Fairlight-CMI

Steve,

It isn't just the tracking filters. The CMI's used a
variable samplerate, with a huge range. There isn't
any digital sample interpolation happening. Was it 7
octaves of shift possible? I don't remember If you
upshifted the sample you can get harmonics that are
higher than in the original sample rates 1/2 of the
input filter cut off frequency. Much Higher.

A digital version of playing an audio tape faster or
slower.

Other samplers, like Roland, used a fixed sample rate,
with only a 2 octave shift range.  
The method of digital sample interpolation with a
fixed sample rate also makes a huge difference, and
will contribute a lot to the resultant sound, but in
all cases you never got any harmonics above the
original sample filter cutoff...

But, it was just a cooler bunch of people that made
it..
