midi error syntax issues

hello
i struggling trying finalise code working on. using ping sensor trigger different midi notes depending on proximity (3 notes in total) , although method using seems work in other midi enabled arduino code have used reason 1 keep getting following error message:


in function 'void loop()':
error: 'midiout' not declared in scope

i have used method of midiout , stuck doing wrong time around. suggestions?

code: [select]

/* new variables */
int delay_time = 30; // delay amount each write cycle.
byte channel = 1;

byte printing_byte = 0;

/* ultrasound sensor

*
* reads values (00014-01199) ultrasound sensor (3m sensor)
