     FIGS. 8A to 8D are flow charts showing the outline of the music editor function. This program starts when the music editor icon on the main menu is touched. 
     At step S1, an editor display shown in FIG. 4 is given. At step S3 it is checked if one of the channel number change keys 45 is touched. If touched, at step S4 the channel number is incremented or decremented by 1 according to the touched key. At steps S5 and S6 if a key signature icon is touched, the touched key signature is selected and stored together with the musical note information. At steps S7 and S8, a time is set with a time icon, and at steps S9 and S10 a tempo is set with a tempo icon. 
     At steps S11 and S12 the volume of a musical tone is set with a volume icon. At steps S13 and S14 the musical instrument type is set with a musical instrument icon 47. At steps S15 and S16, the rhythm is set. 
     At steps S17 and S18, when one of the octave setting keys 46 is touched, the octave number is incremented or decremented by 1 according to the touched key. At steps S19 and S20 a tone time icon is touched to select a note such as a crotchet, quaver or the like. At step S21 if the keyboard 44 is touched, the flow advances to step S22 whereat tone information corresponding to the touched key position is inputted. 
     At steps S23 and S24, when a rest icon is touched, the touched rest is inputted. At steps S25 and S26, when an eraser icon is touched, a note on the musical score indicated by a cursor 48 is erased. At steps S27 and S35 it is possible to compose music as desired using the icons such as those crescendos, decrescendos, slurs and the like. 
     When a play icon is touched at step S36, a display as shown in FIG. 5 is obtained at step S37. In this case, if the musical instrument icon is touched at step S38, it is designated at step S39 if a channel play is to be executed or not, with the result that the musical instrument and channel number concerned are displayed dark. If the start switch 50 is touched at step S40, playing music starts at step S41, or restarts after interruption. Interruption of playing music is effected at steps S44 and S45, whereas the stopping of the playing of music is effected at steps S44 and S45. 
     When an editor screen call icon 48 is touched at step S47, an image of the folder 11 is displayed at step S48 so that the user touches a desired data sheet to read it. The read-out music data are stored in the music data area 81 in the RAM. When the storage icon 43 is touched at step S49, an image of the holder 11 is displayed at step S50 so that the user touches a desired data sheet to store it therein. 
     Step S51 and the following steps illustrate the flow chart for performing the tool box function. This tool box function can be read and executed for other functions when the tool box icon is touched. 
     If the icon 41 or 42 is touched at step S51, a tool box is displayed at step S52. If a block-pick-up icon is touched, the flow advances to step S54 whereat the musical tone information designated is block-picked up. If an attachment icon is touched at step S55, the flow advances to step S56 whereat the already block-picked-up musical tone information is attached (stored) at from the cursor 48. 
     It is checked at step S57 if an external block-pick-up switch is touched. If the external block-pick-up is designated, the flow advances to step S58 whereat the musical tone information within the designated block is block picked-up to the external. The block-picked-up musical information is stored in the work area of the memory so that the information can be read and attached to the tool box function, and used for example as a telephone holding sound in the telephone function. The tool box function terminates when an end icon is touched. 
     As seen from the foregoing description of the embodiment, the information processing apparatus has a plurality of functions which can be selectively executed as desired. For instance, music data produced with the music editor function can be used with other functions such as a telephone function, an alarm function and the like.
