[comp.sys.atari.st] The ADAP sound rack

dmb@TIS.COM (David M. Baggett) (04/14/88)

Bill Rosenkranz mentioned sampling keyboards.

Bill:  What about the ADAP sound rack?  Isn't that a 16-bit sampler?  I
       thought they were about $2K -- competitive with the 12-bit 
       samplers if you have a good controller keyboard.

   There's a strore here in Maryland called the Guitar Exchange which 
sells keyboards (as well as guitars and everything else musical).  I was
down there about a month ago and saw the ADAP rack, controlled by
guess what, an ST!  They have a mac too...
   The guy gave me a demonstration of the E-mu II (another sampling
keyboard).  Basically, he had "obtained" samples from "Owner of a
Lonely Heart" and was playing the song entirely with the keyboard
(it actually sounded like the recording) and mentioned that Yes actually
used exactly this method to produce most of 90125.
   Aren't samplers neat?

Sampling keyboards and rack-mount units are not just neat. A sampler
takes any sound and stores it digitally for later replay (that's the
simplified version, since most good samplers let you edit the sound
after it has been 'sampled').

Sampling drum machines can incorporate percussive sounds like a drum,
for instance the human voice screaming "Oi!" or the sound of breaking
glass. Once digitally stored, the sound can be replayed from a computer
(in fact most samplers involve the use of a computer). The sounds in
Dungeon Master and Gauntlet for the Atari ST were done this way.

A CD player, by the way, is a sort of high memory sampler. The data is
read from the disc instead of RAM.

Hmmm... Why did I write this? I dunno... Maybe it'll help some of you to
understand samplers and sound digitizing...
