people do not have a router around, in fact, you can also use a network cable to the Raspberry Pi and computer directly connected. The above two methods are to find the IP address of the Raspberry Pi, with advanced ipscanner tool scanning (own network up and down bar), the specific reference I give the tutorial link,

6. Synths (synthesizer)
The synthesizer enables the play method to make different sound effects. The default synthesizer is "pretty_bell", but you can change it by yourself:
"pretty_bell""dull_bell""beep""saw_beep""fm"
Try different synthesizer:
