'Yep, it is possible.

'To retreive the position you could use this function, (you need to
'paste the code into your program, code not working without proper MCI-
'declarations etc...)

'----------- start code -----------
     DECLARE FUNCTION Elapsed AS STRING
     DIM L AS STRING
     L = SPACE$(30)
     DIM Mins AS INTEGER
     DIM Sec AS INTEGER
     DIM QueryStr AS STRING
     QueryStr = SPACE$(30)

     FUNCTION Elapsed()
      mciSendString("set music time format ms", "", 0, 0)
      mciSendString("Status music position",VARPTR(QueryStr),30,0)

      sec = ROUND(VAL(MID$(QueryStr, 1, LEN(QueryStr))) / 1000)

      IF sec < 60 THEN Elapsed = "00:" & RIGHT$("0"+STR$(Sec),2)

      IF sec > 59 THEN
       mins = INT(sec / 60)
       sec = sec - (mins * 60)
       Elapsed = RIGHT$("0"+STR$(Mins),2) & ":" & RIGHT$("0"+STR$(Sec),2)
      END IF
     END FUNCTION
'-------------- end code ----------------

'The code above you use in case you send the complete file not parsed
'to the MCI (the MCI functions as the sequencer). In case you parse
'the whole file, you know the time from you timerfunction.

'And it is also possible to send a single message, like controllers,
'and note on and note off messages etc... You may try following code,
'just copy and paste into your code-editor and run:
