Description
I've found this old music sheet in the attic, but I cannot read it. An old letter said that a secret message can be found by following the music. Can you help me?
Hint: this challenge does not use the regular flag format.

How the challenge works:
The music sheet contains Morse code. 1/4th of a note is the long stroke and 1/8th of a note is the small stroke of morse code. Between every letter there are either short or long rests. If a measure contains a full rest of 4 notes long, it means that it has reached the end of a sentence. The following sentences can be translated from the music sheet:
Wij zijn de computerzonen Wij zijn van de infogroep Macintosh of PCklonen Zijn voor ons het beste snoep Ei het lied der Vlaamse hackers En der Vlaamse pintepakkers En met oude bit en byte Gamen wij all day all night The flag is we l4ve mus1c
--> There is no format for this challenge. The answer is "wel4vemus1c".
