Interesting and cool thread, and mrmoonlight you are my hero of the day! Loved that video haha!
On the subject I'd like to add: Never underestimate the obsolete!
Another perspective I tend to have in my head is that the Amiga is the "turntable of computers" - You don't have the in built sound source, you submit to intriguing limitations, and from there you can take anything and do everything.. be an inventive turntablist or producer =)
The most obscure professional music I've come across yet who made their mark using an Amiga is the Nasenbluten (nosebleed) group from New Zealand.. More 'mainstream' and familiar name for house/techno lovers might be Jori Hulkkonen from Finland.
What I do think helped the miggy a lot was its quick evolving 'breeding ground for the underground' - the demoscene, continuing from c64 amateurs keep hacking away, exploring, inventing, and cultivating each other so to speak. Karsten Obarski and the following tracker developers launched many a professional career in music (on many levels), for kids who got caught up in this popular activity of tracking their musical ideas or first experiments =)
The action and interesting stuff going on creatively in the amiga scene accellerated so fast in the early nineties.. as bloodline said so well, the creativity that comes with ignorance =D
For a kid it wasn't about being professional, but getting creative and becoming better at it.. so on a long term I'd say Amiga had much more impact than Atari, BUT in the end everything kinda comes together as you can say you were inspired by Mike Oldfield using an Atari but you were using an Amiga yourself for expressing it..
Anyways, personally I've come to the conclusion that I got one instrument I know well enough, and that's Protracker. Been doing a sort of a 'comeback' to digital music the recent couple of years, and checking out one of these obese DAWs - still there's no way I can write music the way ProTracker lets me express myself - so to speak. With its old look and feel and technique and trickery involved its like that one guitar you never really heard the likes of anytime since.. Some songs just couldn't have happened if they weren't done with that instrument, you know? =)
Well, that was just from my (scene)point of view. Have a good day!
