Just a little tangential comment about "where [one] puts [one's]
grains": I've generally found that the number of grain streams and
the number of speakers - as there are more speakers I tend to need to
increase the number of streams to create what seems like an
"equivalent" (mutatis mutandis) effect...
Yours truly,
David
