It's not like they bought VCRs at BestBuy and stuck a different ROM in it.
They just use commonly available off the shelf components and designed
into their fully custom system level hardware, which is what everybody
in just about all electronic products. Whether it is a VCR transport or an
audio IC it is the same concept. Nobody is designing their own custom
or anything like that.

that would mean re-writing all software for a different processor and
system, which would be far more complicated and expensive than designing
new hardware to match the 10 years worth of software development we've

That is a big part of the hardware. Plus a lot of special audio circuits
for specific routing needs of looping, designed to pro-audio standards.
Special sync circuits, etc. Very quickly you would be wondering, "why are
we spending such tremendous effor to customize this existing board that
hardly does anything we need to begin with? It would just be easier to
build our own hardware from scratch." and you would be 100% correct.

it would actually cost you far more. you would be into several hundred
dollars just on these off the shelf pc parts, before you even got to the
custom electronics, custom chassis, controls etc. A lot of that money
be spent on stuff that would be completely useless in the application.
remember, you can't use the cheap stuff because people demand better
quality standards than what most PC hardware is designed to.
>After all, it's the software that primarily makes a looper.
yes and no. It is the software plus the user interface. In the case of a
musical instrument that you play, much of the user interface is hardware.
The better this interface matches the way the user wants to control the
specific application and the environment they use it in, the better the
experience. General purpose hardware interfaces can never be as usable for
a given application as a custom designed one. Would you rather control
sounds in a performance with an actual drum-like device as the interface,
or by tapping keys on a notebook?
