Nah, they've disowned audio, or at least all of the competent audio
folks that worked there.

From a quick reading, as long as you avoid a "plurality of cells" you won't
infringe ;-). In fact, it looks like the innovation that they are claiming
is
to apply their algorithm only to a plurality of cells, not a majority or
even
all of them. Whatever a "stream cell" is.
I would not let this patent stop me from trying to develop an open source
sampler. There's more than one way to do it. Just avoid a stream engine
and your safe. Call it a "sample engine" instead.
Just about everything in the continuation has been standard practice for
so long that I'm (not really) surprised that the PTO accepted all of the
claims.
