequence is then reproduced repeatedly at a specific beat frequency set by means of a three-decimal switch 12.
  • An optical and an acoustic output device are used for signaling and are described in detail below.
  • the optical output device 13 consists of a series of optical display elements, for example formed by a row of light-emitting diodes 14, which is divided into groups of four. A total of four groups of four are planned. '
  • the visual representation is now carried out in such a way that, while maintaining the set beat frequency, the note values within the bar are assigned a number of light-emitting diodes corresponding to their position in the bar and their value.
  • the note values are displayed in that the corresponding light-emitting diodes light up successively in the frequency of the smallest representable note value, and remain in this state until the note duration has expired.
  • the actuated LEDs go out at the same time.
  • the z. B third quarter note represented by successive lighting of the LEDs 14 of the third group in the rhythm of the sixteenth notes.
  • the quarter note expires, the whole group goes out at the same time.
  • each diode lights up only for the duration of a sixteenth note and then immediately extinguishes again.
  • the entire row 13 of the optical display elements is not run through, and the display is reset to the beginning after one cycle time.
  • the last group of four of the display elements 14 therefore remains unused.
  • Breaks are displayed by skipping a corresponding number of display elements, with no element lighting up during the duration of the break.
  • the display elements corresponding to the pauses light up dimly or that elements of different colors are provided for this.
  • FIG. 2 shows a further possible optical output device which is operated essentially the same as that explained above, but the individual note values can also be represented as such.
  • the note values drawn in FIG. 2 are to be understood as electrode arrangements for a liquid crystal display, which become visible only when actuated and are otherwise imperceptible.
  • the bottom row of electrodes 15 is used to represent sixteenth notes and triplets. This row is operated like row 13 of the display elements in FIG. 1, which is why a further explanation is omitted.
  • the corresponding note value is now visible throughout its duration in one of the upper rows 16 to 19. So z. B.
  • This arrangement has the advantage, especially for beginners, that the display largely matches the note image with regard to note values.
  • an acoustic output device which can be set or switched off to the desired volume by means of an actuating button 20 (FIG. 1) is cash.
  • the acoustic output device has a loudspeaker, which is preferably arranged on the bottom or top of the housing 1 (not shown) and which generates a tone of a specific frequency, preferably 440 Hz, so that the instruments can then be tuned at the same time. Its duration depends on the note value to be displayed, but is shortened by a fixed amount of time so that successive notes can be distinguished without a break.
  • an external output can be provided at which, for. B. a headphone or a tape can be connected.
  • the acoustic output device can first be used together with the optical output device until the rhythm is learned. After that, the optical display can be used alone and ensure accurate reproduction.
  • the metronome also has a decade, three-digit clock counter display 21 on its front plate 3.
  • the number of cycles played is displayed.
  • This allows you to keep longer pauses in an instrument without tedious counting, but on the other hand you can easily number musical notes that do not yet have a bar number.
  • the measure counter is reset to 0 each time a reset button 22 «Reset» is pressed.
  • an external connection 23 is arranged on the front plate 3, by means of which several metronomes of the type shown can be electrically connected to one another. This makes it possible to start several metronomes at the same time, so that several synchronous metronomes can be used in an ensemble, which further increases the effectiveness of the optical output device compared to conventional optical metronomes.
  • the keypad 4 is connected to a first input unit 24. Furthermore, the decimal switch 12 is connected to a second input unit 25. These input units are connected by means of an 8-bit data bus 26 to a microprocessor and memory 27 for the input note sequence.
  • the microporcessor 27 has a quartz oscillator 28 which oscillates at a frequency of 4 MHz.
  • the microprocessor 27 is connected via an 11-bit address bus 29 to a read-only memory 30, in which an operating program is permanently stored.
  • the read-only memory 30 is in turn connected to the 8-bit data bus 26, which leads to an output unit 31.
  • the optical output device 13 with a plurality of light-emitting diodes, a clock counter 32 with the clock counter display 21 and an oscillator 33 with loudspeaker 34 for acoustic signaling are connected to the latter.
  • the first input unit 24 has a 2 ⁇ 8-bit input register 50, via which the commands entered by means of the keypad 4, which contains the keys shown in FIG. 1 (without the reset key 22), on the 8-bit Data bus.
  • the second input unit 25 has an 8-bit input register 36, to which a BCD switch 25a, 25b is connected for the tens and one input of the time measure.
  • the hundred units are entered via a BCD switch 25c, which is part of the first input unit 24 and can be set to the values 0.1 or 2.
  • the microprocessor 27 to which the input commands arrive, processes 8-bit words with a cycle time of 1 ps and has a read / write memory with a capacity of 128 bytes, in which these notes are stored. As mentioned, this allows the entry of a sequence of 8 measures.
  • the operating clock of the device as well as the beat frequency and the note durations are derived from the 4 MHz clock oscillator 28.
  • the reset button 22 is connected to a reset input 35 via a circuit 37 for eliminating switch bounce effects, which also has the external reset connection 23.
  • a clock counter reset circuit 38 is provided, which is also connected to the reset input 35 of the microprocessor 27.
  • the microprocessor 27 is connected via an 11-bit address bus to a read-only memory 30 which has a capacity of 2048 8-bit words.
  • the read-only memory contains the program for the functional sequences explained. It is not shown here again because this program is within the range of the skilled person due to the described mode of operation of the metronome and is not the subject of the invention.
  • the output unit 31 has a 2 x 8-bit output register 39 and two 8-bit buffer registers 40, each of which is connected to 8 LEDs 14.
  • the output unit 31 is also connected to the clock counter 32, which is BCD-coded.
  • the clock counter is connected to a display multiplex unit 41 and a BCD-7 segment converter 42, by means of which the clock counter display 21 is operated.
  • the clock counter can be set to zero by means of the clock counter reset circuit 38.
  • the output register 39 also has the 440 Hz oscillator 33 with loudspeaker 34 at an output.
  • a power supply unit provides the necessary supply voltages.
  • a rechargeable battery can also be provided for this.
  • the device described has the advantage that any rhythm can be generated within the framework of the typable note or pause values, it being possible to achieve a signal which represents the passage of time with the optical output device.
  • This allows the rhythm to be reproduced precisely even after the initially useful acoustic signaling, which later becomes disruptive when making music, is switched off, since not only the length of time that has already elapsed, but also the one that is still to come, is visible, especially with longer note values.
  • this not only clearly defines the start of a note value, but also the end of it.
