Detailed Description
The technical solution of the present invention will be explained below with reference to the accompanying drawings.
As shown in fig. 2, the present invention provides a chord tone output control method, which may include the following steps:
s1, acquiring a function model for controlling the chord tone output circuit and the address of a storage unit for storing the chord tone array; the function model is packaged with control parameters corresponding to array elements of the chord tone array;
the chord tone output circuit in this step and other parts of the present invention may be the chord tone output circuit shown in fig. 1, or may be other types of circuits that perform chord tone output by using similar principles.
The functional model may be used to control the volume, pitch and/or duration of individual notes of a chord tone output by the chord tone output circuit. In one embodiment, the control parameters of the function model may include a value of the current flowing through the chord tone circuit, a frequency of a discharge voltage of the chord tone circuit, and a charge and discharge time of the chord tone circuit. Wherein the current value is used for controlling the volume, the frequency of the discharge voltage is used for controlling the tone, and the charging and discharging time is used for controlling the duration of the note. Thus, in one embodiment, the current value may be set according to the volume of each note in the chord tone; the frequency of the discharge voltage may also be set according to the pitch of each note in the chord tone; the charge and discharge time may also be set according to the duration of each note in the chord tone.
In one embodiment, the form of the chord tone array may be the following form:
{ array length, frequency 1, charge time 1, discharge time 1, frequency 2, charge time 2, discharge time 2, … …, frequency n, charge time n, discharge time n, … … }, where n is a positive integer. The length of the array may be set according to the number of notes of the chord tone, and assuming that m (m is a positive integer) notes are included in the chord tone, the length of the array may be set to m, and for convenience of subsequent modification of the array, for example, a case where notes are added to the array may occur, and the length of the array may also be set to a value greater than m.
Control parameters corresponding to the array elements of the chord tone array may be set in the function model, for example, when the chord tone array includes a frequency, a charge time, and a discharge time, the control parameters correspondingly include the frequency, the charge time, and the discharge time.
S2, calling corresponding chord tone arrays from the storage unit according to the addresses, and respectively assigning the array elements to corresponding control parameters in the function model;
the addresses of the memory locations storing the chord tone arrays may be stored in an address register, which may be pointed to by a pointer tabMusic1 when reading the addresses. This pointer tabMusic1 may point to 0 in the initial case. Another pointer tabMusic2 may be set in the function model, and the value of pointer tabMusic1 may be assigned to pointer tabMusic 2. In this way, the function model and the addresses of the chord tone arrays call the chord tone arrays to the storage units corresponding to the addresses.
And when assigning, assigning array elements in the chord tone array to corresponding control parameters in the function model. For example, a value corresponding to a frequency in the chord tone array may be assigned to a parameter representing the frequency in the control parameters; values corresponding to the charging time in the chord tone array can be assigned to parameters representing the charging time in the control parameters; values corresponding to the discharge time in the chord tone array can be assigned to parameters representing the discharge time in the control parameters; and so on.
In one embodiment, when the address of the storage unit storing the chord tone array is obtained, a plurality of addresses of the chord tone array can be obtained; wherein each address corresponds to a chord tone array. In this case, when the corresponding chord tone array is called from the storage unit according to the address, one address can be randomly selected from the plurality of addresses; calling the chord tone array from the storage unit corresponding to the selected address; or sequentially selecting one address from the plurality of addresses according to the arrangement order of the plurality of addresses; and calling the chord tone array from the storage unit corresponding to the selected address. In the first mode (random control mode), one of the chord tone arrays may be randomly selected to be assigned to the control parameters of the function model, and in the second mode (sequential control mode), one of the chord tone arrays may be sequentially selected to be assigned to the control parameters of the function model. After the value is assigned, step S3 may be performed. If the random control method is selected in this step, in step S3, after the group of chord tones is output, the step of randomly selecting one address from the plurality of addresses may be returned to, and a group of chord tones may be randomly selected again for output. If the sequence control method is selected in this step, in step S3, after one group of chord tones is output, the next chord tone array of the current chord tone array can be selected for output. The current chord tone array is the chord tone array which is played at present, and the next chord tone array is the chord tone array which corresponds to the next address of the address corresponding to the current chord tone array. Schematic diagrams of the random control manner and the sequential control manner are shown in fig. 3(a) and 3(b), respectively. Through the two modes, the multi-head chord tones can be automatically played, user control is not needed, and user operation is simplified.
In one embodiment, if neither chord tone stored in the system meets the requirements of the user, the chord tone can be set by the user. Specifically, an input parameter setting instruction may be received; and setting array elements of the chord tone array according to the parameter setting instruction. When the array elements are respectively assigned to the corresponding control parameters in the function model, the set array elements of the chord tone array can be respectively assigned to the corresponding control parameters in the function model.
In an embodiment, a plurality of empty arrays may also be preset, a certain storage space may be allocated to the empty arrays in advance, and an address may be allocated to each empty array.

In this way, a chord tone timing output effect can be achieved.
The timing control instruction can also comprise the repetition frequency and/or repetition times of the timing output chord tone, and the chord tone output circuit can be controlled to output the corresponding chord tone according to the repetition frequency and/or repetition times. The repetition frequency includes no repetition, once per day, once per month, etc. The number of repetitions may be set to 3, 5, 10, etc. For example, when the reading time is set to 30 minutes and 25 seconds at 17.5.5.2016 and the repetition frequency is set to be not repeated, the chord tone output circuit may be controlled to output the corresponding chord tone when the reading time reaches 30 minutes and 25 seconds at 17.5.17.12.2016 last time, and then the chord tone is not output any more. When the reading time is set to 2016, 12, 5, 17, 30 minutes, and 25 seconds, and the repetition frequency is set to once per month, the chord tone output circuit can be controlled to output the corresponding chord tone at a timing of 30 minutes, 25 seconds per month of 17 No. 5.

Wherein the current value is used for controlling the volume, the frequency of the discharge voltage is used for controlling the tone, and the charging and discharging time is used for controlling the duration of the note.
