Many thanks sirenia!

Those lovely blipping effects lol come from an ancient softsynth from 1996 called "Simsynth" (http://www.threechords.com/hammerhead/simsynth.shtml  ) ; I just recorded a few blips in *.wav format and imported them in Cubase SX adding them to the track.

I love to play with synths but I sweat blood when I have to create complete song! :-)))
