Okay, so I realize that this has been extensively talked about, and a lot of people have their own theories on the matter. It is quite possible, and more than likely, that I am 100% totally wrong here, but to me it makes sense. I think that the "secret weapon" is really just a Roland SH-101, and not a magical box that is all mystical and secretive. Maybe it started as kind of a silly joke, because they used it a lot or something. I have had this theory for quite a few years. It was developed some time ago after wondering what this "secret weapon" might possibly be. Was it a sampler? Was it a homemade piece of equipment that spits out weird sounds? Maybe it was an unusual process in their audio chain that they use? I have since then, settled on the idea that it is in fact a synth.
"1988: michael bought what he now describes as the band's "secret weapon" synth from a friend for £100 whilst travelling on a bus."
I read that quote a few years back and thought yes! it's IS a synth. Now, what fairly inexpensive synth could it be?
So I went on a listening search, and time after time I could hear one synth in particular popping up in most of their songs. I can quite clearly hear what I believe to be an SH-101 in XYZ, SAC, M9, Triangles & Rhombuses, Sixtyten, Kaini Industries, Bocuma, Roygbiv, Olson, Pete Standing Alone, Happy Cycling, Everything You Do Is A Balloon, June 9th, Mellissa Juice, etc. the list goes on. It is alos obviously in a lot of their earlier work, and I believe it even appears quite a bit on Geogaddi, though possibly sampled, and layered so it's quite a bit harder to pick out.
Anyway, this might be a totally useless thread, but I'd like to hear your opinions on this matter...
