yeah, we know!  :-)

interesting problem, new technology comes along, making huge improvements
in some ways and obsoleting the old stuff. But there's usually some
characteristic of the old stuff that becomes very difficult in the new
technology. And then you need a few more generations of new technology
before you are able to do the old idea again. In this case, you used to be
able to easily change the sample clock on A/D and D/A convertors, and they
would be happy and nothing else in a simple delay system would get screwed
up. Nowadays, the convertors give better audio but don't let you do that
sample clock trick anymore, and other things in the system that need
accurate timing (like midi) get screwed up. So for the echoplex and jamman,
this sort of thing is impossible. So now you need to add a fair amount of
dsp processing and more sophisticated real-time os techniques to be able to
do what once just required a very cheap part. such is progress....
