Thanks to Larry Troxler and Arjen Van Der Schoot for their great
descriptions of granular synthesis for us newbies and non-ee/dsp folks:

Arjen Van Der Schoot replied to the granular synthesis question
with the following quotes and advice:

I can paste three explanations of the authorities:

     All sound is an integration of grains, of elementary sonic particles,
     of sonic quanta. All sound, even continuous musical variation,
     is conceived as an assemblage of a large number of elementary sounds
     adequately disposed in time. (Yannis Xenakis)


     Granular synthesis of sounds involves generating thousands of very
short sonic
     grains to form larger acoustic events. Granular synthesis is a
fruitful technique
     for the exploration of a different class of computer-generated sound
spectra
     than those produced by additive, subtractive, or modulation
techniques.  (Curtis Roads)


     Granular synthesis is a sound synthesis model based on the assumption
     that sound can be considered as a sequence, possibly with overlaps,
     of elementary acoustic elements called grains.
     Granular synthesis constructs complex and dynamic acoustic events
     starting from a large quantity of grains . (Giovanni de Poli)

Also, go get Thonk, free granular synthesis for the Mac,  at
www.futuremusic.nl/AudioEase...

Larry Troxler drew a great graphic which shows how granular synthesis works:

My (Troxler's) def of granular: picture a grain as taking a chunk of sound
that is
about 20ms long, give or take. At this duration, it's somewhere in the
ambiguous area where it's maybe just long enough to give a sense of
pitch, but short enough so that's it's just a snapshot of sound. Imagine
extracting a bunch of these grains from a various points within sound
sample. Then you "resprinkle" your audio space with these grains, but
starting at all different times, and some of them may be stretched or
shrunk with respect to the original. Sort of like this:

Original sound sample:

time -->
|--1--|  |--2--| |--6--| 
  |-3-| |-4-| |-5-|      

Synthesized output:
time -->
|--1--| |--1--| |--6--| |--6--| |--2--| |--6--|
 |--2--| |--2--| |--2--| |--2--| |--6--| |--2--|
|----3------| |-------3------| |-----4-------|


Much Thanks to Larry and Arjen for the straight talk for newbies
and signal processing novices!

and rewrite it in a more compact (more Cybilized)
fashion?

The problem is that the instrument plays 7 notes
of different duration simultaneously.

Anybody else get this?

I noticed the same thing. Maybe some subscriber email address has
changed or removed without unsubscribing the Csound mailing list.
