Juhana is worried because he thinks that if we write our free,
disk-based soft-sampler Nemesystech will sue us.
:-)
Anyway disk buffering schemes are as old as ENIACS :-)
I don't think Nemesystech will sue use because
we are writing software which issues an
mlock() call to keep the initial portion of the sample in memory,
mmap()s the rest into mem, and streams the data to a lock-free
ringbuffer ( Paul, lockfree is cool, isn't it ? :-) ) do a dsp thread.
again , when I get some time, I will write my usual hack to provide
a working proof of concept. :-)
Benno.
