I
love Muslimgauze, used to be on the subscription series back in the day and have
lots of his stuff. In fact I have more Muslimgauze cds than Legendary Pink Dots cds and I have
nearly all of their stuff so that's saying something. Dude was
prolific.
Anyway, he definitely didn't use a computer DAW. Samplers, I don't know he always claimed not to. He didn't seem to use them in a very advanced way if he did, just chopped up loops, so it could all be tape like he claimed. As for the one photo of him with a rack of samplers in the bg, I doubt it was taken in his home studio. In the early days, for the releases on Extreme, he was recording and mixing in rented studios. He ditched all that and became home studio based around '93, when the Soleilmoon/Staalplaat releases started pouring out. You can hear a change in the sound and style. The Extreme stuff was lush and professionally engineered, and the Soleilmoon/Staalplaat releases sound thin and crunchy at first as he figures out how to mix himself. I don't think that photo was taken in his home studio simply because he was such a recluse.
Pretty sure he was mixing straight into the ADAT on the later stuff and the extreme distortion on several releases is from deliberately clipping the ADAT.
YouTube clips don't convey it but those later releases are the LOUDEST CDS YOU HAVE EVER HEARD, it's insane. There will be the quietest little synth gurgle or Arabic voice and then MASSIVE DISTORTED TABLAS blow out your speakers. The loudness wars are over, man, and Bryan Jones won. And he was already dead.
