    To simplify playing of an electronic instrument and to avoid the otherwise clearly recognizable synthetic sound quality, the operating elements are arranged in a wind or blowing body constructed and playable similar to a mouth-harmonica. These operating elements comprise a pressure sensor responsive to the blowing and suction air current or stream of a human being and which is coupled to a mouthpiece displaceable along the wind or blowing body, and a number of position sensors which respond in accordance with the momentary position of the mouthpiece. The pressure sensor and the position sensors are coupled to an evaluation circuit which is structured such that it generates, as a function of the response of these sensors, the control voltages required for controlling the synthesizer.

In the absence of air flow in the pipeline 37, the output signal of the converter 5 corresponds to the voltage on the bus 43.

    The frequency control bus connects the bias source bus 11, the voltage of which is chosen so that the output voltage of the channel 9 increases by an amount corresponding to 1/2 tone dp of the synthesizer 16.
    Potentiometer 14 serves to obtain the effects of vibrato, glissando, and the like. by supplying a variable voltage to the second input of the adder 12. The organs 42 of the adder 12 allow its input signals to be supplied not only to the corresponding, but also to the adjacent outputs. Thus, a specific type of modulation of sound by a potentiometer 14 is determined by the installation of organs 42.
    The generation of frequency and amplitude control signals in channels 9 is as follows.
    The output signal (voltage) from the output 8 of the generator 7 is fed to the input 22 of the A / D converter 17, at one of the outputs of which a digital signal arises. This signal is converted by the encoder 18 into a binary code, which through the switch enters the control inputs of the PDP 20. At the output of the DAC 20, a constant voltage is generated. scaled according to the characteristic of the D / A converter 20, and the voltage of the source 25 for matching with the synthesizer 16. The output voltage of the D / A converter 20 is added to the summing amplifier 21 with the voltage on the bus 11 to obtain a shift of 1/2 tone. At the output of amplifier 21, a sound frequency control signal is directly generated.
    The additional input 23 of the encoder 18 serves to control the tones, p. radiated in one position of the mouthpiece 3 when blowing and sucking air.
    In channel 15, the output signal of converter 5 is brought to zero with a differential amplifier 26, the input 34 of which is under-. Connected to the bus 35 of the bias source, the voltage of which is equal to the voltage on the bus 43 in the housing 1. Thus, increasing or decreasing the pressure in the pipeline 37 leads to a change in the polarity of the output voltage of the amplifier 26. This voltage is applied to the inputs of the detector 30 field Ratio (comparator) with a full-wave rectifier 27.
    The output signal of the detector 30 is fed to the auxiliary input of the encoder 18 and serves to distinguish the currents extracted in one position of the mouthpiece 3 when blowing or sucking air according to Fig.4.
    The signal from the output 28 of the rectifier 27 is fed to the third input of the adder 12 to control the amplitude of the extracted sound, as well as to the input of the threshold detector 29, the output signal of the detector 29 allows the binary code to pass through the switch 19 from the encoder 18 to the ADC 17. The signal A solution appears at the output 32 of the detector 29 only if the voltage at the output 28 of the rectifier 27 exceeds a certain specified value determined by the bus voltage 36. If the voltage at the output 28 is less than this value, the switch 19 closes and control signal No frequency is formed. Thus, there is a certain threshold level of the velocity head of the air flow in the mouthpiece 3 in one direction or another, below which the pressure is not recorded. This prevents the extraction of sounds when accidentally blowing
    or air in the mouthpiece 3.
    Thus, at the outputs of the adder 12, three voltage signals are generated to control the frequency, timbre and amplitude of the synthesis sound -. Torah 16.
    Using the proposed control device, it is possible to play four octaves, indicated in Figures 4 through I through IV. In addition, with the help of a control device, you can play an electronic musical instrument without any difficulty while familiarizing yourself with playing the harmonica.
    The ability to control the signals determining the pitch, timbre and amplitude of the extracted sound in a wide range of their values, as well as controlling the law of variation of these signals in accordance with the individual musician's technique, expands the performance capabilities of the proposed device compared to the known, and also increases the quality of the extracted sound.
