Description

Description: TECHNICAL FIELD OF THE INVENTION The present invention is based on the degree of deviation of contact signals from at least two contacts that are sequentially conducted with a time shift due to a performance operation, and the contents of a musical sound, for example, volume and sound. The present invention relates to a touch response device that controls high and harmonic components.

[Prior Art and its Problems] Conventionally, in such a touch response device, a time lag from the turning on of a contact that conducts first to the turning on of a contact that conducts later is counted, and this is touched by a decoder or the like. I was trying to convert it to data (Japanese Patent Publication Sho 53-441
8, Japanese Patent Publication 53-5545).

In this case, assuming that the maximum measurable time of the displacement of the two contacts is 40 ms and the resolution of the displacement time is 80 μs, data of 500 states are required in total, and a 9-bit measurement counter is required for that. Become. When this is arranged in each key, if there are 88 keys in total, a counter equivalent to 9 × 88 = 792 bits is required, and the number of bits for converting this to touch data also increases accordingly, and the circuit scale increases. Grows very large.

However, there is a difference in the rate of change of the musical sound due to the difference in the key pressing speed at each point when the key is tapped fast, normally, and slowly.For example, when the key is tapped quickly, the difference in key pressing speed is small. However, it has a great influence on the change of the musical tone, but on the contrary, when tapping slowly, even if the difference in the key pressing speed is large, it does not affect the change of the musical sound so much, so the time resolution of the key pressing speed is When tapping slowly, the time resolution of the key pressing speed may be reduced.

Also, the count value of the count performed at a constant speed is taken in at the ON time of the contact that conducts first and the ON time of the contact that conducts later, and the touch data is obtained based on the difference between the two count values. It is a thing (Japanese Patent Publication Sho 58
-See No. 57119). However, even with this stuff,
Since counting is performed at a constant speed, there is no difference in that the time resolution of the key pressing speed is wasted.

[Object of the Invention] The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a touch response device that can obtain a touch response effect that matches an actual performance even if the circuit scale is small. Especially.

[Summary of the Invention] In order to achieve the above-mentioned object, the present invention provides: at least first and second contacts that are sequentially operated with a time lag due to operation of one operator; and operations of the first and second contacts. Counting means for counting at a constant speed with a cycle smaller than the longest time capable of measuring time lag, a predetermined value indicating a calculation form in response to the operation of the first contact, and the count of the counting means at that time Storage means for storing information and counting is performed every time the count information of the counting means reaches a predetermined value, and when the count value reaches a value corresponding to the predetermined value in the storage means, the predetermined value is changed. The changing means, the reading means for reading the count information at that time of the counting means in response to the operation of the second contact, and the reading means configured to be operable in a plurality of different operation modes. Calculating means for calculating touch information based on the count information read by the taking means and the count information stored in the storing means, in a calculation form corresponding to a predetermined value stored in the storing means, and outputting touch data; It is characterized by having.

[Embodiment] <Outline> In this embodiment, the basic cycle counter 4 corresponds to the counting means, the storage unit 3 corresponds to the storage means, the mode changing unit 11 and the data converting unit 10 correspond to the changing unit and the converting unit, respectively. The maximum measurable time of the displacement of the two contacts is 40 ms, the predetermined value stored in the storage unit 3 substantially corresponds to the mode data M and the cycle number data F, and the subtraction content of the data conversion unit 10 is shown in FIG. I'm getting bored. A list of touch data TCD is shown in FIG. 10, and the position on the left vertical axis in the figure corresponds to when the first contact is on, and at the position where the second contact is on along the elapsed time on the horizontal axis. The touch data value is the desired value.

Touch data TCD according to the above mode data M (7/6 to 1)
Is stepped as shown by the two-dot chain line, and is further stepped as shown by the dotted line by the cycle number data F (16 × F to 4 × F), and the data D of the basic cycle counter 4 when the first contact is on The difference is RC-D from the data RC of the basic cycle counter 4 when the second contact is on, and is graded as shown by the solid line. The resolution (subtraction speed) of the touch data TCD for each step is 1 (subtraction) per "1φ" of the basic cycle counter 4 in modes "7/6" and "5", and "2 prefecture" in mode "4". 1 (subtraction), 1 (subtraction) per "4φ" in the mode "3", 1 (subtraction) per "8φ" in the mode "2". Due to this decrease in resolution, even though the longest time to obtain the touch data TCD is long, the maximum value of the touch data TCD is only "127" and the number of digits is small, so the circuit scale can be reduced accordingly. .

<Structure> Overall Circuit Structure FIG. 1 shows the overall circuit structure of the touch response device. In FIG. 1, reference numeral 1 denotes a key state processing device, and this device 1 corresponds to each operation key of a keyboard (not shown). Key code KC,
Two contact signals corresponding to each ON state of the two contacts that are electrically connected after the operation keys are sequentially shifted are generated and sent to the control / calculation unit 2.

In the control / arithmetic unit 2, when the contact signal of the first contact is given, a predetermined value of "7" or "6" is set in the storage unit 3 as mode data M _{0 to} M ₂ , and the basic cycle counter at that time is set. The count data D _{0 to} D _{4 of 4} are also set in the storage unit 3.

The basic cycle counter 4 is a 5-bit T _{0 to} T ₄ 32-bit counter and is counted by the clock signal φ having a cycle of 80 μs, and the count time of one cycle is 80 μs × 32≈2.5 ms. Is the longest time that can be measured
It is possible to count 40 ms at a constant speed for 16 cycles.

The mode data M (predetermined value) set in the storage unit 3 is
The count of the basic cycle counter 4 is subtracted every cycle, but this subtraction speed is 1/2, 1/4, with the passage of time.
It is delayed by 1/8.

Then, when the contact signal of the second contact is given from the key state processing device 1, the count data RC of the basic cycle counter 4 at that time is read out, and the count when the first contact is stored in the storage unit 3 is turned on. The difference RC-D from the data D is obtained. This difference RC-D is also reduced to 1/2, 1/4, 1/8 according to the value of the mode data M at that time.

Touch data is calculated by the control / calculation unit 2 using the data RC-D and the mode data M and the like, and is output.

The storage unit 3 has a storage capacity of 88 addresses corresponding to 88 keys, and the same data as the key code from the key state processing device 1 is designated as address data at each address.
In changing the subtraction of the mode data M therein, the addressing of the storage unit 3 is performed based on the processing point data SP from the processing pointer 5 which counts 88 steps with 7 bits. The processing pointer 5 counts 88 cycles of one cycle during one cycle of 32 cycles of the basic cycle counter 4, counting is started by a carry signal from the basic cycle counter 4, and incremented by an increment signal from the control / arithmetic unit 2. Will be done.

The structure of the storage data at one address of the storage unit 3, the structure of the count data RC of the basic cycle counter 4, and the structure of the processing pointer data SP of the processing pointer 5 are as shown in FIGS.

Configuration of Control / Calculation Unit 2 FIG. 2 shows the configuration of the control / calculation unit 2. Reference numeral 6 in the figure denotes a key counter unit having a 7-bit configuration, which starts counting at the rising edge of the clock signal φ given to the basic cycle counter 4, and within a period of the clock signal φ 88 to 0 to 87. The key number data for the key is output. The key number data is sent as address data to the storage unit 3 via the storage control unit 7, and is also given to the decoder unit 8 and the mode setting unit 9.

The key code KC from the key state processing device 1 and a contact signal of the first or second contact are given to the decoder section 8. When the key code KC matches the key number data, the key code KC The one given with
In the case of the contact signal of the contact, the start signal S1 is output, and when the one given together with the key code KC is the contact signal of the second contact, the end signal S2 is output. This start signal
S1 and the end signal S2 are given to the storage unit 3 via the storage control unit 7 as a command signal and a read command signal, respectively, the signal S1 is given to the mode setting unit 9 as a drive command signal, and the signal S2 is a data signal. It is also given to the converter 10 as a drive command signal.

The mode setting unit 9 is also provided with processing point data SP indicating the address where the storage unit 3 is subtracting from the processing pointer 5, and when the start signal S1 is given, the operation key data When the key number is given from the key counter unit 6 and the processing point data SP is greater than or equal to the key number, the mode data “6” is output. Conversely, when the processing point data SP is less than the key number, the mode data “7” is output, and the storage control unit 7
It is written in the storage unit 3 together with the count data D at that time from the basic cycle counter 4 via. There is a case where "7" is set in this way, because the mode data M is subtracted every 32 cycles of the basic cycle counter 4, but when the processing point data SP is less than the key number, This is to prevent the processing point data SP from being immediately subtracted in agreement with the key number within one cycle, and the subsequent subtraction processing to proceed “1” faster.

The mode data M and the count data D written in the storage unit 3 are read by using the data from the processing pointer 5 as a read address, and the mode change unit 11 via the storage control unit 7.
The basic cycle counter 4 is sequentially subtracted for each cycle of the basic cycle counter 4, and the data from the processing pointer 5 is directly written as a write address. The mode changing unit 11 outputs an increment signal to the processing pointer 5 for each subtraction process to proceed to the subtraction process of the next data M in the storage unit 3.

The data conversion unit 10 is driven when the second contact point to which the end signal S2 is applied is turned on, and the mode data M and the count data D read from the storage unit 3 at this time and the count data RC of the basic cycle counter 4 at this time as well. Create and output touch data based on and.

Configuration of Mode Change Unit 11 The mode change unit 11 receives the carry signal of the basic cycle counter 4 as the start signal of the subtraction process, and outputs the all-key end signal after the count process of 88 steps of the key counter unit 6. Is given as the enable signal E, and the subtraction process of the mode data M is performed only while the enable signal E is given. The all-key end signal is given to the key counter unit 6 itself as a count stop signal, and when the count of the key count unit 6 is started at the next rise of the clock signal φ, the enable signal E is sent to the mode changing unit 11. The subtraction process is interrupted because it is no longer given. Therefore, as shown in FIG. 7, in the first half of one cycle of the clock signal φ, the key counter unit 6 performs the key number count process for 88 keys, that is, the data access process of the storage unit 3 according to the operation key, In the latter half of one cycle of the clock signal φ, the mode changing unit 11 performs the subtraction process of the mode data M in the storage unit 3. This subtraction process is performed for all 88 keys, but for almost one cycle of the basic cycle counter 4.
It takes 32φ and the data access processing of the storage unit 3 is performed by the storage unit 3.
It is considerably faster than the subtraction process of.

FIG. 8 shows the contents of the subtraction process of the mode changing unit 11, in which the old data M, D on the left side of the figure to the new data M, D in the middle are shown.
The subtraction process to
It is carried out every time, and the mode data from the top row "7" to "6"
And only the subtraction from "6" to "5" is 32φ or less as shown in FIG. 6 described later. The contents of the subtraction process of the mode data M will be described below.

The time for which each mode data M is held increases from 2 times, 4 times, and 8 times as it goes from “7/6” to “2”.

“7”: Up to 32φ until it becomes “6” as shown in FIG.
Approximately 2.5 ms is required, and the maximum 2.5 ms is retained and subtracted to "6".

"6": Maximum 32φ until it becomes "5", so maximum 2.
It is held for 5ms and subtracted to "5".

“5”: 32φ until reaching “4”, so it is held for 2.5 ms and subtracted to “4”.

"4": 5 cycles since 2 cycles are 64φ until it becomes "3"
Is held for a period of time and subtracted to "3". In this case, the last digit of the count data D is replaced with the cycle data F (1st cycle = 0.2 cycle = 1) which indicates which cycle of the above two cycles.

“3”: 4 cycles of 128φ until reaching “2”, so 10m
It is held for s time and subtracted to "2". In this case, the last two digits of the count data D are replaced with the cycle data F (1st cycle = 00 to 4th cycle = 11) indicating which cycle of the above 4 cycles.

"2": 20m because it is 8 cycles of 256φ until it becomes "1"
It is held for s time and subtracted to "1". In this case, the last 3 digits of the count data D are cycle data F (1st cycle = 000 to 8th cycle = 111) indicating which cycle of the above 8 cycles.
Is replaced by

"1": Since the subtraction is not performed thereafter, it is always held as "1".

In this way, the subtraction speed of the mode data M is 1/2, 1/4, 1 /
The time length that each mode data M can take is shown in the lower part of FIG. 10 described later.

Configuration of Data Converter 10 FIG. 9 shows processing formulas (1) to (13) for the conversion processing for obtaining the touch data TCD of the data converter 10. FIG. 10 shows the value of the touch data TCD which is the result of this processing. Shows a list of. From the first contact on (S1) to the second contact on (S2
The time until the time) is roughly composed of the mode data M indicating the number of count cycles of the basic cycle counter 4 between S1 and S2 and the lower cycle number data F of the count data D.
Although it is stepped as shown by the dotted line in FIG. 10, more specifically, the data D of the basic cycle counter 4 when the first contact is on and the RC of the basic cycle counter 4 when the second contact is on, which is a fraction of the above frequency. With the difference RC-D, it will be graded as shown by the solid line in FIG. The chain double-dashed line in Fig. 10 is the touch data TCD that is graded by the mode data M only.
Is shown.

In Fig. 10, the vertical axis on the left side of the figure is the first contact on time (S1), and the touch data value at the position where the second contact is on (S2) is set along the elapsed time on the horizontal axis. It becomes a value. Regarding the mode data M value on the horizontal axis of "7/6", it is not limited to 32φ = 2.5 ms as shown in FIG. 6, and the horizontal axis of FIG. 10 shows the key code KC value and the processing point data SP value. Shows the case where they match, and it is necessary to change the size of the part of "7/6" according to the difference in both KC and SP values and shift only the horizontal axis in the horizontal direction.

The processing equations (1) to (13) in FIG. 9 will be described below.

(1) L = RC-D: Difference RC between the data D of the basic cycle counter 4 when the first contact is on and the data RC of the basic cycle counter 4 when the second contact is on, which is a fraction of the above-mentioned cycle number
D is as it is.

(2) L = RC-D: Same as the above formula (1).

(3) L = RC-D + 32: At this stage, processing point data S
P value> key code KC value, C = 0, and the processing point data SP value changes from "88" to "0" as shown in the upper part of FIG.
Since the count value of the next cycle is returned to, the 32 for one cycle is corrected.

From the equations (1) to (3), touch data TCN = f
(N, L) is {32 × (N−2) +31} −L = {32 × (5
-2) +31} -L = 127-L, and the fractional "L" is subtracted from the maximum value "127" of the touch data TCD.

(4) L = RC-D + 32: Same as the above expression (3). As shown in point A in the upper part of FIG. 6, the key code KC value is young (“20” in the figure), and the mode is the same as when mode data M = 6. Touch data TC that the key code KC value is large (“80” in the figure) and still in mode “6”.
This is to make the D values equal. This is fundamental for each of the formulas (5) and (6), (8) and (9), and (11) and (12) described below.

(5) L = RC / 2-D / 2 + 16: This is an expression obtained by halving the expressions (3) and (4). This is because the subtraction speed becomes half in mode "5" as shown in FIG. 10 compared to mode "7/6".

(6) L = RC / 2−D + 16 + (16 × F): “D / 2” is “D” in the above formula (5) because the mode “4” has a 5-bit count. This is because only the upper 4 bits of the data D value are taken out and the value is shifted by 1 bit to the lower half. (16 × F) is touch data TC
This is a correction formula for dividing the value of D “32” into two cycles of the cycle data F = 0 and 1 and subtracting “16”.

(7) L = RC / 2-D + 16 + 16: Almost the same as the equation (6), and the correction value is "16" because it is the first cycle of the cycle data F = 0.

(8) L = RC / 4-D / 2 + 8: Equation (6) and (7) are halved. This is because the subtraction speed is further halved in the latter half of the mode “4”. (16 × F), there is no correction value of 16 because the subtraction of the new 1/4 subtraction speed starts here.

(9) L = RC / 4-D + 8 + (8 × F): “D / 2” is “D” in the above equation (8) because the count data value is shifted further 1 bit to the lower order. And then 1 / three bits
This is because the value is 2. (8 × F) is a correction formula for dividing the touch data TCD “32” value into four periods of the period data F = 00, 01, 10, 11 and subtracting “8” by each.

(10) L = RC / 4-D + 8 + {8 × (F + 1)}: The period data F is incremented by 1 in the above formula (9).
This is because when the key code KC value of C = 1.ltoreq.the processing point data SP value, the key code KC value of C = 0> the processing point, the cycle data F has a difference of one cycle.

(11) L = RC / 8-D / 2 + 4: This is a formula obtained by halving the formula (8). The correction values of (8 × F) and 8 × (F + 1) do not exist because the subtraction speed is further halved in the last one cycle of the mode “3”.

(12) L = RC / 8−D + 4 + (4 × F): “D / 2” is “D” in the above formula (11) because the count data value is shifted further 1 bit to the lower order. Then 1 of 2 bits
This is because the value is 2. (4 × F) is the cycle data F = 000, 001, 010, 01 for the touch data TCD “32” value.
It is a correction formula for subtracting “4” by dividing into eight cycles of 1, 100, 101, 110, 111.

(13) L = RC / 8-D + 4 + {4 × (F + 1)}: The handwritten data F is incremented by 1 in the above expression (12).
This is because when the key code KC value of C = 1.ltoreq.the processing point data SP value, the key code KC value of C = 0> the processing point, the cycle data F has a difference of one cycle.

As shown in the processing II of FIG. 9, when the fractional data L exceeds “32” for one cycle, the difference between L and “32” is halved and this is set to “L”. I am trying to correct it.

<Operation> Outline of calculation of touch data TCD The method of obtaining touch data TCD described above can be summarized based on Fig. 10 as follows.

In FIG. 10, the touch data TCD is f in FIG.
(N, L) = {32 × (N−2) +31} −L, but the maximum value of touch data TCD is {32 × (5-2) +3.
1} = 127 (“1111111”), and is −32 at the first first cycle 32φ to become “95”, and is made −16 at the next second cycle 64φ and third cycle 94φ. "79""6"
3 ”, and the following 4th period 128φ to 7th period 224φ
At each time point, it is changed to -8 and becomes "55", "47", "39" and "31", and again at the time point from the eighth cycle of 256φ to the 15th cycle of 480φ, -4 is changed to "27", "23" and "19". "15""11"
It becomes "7""3""0".

In this way, the subtraction speed of the touch data TCD becomes 1/2, 1/4, and 1/8 with the passage of time.

Correspondingly, as shown in the circle in Fig. 10, in the first cycle, 32φ is used for -32, so the touch data TCD is 1φ for -32.
However, in the 2nd and 3rd cycles, it is -32 in 64φ, so it is -1 in 2φ, and in the 4th to 7th cycles it is -32 in 128φ.
Therefore, it is decremented by 1 in 4φ and 256 in the 8th to 15th cycles.
Since φ is -32, 8φ is -1. Therefore, the resolution of the touch data TCD with respect to the key pressing speed becomes lower as the key pressing speed becomes slower and the time from the first contact on to the second contact on becomes longer.

Touch data TCD per 1
When processed to the end with the resolution of 1, the straight line having the characteristic shown by the inclination of the conventional example in FIG.
The maximum value of will jump from "127" to "472" all at once, and the number of digits of touch data TCD will increase from 7 bits to 9 bits, but the circuit scale will also become large,
The present invention eliminates such a problem.

Specific Example of Calculation of Touch Data TCD Next, a specific calculation process for calculating the touch data TCD will be described.

FIG. 11 shows four specific examples for obtaining the touch data TCD. Now, the key code KC is "0""25""50" 30.
It is assumed that the first contact is turned on when the key is operated and the value of the basic cycle counter 4 is "6" and the value of the processing pointer 5 is "30". Then, since only the key code “50” has a key code value larger than the value “30” of the processing pointer 5, the mode data set at the address “50” of the storage unit 3 becomes “7”, and the others “6”. It will be. The count data D is all "6" because the value of the basic cycle counter 4 is "6". Then, when the processing pointer unit 5 becomes "50", the data M and D at the address "50" of the storage unit 3 are read to the mode changing unit 11, and the mode data M is changed from "7" to "6". .

Next, in the next cycle, the processing pointer 5 becomes "0".
Every time it becomes “25” or “50”, the address of “0” in the storage unit 3,
The mode data M at the addresses "25" and "50" are rewritten to "5" and subtracted, and thereafter, the data at the addresses "0", "25" and "50" in the storage unit 3 are cycle by cycle. Is rewritten and subtracted.

It is assumed that when the value of the basic cycle counter 4 of the third cycle is "10" and the value of the processing pointer 5 is "20", the second contacts of the keys of the key codes "0" and "50" are turned on. At this time, the mode M “4” and the count D “00110” are set in the address “0” of the storage unit 3, and the mode M is set in the address “50”.
"5" and count D "6" are set. From this, when the touch data TCD is obtained, the key with the key code “0” is obtained based on the equation (6) in FIG. 9 and the key with the key code “50” is obtained based on the equation (5) in FIG. 9. Both fractional data L =
18, N = 4, and both touch data TCDs are "10011
01 (77) ”.

Thus, even if the setting data when the first contact is on is different, the same touch data TCD can be obtained based on the value of C in FIG. 9 at the same timing when the second contact is on.

In addition, the value of the basic cycle counter 4 in the fourth cycle is "3.
It is assumed that the second contact of the key with the key code "25" is turned on when the value of the processing pointer 5 is "0" and "88". At this time, the mode M “4” and the count D “00111” are set in the address “25” of the storage unit 3. From this, when the touch data TCD is obtained, the key with the key code “25” is obtained based on the equation (6) in FIG. 9, and the fractional data L = 8, N =
3 and the touch data TCD becomes “0111001 (57)”.

In this case, assuming that the second contact is turned on when the value of the basic cycle counter 4 is "6" and the value of the processing pointer 5 is "10", the arithmetic expression becomes the expression (8) and the fraction data L = 8, N = 3, and touch data TCD is "011
0111 (55) ”. Here, the value of the basic cycle counter 4 is advanced by "8", and the difference of the touch data is "8".
It is 1/4 of "2".

In this way, the touch data TCD corresponding to the time interval between the first contact on and the second contact on can be obtained.

The mode data M and the number-of-cycles data F may be grouped into the 4-bit mode data M (15 to 0), but the effective bit of the count data D becomes smaller as the resolution is lowered, and the vacant bits are correspondingly empty. Period number data F
If it is applied to the bit of, the number of bits of the data M and D required to obtain the touch data TCD can be reduced.

In addition, the formula for calculating the touch data TCD is f (N, L) above.
= (32 × (N−2) +31} −L not limited to the arithmetic expression, for example, f (N, L) = {32 × (N−2) +31} + (32−
L) and the value of N is incremented by -1 with respect to the value of FIG. 9 to make it look like an addition formula. In short, as shown in FIG. 9, the value of the touch data TCD changes with time. Any calculation form may be used as long as the resolution decreases as the resolution decreases.

Furthermore, the present invention is applicable to electronic string instruments other than the electronic keyboard instrument, and is not limited to the above embodiments.

[Effects of the Invention] As described in detail above, according to the present invention, the deviation of two contacts is counted by a counter having a count cycle smaller than the maximum measurable time, and when the first contact is on and the second contact is on. While counting the count value, the predetermined value stored when the first contact is turned on is changed in synchronization with the passage of the count cycle of the counter, and the first and second contacts are changed in an arithmetic form corresponding to the changed predetermined value. Since the touch data is configured to be calculated and generated based on the count value stored when it is turned on, it is possible to generate touch data that changes non-linearly with respect to the key pressing speed like a natural musical instrument. In addition, there is an advantage that a counter having a large number of bits for continuously counting in a fixed direction from the start of key depression to the end thereof is not required.
