This never ending randomly generated song is just a 10kb xrns file version1: http://www.wikiupload.com/6BIL2VDFP8UH0B1 version 2: http://www.wikiupload.com/CU2BSL5RH9KRU30
No samples, no vst/vsti’s, no notes, just weird music. 
didn’t know the ver. n° 2 ! thanx !
SHOULD BE FEATURED AS A DEMOSONG IN THE NEXT RENOISE RELEASE
nice one! amongst the demosongs there is already an example of this techinque anyway (Neurotix-Nivi.xrns)
Thanks KURTZ and It-Alien! 
Not to argue, but the only similarity i see with Neurotix-Nivi is that i have offset a flat signal from line input to get sound. Other than that the tracks are completely different. I haven’t used a single pattern effect or any form of sequencing, it has no beginning or end and it’s a bit different each time you play it.
I don’t claim to have invented this technique though (d-blue was the one that got me onto these projects with his ringmod tone generator) and about it being a demo a Renoise noob probably wouldn’t learn anything useful from it anyway. 
It seems like i have mixed up the versions, because they should be more different to each other than it seems now, hope i haven’t saved over the other version, i’ll have a look and see if i can find it.
