Well, I guessed this would only interest a few of you guy's so I'm not to surprised in the lack of response, perhaps If I asked more specific questions that might help.
What kind of waveform do you think would have been used here?
What kind of filter, a low pass? or something more like a vowel filter maybe?
An interesting thing I noticed about this sound is that the pitch of the waveform is dropping slowly whilst the filter is opening slowly, it's a really nice technique I've heard used a lot receantly. can this be done easliy on a Virus, I see that there are seperate envelopes for pitch and filter but can the attack and decay of these envelopes be matched to such a shallow slope?
Anyone?
EDD: I've zipped a smaller edit of the track here
DJ Marky - Riff Raff - Part_1.zip - 3.61MB incase that helps?
