Um... Kraftwerk doesn't sit there and edit the BIOS during his performances, nor does he tweak any multipliers, ETC... nor does he do anything to the computer itself besides utilize it to run the PROGRAMS he uses on the computer. The computer itself simply allows the instrumental programs to run, besides other things. Without instrumental software, including the software even allowing it to process sound.. called an audio driver, which even audio hardware is dependent on, the computer only has the following sounds: Beep (one for an all good after the P.O.S.T.) and further, a sequence of beeps indicating certain failures after P.O.S.T. and this happens IF you have an onboard PCM speaker that exists solely for the purpose of post beeps.
What I'm saying is that the computer itself is still not the sole proprietor of musical expression. You still need software. You still need the proper hardware that is NOT considered a computer, but merely components, you still need the software that the hardware requires, and you finally need the software that's actually programmed to create sounds and arrange them in a musical fashion.
I guarantee you, without all those things, a computer is still a computer... but it is nowhere near an instrument unless you're using it as a junk piece of plastic for your replacement effect drum or what have you.
