When the user advances in the frequency mixer by the correct login of login process, in the information-setting by user storage area of current storage 303, load and be provided with user's user key file 310.In user's the authority of login, load U account data 312 filename (3) is set file 330 (aftermentioned) is set.Afterwards, authorizing to carry out in user's the extent of competence according to the permissions data that in the information-setting by user storage area, is provided with and handling.In addition, determine that according to U definition SW data 313 that load and U preference data 314 function or the user of the manipulater of user's setting operation device group 253 preferably select the value of setting.The details of authority is described with reference to Figure 12 after a while.
Now scene storer 320 will be described.Scene storer 320 is the storage areas that are used for the contextual data shown in the storage map 2 that obtain in flash memory 102.In Fig. 3, " 1 " to " N " is scene number.Call again or the storage scenarios data by the operation shown in Fig. 2.When request when calling contextual data again, contextual data is read, and then it is stored in the various parameter storage area of current storage and according to the parameter value of contextual data and carries out Frequency mixing processing.When having specified scene n and indication storage scenarios data, the data of the various parameter storage area of current storage 303 are written to the contextual data n of scene storer 320.
Though provided the explanation of scene storer 320 above, this equally also is real to routine library.Term " routine library " refers to the data acquisition of parameter value group, and it is used for a plurality of parameter items that common being provided with can be the part of contextual data.For example, prepared routine library such as balanced device (EQ) routine library, compressor reducer routine library and effect device routine library.For example, if hypothesis scene storer 320 is effect device routine libraries, the parameter of the effect device of the frequency mixer of being realized by DSP 108 can be set jointly by data n being called again to current storage 303 then.On the contrary, but the position of designated program database data and the value of setting of the effect device that is provided with can be stored as the data n of routine library in current storage 303.Fig. 3 is illustrated in and provides routine library A and B among the RAM 103.
To illustrate now file 330 will be set.File 330 is set comprises user's service data that frequency mixer reads when each user logins frequency mixer into.Specifically, aforesaid read corresponding in the user's who writes on login the user key file 310 filename is set file 330 is set.The configuration information that defines all states how frequency mixer is set is stored in and is provided with in the file 330.File 330 is set to be stored in the storage medium identical with storing the user key file 310 that reads the user that file 330 is set.Specifically, because the user key file 310 of " keeper " and " guest " is stored in the flash memory 102, so the file that is provided with that reads by them is stored in the flash memory 102.Because other users' user key file 310 is stored in the USB storage 110, so their being provided with in the USB storage 110 that file is stored in them of reading.
File 330 is set comprises S title 331, system setting area 332, current memory block 333, scene memory block 334, routine library a-quadrant 335, routine library B zone 336 and another zone 337.The system setting area is the zone of retention system configuration information, and described system configuration information is stored in the system configuration information memory block in the current storage 303.Current memory block 333 is the zones that keep the information of the various parameter values in the various parameters memory block that is stored in current storage 303.Though current memory block 333 keeps the information-setting by user memory block, the user key file 310 that is provided with outside the file 330 keeps the information-setting by user that is stored in the information-setting by user memory block.Scene memory block 334 is the zones that keep contextual data, and described contextual data is stored in the scene storer 320 of flash memory 102 of frequency mixer.Routine library a-quadrant 335 and routine library B zone 336 are to keep to be stored in the routine library A of flash memory 102 and the zone of the routine library data among the B (320).Zone 337 is used to keep other data.Specifically, if file 330 will be set to be loaded in the frequency mixer, the data of system setting area 332 and current memory block 333 just are loaded in the zone of the current storage 303 among the RAM 103 so, the data of scene memory block 334 are loaded in the zone of the scene storer 320 in the flash memory 102, and the data in routine library a-quadrant 335 and routine library B zone 336 are loaded in the zone of the routine library A of flash memory 102 and B (320), control the operation of frequency mixer according to loaded data.
Dotted line 305-307 among Fig. 3 indication only has can carry out when carrying out the authority of handling the active user and is used to store/call or preserve/the described processing of loading data.Yet,, because when the user logins, must read user key file 310, so user key file 310 is arranged to allow to the loading in the current storage 303 (information-setting by user memory block) always.
The user of frequency mixer and their authority will be described now.The back can illustrate the detailed item of authority with reference to Figure 12.As mentioned above, " keeper " and " guest " is registered as the user that stipulates of frequency mixer.The keeper is the user with highest weight limit.Have only the keeper can be provided with and change guest's authority.Because it is the highest that the authority of " keeper " is fixed to, so even " keeper " can not change the authority of " keeper ".Anyone who comprises " guest " can not be provided with and change the authority of " guest ".The keeper can register " general user " and " high authority user's " new account." general user " and " high authority user " is group name.When each personal name in an account book is registered, can the designated user name whether be " general user " or " high authority user " just.The keeper can be provided with and change each personal user's of general user or high authority user authority.High authority user can be provided with and change high authority user's authority and general user's authority.Yet high authority user can be provided with and change their authority in giving high authority user's extent of competence.Each general user can consult their authority, but can not change their authority.Each general user even can not consult other users' authority.The difference that only has between general user and the high authority user is the authority that the general user can not change them, and high authority user can be provided with and change their authority.Other authority key element is based on other authority setting option in the permissions data.
Because permission or unallowed function are to control according to aforesaid each user's authority, so can suppress unskilled user's faulty operation and restriction field engineering's teacher (guest slip-stick artist) opereating specification, and other users outside the specific people that can also prevent to be responsible for handle specific parameter arbitrarily under the situation that a plurality of people are used alternatingly.Can also be easy to switch user's preferred setting.In addition, because when login, read the specific file that is provided with automatically,, the user of login do not worry the setting before frequency mixer just so can beginning to operate frequency mixer.
To illustrate now how the user logins in the frequency mixer of present embodiment into.As mentioned above, when the power supply of unblanking mixer, when the user uses user name " guest " login enters it automatically, start frequency mixer.If user expectation is used another user name login frequency mixer, then the user opens login button 251 and selects to select on the screen user name the user, and login enters frequency mixer thus.If the user opens exit button 252, when then login process is automatically performed by " guest ", therefore user name withdraws from frequency mixer, the user always can sign in in the frequency mixer, if and any other user except that " guest " withdraws from frequency mixer, Deng Lu user just is back to " guest " so.
Can remove USB storage 110 from frequency mixer and replace using login buttons 251 and exit button 252 to carry out logining/withdraw from processing by USB storage 110 being inserted into frequency mixer neutralization.Specifically, if will wherein store the USB storage 110 of user key file is inserted in the frequency mixer, then user list in the explicit user key file and user can sign in in the frequency mixer thus from the user of this user list selection login on screen.If remove USB storage 110 from frequency mixer, user name can withdraw from frequency mixer automatically so.Though high authority user can use USB storage 110 to create or compiles user key file 310, but they also can require to remove in the insertion mouth that has been inserted into frequency mixer at that time and wherein store the USB storage 110 of their user key file 310, and what replace it is to insert will to create or the target USB storage 110 of compiles user key file 310.Yet, if USB storage 110 is newly inserted the USB storage that replacement has been inserted in the frequency mixer, then, carry out the function of logining/withdrawing from because frequency mixer has when inserting or dismantle USB storage 110, the user of the new USB storage of inserting 110 login enters so the active user withdraws from.Therefore, though high authority user creates or compiles user key file 310, even but high authority user can not withdraw from yet when USB storage 110 is disassembled, even and will create or during the target USB storage 110 of compiles user key file 310 inserting, high authority user still remains the active user, and does not carry out new login process.
The feature of frequency mixer when the user logins will be described now.As mentioned above, when the user logined, whether the checking ID in frequency mixer detection user's the user key file 310 was corresponding with the frequency mixer administrator's password.Use the USB storage 110 of the key file 310 that wherein stores them, the user can login and use the frequency mixer that the keeper managed (that is, storing the frequency mixer of administrator's password) by the checking ID appointment in the user key file 310.In other words, the user can not login by with the different frequency mixer that the keeper managed of keeper of checking ID appointment.One or more frequency mixer that this management makes it possible to wherein to be provided with identical administrator's password are divided into a group with the one or more users with password identical with its checking ID.This user that can realize allowing belonging to a group can only use the management (that is, preventing that the user from using the frequency mixer that belongs to other group) of the frequency mixer that belongs to this group.The supvr of frequency mixer (promptly, under the situation about the keeper) changing, the key of the user key file 310 by changing " keeper " that keep in the frequency mixer only only just can be transformed into it frequency mixer of user's use that can be by belonging to new " keeper " group.
When the user logined into frequency mixer, the file that is provided with that filename is set of user's user key file 310 was read automatically and is provided with in frequency mixer, made the frequency mixer environment that can realize being suitable for the user immediately.Carry out to read according to user's the authority of login file is set.Specifically, if there is not the user of given login to load or call again the authority of data, even can not reads and be written to the data that are provided with in the file.Therefore, can share identical file being set and file is set and be shared, also can be implemented according to the various environment of described authority even give the user of different rights.
The process flow diagram of the performed process of CPU 101 when Fig. 4 a is the power supply of unblanking mixer.CPU 101 carries out initial setting up and activates the account of " guest " in step 402 in step 401.This is the user key file 310 of aforesaid reading " guest " and with the processing in the current storage 303 of the various data load of user key file 310.Then, in step 403, whether whether CPU 101 check will be provided with in the U account data 312 that filename is written to the user key file 310 that is read and have in flash memory 102 file be set.Filename is not set or file if there is no is set if also write, then aforesaidly be loaded in current storage 303 grades in step 404 all a predetermined initial setup file 330 with reference to Fig. 3.Here, suppose and use specific filename that predetermined initial setup file 330 is stored in the flash memory 102.Be written to reading in the user key file 310 and file is set and appearing in the flash memory 102 of guest if filename will be set, then all that file will be set in step 405 all are loaded in current storage 303 grades.
Then, in step 406, CPU 101 waits for up to the generation of one of variety of event and in the processing of step 407 execution according to a generation incident.When not having incident to take place or after step 407, CPU 101 carries out another processing and returns step 406 in step 408.The example of the incident of the processing that initiation will be carried out comprises that USB storage inserts or remove incident, fader (105) Action Events, manipulater (106) Action Events, communicate relevant incident and user's handover event with various external units.
According to above-mentioned process, when opening the frequency mixer power supply, under the situation of not carrying out any register, use " guest " to carry out automatic login process.
Fig. 4 b is the process flow diagram of the performed process of CPU 101 when the ON incident of the login button 251 of Fig. 2 takes place or when the insertion incident generation of USB storage 110.When the ON of login button 251 incident took place, CPU 101 began to carry out described process from step 414.In step 414, CPU 101 carries out the user and selects to handle.The user that Fig. 8 a is illustrated in step 414 demonstration selects screen 801.The radio button that uses as represent by " 811 " in Fig. 8 a for its keeper who stores user key file 310 in the flash memory 102 of frequency mixer main body shows." guest " is not shown.This is to allow the user except that " guest " to login into frequency mixer because open login button 251.From operator's the viewpoint of operation frequency mixer, use " guest " not carry out any login process.Also use the tabulation that is presented at the user name of the user key file 310 in the USB storage 110 that is connected with frequency mixer at that time by the radio button of " 812 " representative." 813 " represent the OK button, and " 814 " represent X button.The user uses a corresponding radio button to select user's login from the user who shows, and selects to handle by opening OK button 813 termination users.When X button 814 had been opened, the user selected to be counted as to cancel, and kept the user's of current login logging status under the situation of not carrying out any processing subsequently.
After step 414, CPU 101 determines whether that in step 415 state that is provided with that file is set that reads when the user in current login being logined made any change.When having made any change, CPU 101 carries out in step 416 and is used to preserve the processing that file is set.The back is elaborated to this processing with reference to Fig. 5 b.When in step 415 not to being provided with that file is made any change or after step 416, CPU 101 determines that in step 417 the checking ID in the new user's who selects the user key file 310 is whether consistent with the password of " keeper " of frequency mixer.If the two unanimity, CPU 101 determines that selected user is the correct user of frequency mixer, and verifies selected user's password in step 418.
Fig. 9 a represents selected user's password authentification screen 901.As the selected user name that shows of " 911 " representative, and display password input field 912, OK button 913 and X button 914.If the user is to password input field 912 input passwords and open OK button 913, CPU 101 carries out password authentification then.Details with reference to the processing of Fig. 5 a description of step 418.
If determine that in step 417 user's checking ID is different with the administrator's password of frequency mixer, then CPU 101 carries out administrator's password in step 419 and verifies processing, and carries out checking ID in step 420 and upgrade processing, advances to step 418 then.
Fig. 9 b is illustrated in the administrator's password checking screen 901 that step 419 shows.Because ID is different with administrator's password in checking,, CPU 101 determines whether described user is the suitable user of frequency mixer so showing the information 921 of the administrator's password of asking input mixer.The administrator's password of user's input mixer and open OK button 923 then.If inputed correct password, then CPU 101 carries out the processing in the checking ID district in the user key file 310 that uses the New Administrator Password who is input in the zone 922 to upgrade the user in step 420.Therefore, the user cipher that produces for another frequency mixer is used as the user key of required frequency mixer.Afterwards, CPU 101 advances to step 418 to carry out the password authentification of selected user.Though write user's checking ID again in step 420, can also allow the user to choose whether to rewrite checking ID.In addition when rewriteeing checking ID, because imported correct administrator's password and CPU 101 advances to step 418, so checking ID testing result is OK.
After step 418, CPU 101 activates the account of selected user in step 421.This is the processing that is used for the information of the user key file 310 of selected user is loaded into the information-setting by user memory block of current storage 303.Then, if CPU 101 determines that in step 422 permissions data that selected user has according to selected user loads the authority that file is set, and determine to be provided with in the user key file 310 that filename is written into the user and file is set and appear in the record storage area (flash memory or USB storage) identical with storing user key file 310, then CPU 101 loads in step 423 file being set and stopping described process of filename is set.If CPU 101 does not have to load the authority of file to be set and also not to write filename to be set or not to exist in same record storage at the definite selected user of step 422 file is not set, then CPU 101 does not carry out any further processing and stops described process.With reference to Fig. 5 b explanation file load being set handles.
When the insertion incident of USB storage 110 took place, CPU 101 carried out process same as described above.At first, in step 411, CPU 101 determines whether to create or the compiles user key.If be defined as is that then CPU 101 does not carry out any further processing and stops described process.When the user of login is keeper or high authority user, they can create or the compiles user key, and in identical situation, they can insert the USB storage of the user key that storage will edit or the USB storage that will store the new user key that will create therein, with the storer that replaces inserting.In this case, step 411 process is afterwards logined and is stopped in the insertion of CPU 101 uncertain USB storage 110 indication again.If in step 411 is not to create or the compiles user key, then whether there is user key file 310 in the USB storage 110 that CPU 101 determines inserting in step 412.If there is no the user key file 310, and then CPU 101 does not carry out any other processing and stops described process in step 413.If there is user key file 310, then CPU 101 advances to step 414.Processing subsequently is same as described above.Fig. 8 b represents that the user who shows in step 414 selects screen 802 when inserting USB storage 110.Inserting USB storage 110 can be counted as and have the intention that the user by USB storage 110 logins.Therefore, in step 802, CPU 101 shows as by the user list in the USB storage 110 of " 822 " representative.
Fig. 5 a is the process flow diagram that the password authentification of the selected user of step 418 is handled.In step 501, CPU 101 is presented at the password authentification screen 901 shown in Fig. 9 a.If detect the operation of input character in step 502, then CPU 101 is provided with input character in step 503 in password input field 912.Then, CPU 101 operates in step 504 test button.If do not detect push-botton operation, then CPU 101 turns back to step 502.If open X button 914, then CPU 101 definite password authentifications processing are cancelled and are stopped login process in step 505.In this case, all processing of the later step of CPU 101 cancellation step 418 and invoked procedure and turn back to virgin state.In this case, user's account can be automatically returned to guest's account.
If open OK button 913 in step 504, then CPU 101 determines that in step 506 password thitherto inputed is whether consistent with the user cipher in user's the user key file 310.If the two is inconsistent, then CPU 101 shows error message and is back to step 502 in step 507.If two password unanimities, CPU 101 closes password authentification screen 901 and stops described process in step 508.
The administrator's password checking of the step 419 of Fig. 4 b is handled with the processing of Fig. 5 a similar.Yet administrator's password shown in Fig. 9 b checking screen 902 shows in step 501.
Fig. 5 b preserves the process flow diagram of handling for the file that is provided with that file is set of the step 416 among Fig. 4 b.At first in step 511, the file that is provided with of CPU 101 displayed map 10a is preserved screen 1001.The check box that is used to specify the project that file (referring to Fig. 3) is set that will preserve is displayed on the screen 1001.For example, " system's setting " check box 1011 is selected, and " scene storer " check box 1012 is not selected, make system's configuration information of system configuration information memory block of current storage be stored in system's configuration information 332 that file 330 is set, and the information of scene storer 320 is not stored in the scene storer 334 that file 330 is set.The project that the user of login haves no right to preserve becomes ash.For example, " routine library A " check box 1013 becomes ash, and it indicates the user of current login to have no right save routine storehouse A.In the drawings, " 1014 " represent the OK button, and " 1015 " represent X button.
After step 511, CPU 101 determines whether to detect the operation of the check box of choosing/do not choose each in step 512.If detect the operation of the check box of choosing/do not choose an item, so CPU 101 make in step 513 this project the choosing of check box/selected state is not opposite.CPU 101 operates in step 514 test button then.If do not detect push-botton operation, then CPU 101 turns back to step 512.If open X button 1015, CPU 101 skips steps 515 and advance to step 516 then.If OK button 1014 is unlocked, then CPU 101 preserves the data of choice and advances to step 516 in file 330 is set.Will preserve the file 330 that is provided with of choice data specifies by the filename that is provided with in the user's of login the user key file 310.If in account set handling described later, newly write one the be provided with file of filename to replace being read when the user logins is set, then can use the file that is provided with that file is set rather than reads that newly writes to preserve file is set.
Though the process of Fig. 5 b that processing spec has been preserved in conduct, the file load that is provided with of the step 423 of Fig. 4 b is handled the above-mentioned process that is similar to.Yet, in loading processing, file load screen 1002 is set at step 511 displayed map 10b.The check box that is used to specify the project that file 330 is set that will load is displayed on the screen 1002.For example, the data with choice 1021 are loaded into current storage 303 grades from file 330 is set.The project (for example, project 1023) that the user of login haves no right to load becomes ash.In the drawings, " 1024 " represent the OK button, and " 1025 " represent X button.CPU 101 carry out to load in step 515 choice data processing and carry out the processing of the screen 1002 of closing Figure 10 b in step 516.
Not only in user login or when withdrawing from, and when the user clearly asks, can both execution graph 5b file preservation/loading processing is set.
Fig. 6 a is the process flow diagram that withdraws from the Action Events processing performed when the exit button 252 of Fig. 2 is unlocked.In step 601, CPU 101 shows that one withdraws from screen.Though not shown, withdrawed from screen display the inquiry information and the OK button that whether withdraw from.In step 602, CPU101 determines whether to detect push-botton operation.If X button is opened, then CPU 101 determines to withdraw from processing and has been cancelled and has stopped withdrawing from processing.If the OK button is unlocked, CPU has made in the data that file is set that step 603 determines whether to have read when the user of current login logins the state change has been set so.If made change, then CPU carries out in step 604 file preservation processing (referring to Fig. 5 b) is set.CPU activates the account of " guest " in step 605 then.In step 606, CPU determines whether the guest has the right to load file to be set and whether user key file 310 that filename writes the guest will be set with whether existing file to be set in the record storage (being flash memory 102 in this example) identical with storage user key file 310 according to guest's permissions data.If the guest has the right to load file be set, filename be set be written into, and to exist file is set, CPU carries out in step 607 and file load is set handles (referring to Fig. 5 b) and stop described process afterwards so.If the guest haves no right to load file be set, be provided with that filename is not written into or do not exist in flash memory 102 file is set, CPU does not carry out any other processing and stops described process so.
Fig. 6 b for when generation USB storage 110 remove incident the time performed processing process flow diagram.In step 611, whether the user that CPU 101 determines current logins is identical with the user that user key file by the USB storage that removes signs in in the frequency mixer.If be defined as not, then CPU stops described process.If be defined as is that then CPU determines whether to create or the compiles user key in step 612.If this is defined as, then the CPU USB storage of determining to be stored in the user key file 310 in the processing that is created or edited replaces the storer inserted and is newly inserted, and does not carry out any other processing then and stop described process.If in step 612 is not to create or the compiles user key file, then CPU determines that the user of current login has asked to withdraw from and activates guest's account in step 613, and shows in step 614 and to comprise the dialog box that message " withdraws from ".In step 615, CPU waits for that the OK button on dialog box is unlocked.If the OK button is unlocked, then CPU carries out and superincumbent step 606 and 607 identical processing with 617 in step 616, stops described process then.
Fig. 7 a is the process flow diagram that user key is created processing and user key account set handling.Herein, suppose to have shown active user shown in Figure 11 and user key management screen according to specific operation.
The screen 1101 of Figure 11 at first, is described.Account is provided with button 1111 and is used for issuing setting or changing password or filename is set and the instruction of active user's (that is the user of login) authority.Button 1112 preferably is set is used to issue the instruction of U preference data 314 that is provided with or changes active user's user key file 310.User-defined SW is provided with button 1113 and is used to issue the instruction of SW data 313 of U definition that is provided with or changes active user's user key file 310.User key is created the instruction that USB storage that button 1114 is used for being distributed on current connection is created new user's user key file 310.The user key account is provided with button 1115 and is used for issuing the instruction that the account that is provided with or changes the user key file 310 of the USB storage 110 of current connection or flash memory 102 is provided with data.User's switching push button 1116 is used to issue the instruction (i.e. login once more) of switching the active user.
Authority according to the active user allows or does not allow to show each button on screen 1101.Because button 1111 to 1113 is used to the data that the active user consults, is provided with or change is relevant with the active user, can show them at least.Yet, in some cases,, may not allow the active user to be provided with or change screen (for example, the screen shown in Figure 12) data that when opening these buttons, show though allow active user's data query.This equally also is genuine for user's switching push button 1116.When not allowing the active user to create new user key, button 1114 becomes ash.Similarly, when the account that does not allow the active user to be provided with and to change another user's user key file was provided with data, button 1115 became ash.
When being unlocked, carries out by the button 1114 on the screen 1101 of Figure 11 the processing of " user key establishment " Fig. 7 a afterwards.At first, the new user name that will create in step 701 input.In step 702, CPU 101 shows and corresponding to the user-dependent account of inputing user name screen (referring to Figure 12) is set.When " high authority user " created user key, the USB storage that CPU points out the user to remove current insertion at step 701 display message is inserted then will be to its USB storage that writes.In response to this message, the user removes that they are current to be inserted into the USB storage in the frequency mixer and to replace it to insert the USB storage that will store the user key file of new establishment.This removes or inserts and can't start withdrawing from or login process of above-mentioned steps 411 or 612.High authority user can only create general user and can not create new high authority user.
Figure 12 a and 12b represent that account is provided with the example of screen 1201.Account is provided with screen 1201 and comprises two Tab keys 1210 and 1220.Can the authority that relative users is set on the screen be set in the authority of Figure 12 a that shows by selection Tab key 1210.Can be provided with at the password by selecting Figure 12 b that Tab key 1220 shows and other and be provided with on screen and change password or filename is set.
High authority user is provided with the authority that button 1202 is displayed on Figure 12 a and is provided with on the screen.If this button is opened, then the user just becomes high authority user, and if close it, then the user just becomes the general user.Have only " keeper " the high authority user of opening/closing that has the right that button 1202 is set, and other users can not action button 1202 (that is, button 1202 becomes ash for other users).Reference number " 1211 " to " 1215 " representative is used to be provided with the project of user right.For example, the project " user is provided with preservation " in the middle of the project 1211 relevant with information-setting by user is set as " zero ", makes the user be allowed to save the data in the user key file 310.The authority items that is set to " * " is not allowed to for the user.Authority according to the user who carries out the login that the account is provided with allows or does not allow switching between " zero " and " * ".That is the project implementation setting that can not have no right to them of high authority user.
