Definitions
- the invention relates to an arrangement for pressure point generation in keyboards for piano-like electronic keyboard instruments, in particular in keyboards for electronic harpsichords and electronic organs with which the Operation of key levers sensors are controlled and in which the Generation of pressure points key lever with a scanner, consisting of a sensor and a key magnet, are connected.
- EP 0 567 024 B1 discloses a device in which two Permanent magnets are arranged homopolar to each other, so that the Overcoming the repulsive magnetic field is perceived as a pressure point, when the magnets are passed each other.
- US 5 922 983 replicates force-relevant mechanical processes a piano or piano keyboard described by pressing the keys by a processor using predetermined curves that of a key sensor detected key movement data one of the key associated solenoid controls.
- this device allows the Imitating the feel of a simulated piano beat, it enables but not the significantly different touch feel of a pipe organ manual or that to reproduce a polychoral harpsichord.
- Instrument types can not be simulated by a single device become.
- a typical piano attack type in which one slowly pressed first Button is finally accelerated to a still relatively loud tone can not be replicated with these keyboards. It would be also desirable to be able to simulate the pressure point as it the Tastmerkmalen the opening and closing of the shutter valve a Pipe organ comes as close as possible. It should be analogous to the operation of the Pipe organ the increase of the pressure point strength with the addition of several Organ register can be felt, the pressure point occurs relatively spontaneously. Likewise, the simulation of stringing the strings in a polychoral Harpsichord can be palpated.
- the invention is based on the object, an arrangement of the above specify the type mentioned, with the pressure point behavior are simulated can, both a cembalotypic attack type and the Tastmekmalen an organ comes as close as possible and also one dynamic stop as well as several pressure points during one To simulate key operation allows.
- the object is achieved with an arrangement that the in Having claim 1 features.
- the arrangement according to the invention makes it possible with a comparatively simple circuit arrangement to simulate diverse varieties. It is particularly advantageous that multiple pressure points in strength, position and Length are electrically adjustable. It is possible, the pressure point impulsive with steep or with a rise to be generated by a any curve is formed. There are different parameters for this Press and release the button selectable. Furthermore, it is possible that the Keyboard to be assigned to different tone generators.
- FIG. 1 explains the mode of operation of the arrangement.
- Each key lever 1 is associated with a sensor 3, the frame fixed on a support plate 3.1 is.
- An integral with the key lever 1 plunger 1.4 transmits the Button movement on the ring magnet 4.
- the key stroke is with the Stop felt 1.2 limited.
- the position data of the button lever 1 become by signals which the sensor 3 during the passage of the ring magnet 4, transmitted to an analog signal conditioning unit. in the this example is a comparator unit 5, but it is also possible that as an analog signal conditioning unit, an analog-to-digital converter is used.
- the analog signal conditioning unit is a programmable evaluation unit 6 downstream, which the data for externally connected digital signal processors 7 generated.
- the key lever 1 is coupled to the armature of an electromagnet 2.
- the electromagnet 2 is from the evaluation unit 6 after evaluation of the position data and in Dependence on a current programming via the magnetic driver 13 driven.
- the external digital signal processors (DSP) 7 are with the programmable evaluation unit 6 connected.
- This is DSPO a sound expander for organ, DSPL a sound expander for harpsichord and DSPDYN a sound expander for dynamic attack, for example a piano expander.
- the target voltage unit 8 controls in conjunction with the data field 9, the comparator 5.
- the data field 9 is a external computer 10 connected to the data determination.
- An internal calculator 11 receives data from the data memory 12, the digital-to-analog converter 15th be supplied.
- the magnetic driver 13 is used both by the Voltage regulator unit 14 as well as from the programmable evaluation unit 6 controlled.
- Figure 2 shows in the phases a) to f) steps of the movement sequence in the operation of the button lever 1.
- the key lever 1 is mounted in the pivot bearing 1.1 and is held by weights, not shown springs in the rest position shown in position a).
- the key stroke in the direction of the arrow is limited by the stop felt 1.2.
- the electromagnet 2 with bobbin 2.1 and rod anchor 2.2 is positioned near a contact surface 1.3 below the button. About the contact surface 1.3, the connection between the button and bar anchor 2.2 is made.
- the contact surface 1.3 is advantageously designed as a screw.
- Firmly connected to the keyboard frame is designed as a printed circuit board carrier plate 3.1 with the sensor 3.
- a permanent magnet is shown in the form of a ring, whose axis is connected to the keyboard frame.
- the ring magnet 4 has two oppositely magnetized semicircular segments. In the illustrated position, the north pole of the magnet is directed toward the sensor 3. In this case, a maximum voltage is generated at the sensor 3 in one of its two possible current directions.
- the ring magnet 4 is rotatably mounted on the frame and is, as shown in b), rotated upon depression of the button lever 1 by the plunger 1.4 about its axis, whereby the effect of the magnetic field on the sensor 3 attenuates and thereby changes its voltage. In this position, the solenoid 2 is turned on and pushes its rod anchor 2.1 from below against the key lever 1.
- the sensor 3 is directly followed by a processor which evaluates the analog voltage.
- the connection between plunger 1.4 and ring magnet 4 is released and the magnet can move freely rotating speed. He turns his south pole to the sensor 3.
- suitable resilient or by opposite polarity arranged magnets of the ring magnet 4 is moved back to the starting position. This state corresponds to the representation in f). It is advantageous to weight the magnet 4 with weights in order to generate moments of inertia that can be felt in the key.
- the voltage amplitude generated by the spinning of the ring magnet 4 at the output of the sensor 3 is evaluated by the processor so that either a voltage measurement or a time measurement is terminated at the moment of dropping the amplitude and the data values achieved are converted as valid into dynamic values.
- FIG. 3a to 3 c different versions for the arrangement of sensor magnet 4 are shown.
- the sensor 3 and a magnetic flux reinforcing conductor 3.2 are arranged on the printed circuit board 3.1.
- circular segments of two antipolar magnets are provided.
- the device resembles a hammer movement and requires only short movements, which counterbalances weight.
- Figure 3b also two magnets are used. In this case, two magnets arranged opposite to each other move vertically past the sensor 3. This arrangement is particularly suitable for the playing modes piano and harpsichord.
- the arrangement shown in Figure 3c requires only one magnet in a vertical polarity. It is easy to perform and well suited when playing only organ.
- FIG. 4 explains the structure and mode of operation of a comparator unit 5.
- a first key is assigned the sensor 3a and the next key the sensor 3b. While the outputs of the sensors 3 are combined with the upper inputs of the comparators K1 ... K7, the lower comparator inputs are connected to the lines of the reference voltage bus, to which the setpoint voltages U set [1..7] are applied. Due to different setpoint voltages, a different switching state is produced when the sensor voltage changes at the outputs of the comparators at different times (key positions).
- the seven switches thus formed are assigned to certain functions. For this purpose there are three switch groups SG.
- the comparators K2 to K4 and K5 to K7 each form a switch group SG.
- Each switch group SG consists of a pair of switches SP and a reversing switch with the comparator K4 or K7.
- the comparator K1 is provided for all switches as a general reset in the idle state of the key and has the highest priority for all switches. Taking into account the hierarchy that within a switch group, the target voltage U is always higher or lower from one to the next comparator, the switch distances can be changed arbitrarily. It is even possible to move the two groups of switches so that they overlap or are pushed into the reversed position. If one of the switch groups is moved into the area outside the voltage swing of the sensor, this will be ineffective.
- FIG. 5 shows the function of the keyboard logic 6.
- the functioning the modules sensor 3, comparator unit 5, target voltage unit 8 and Data field 9 corresponds to the mode of action described above.
- the external ones Digital signal processors 7 are located with their address lines ADR and Data lines DAT on the keyboard logic 6 on. About the data field 9 takes place a selection which digital signal processor 7 is driven.
- optional DSPOrgel 7.1, DSPCembalo 7.2 and DSPDYN (Piano) 7.3 are provided, i.e. they do not have a common data bus. This has the advantage that different sound expander can be controlled by the keyboard, even organ and piano at the same time. To imitate a two-note harpsichord can, two switch groups are available.
- Displaceability of the switch groups can be a selection and arrangement of simulated string choirs. If pulled in this way no register is, so no pressure point is noticeable. In a frequently practiced dynamic stop type is the time between two switching stages evaluated.
- inventive keyboard logic that is done between the comparator switch positions K3 and K5. At a Combination piano organ becomes the organ sound with the piano tone on comparator K5, who otherwise with completion of the pressure point on comparator K3 lies.
- the comparators K4 and K7 play in the sound circuit one subordinate role.
- FIG. 6 shows the extraction of the pressure points and the sound input when playing in organ mode.
- the switch positions of the comparators K1 to K4 are at a key movement down (down) and after the attack back up (up) as symmetrical steps.
- the comparator K1 releases the sound channel by its L signal.
- the comparator K2 sets a flip-flop register FF and thus switches on the pressure point down DPd for the magnet driver MT 13.1.
- the comparator K3 then resets and ends the pressure point time.
- a flip-flop register is set for the activation of the organ sound.
- an active signal is present for the organ duration t O for the DSPO.
- the Tastenentiefgang reaches the switching position K4, with the also a flip-flop register is set, which is only set back by the comparator K1.
- the switch assignment is inverted; because now the comparator K3 sets the flip-flop register and the comparator K2 resets. This ends the organ sound to a hysteresis.
- the pressure point signal connected in this way now appears, determined by the comparator K4, at the output DPu MT13.2, the pressure point up solenoid driver.
- the pressure point strength can thus generally be weaker or completely switched off since both pressure point outputs can be controlled separately. This creates a one-way pressure point.
- the comparator K1 In the rest position of the button, the comparator K1 is in the H state.
- Figure 7 shows the entire switch pulse staircase for the comparators K1 to K7. This corresponds to the style of a double-choir harpsichord. Both switch groups are activated. It is assumed a 4-foot and an 8-foot string choir. It is common that the strings lying on top of each other are not synchronously but are touched one after the other. This harpsichord personality is taken into account with a second, similar pressure point. The basic sequence corresponds to that described in the explanation of the pressure point recovery in the organ of Figure 6. In the character of the harpsichord there are significant differences to the organ. The harpsichord has only evanescent strings, but a dynamic attack is hardly possible.
- a typical body noise is produced, which is simulated by a special noise sample and mixed with the tone sample t C4 '/ 8' according to the duration of the first pressure point impulse t A. For this reason, the pressure point pulse is output at the data output DATC, the longer it is the less noise it means. Only a spontaneous short pressure impulse is suitable for the presentation of this impact sound. Unlike the organ tone, the harpsichord tone t C is not terminated by the comparators K2 or K5.

Description
Nachdem der Tastenhebel 1 die Position d) erreicht hat, wird die Verbindung zwischen Stößel 1.4 und Ringmagnet 4 gelöst und der Magnet kann sich frei drehend beschleunigt bewegen. Dabei dreht er seinen Südpol dem Sensor 3 zu. Durch geeignete federnde oder durch gegenpolig angeordnete Magnete wird der Ringmagnet 4 wieder in die Ausgangsposition zurück bewegt. Dieser Zustand entspricht der Darstellung in f). Es ist vorteilhaft, den Magnet 4 mit Gewichten zu beschweren, um ein Trägheitsmomente zu erzeugen, das in der Taste fühlbar ist. Die durch das Schleudern des Ringmagneten 4 am Ausgang des Sensors 3 erzeugte Spannungamplitude wird vom Prozessor so bewertet, dass im Moment des Absinkens der Amplitude entweder eine Spannungsmessung oder eine Zeitmessung beendet wird und die erreichten Datenwerte als gültig in dynamische Werte umgewandelt werden.
Bei der in Figur 3b dargestellten Anordnung kommen ebenfalls zwei Magnete zum Einsatz. In diesem Fall bewegen sich zwei gegenpolig angeordnete Magnete senkrecht am Sensor 3 vorbei. Diese Anordnung ist besonders geeignet für die Spielmodi Piano und Cembalo.
Die in Figur 3c gezeigte Anordnung erfordert nur einem Magneten in senkrechter Polung. Sie ist einfach ausführbar und gut geeignet, wenn nur Orgel gespielt wird.
