Hi,

I'm going to write a low latency output plugin for a software synth
program called Buzz (www.buzzmachines.com), and I want to use kernel
streaming to do it.  Would it be easier to use the ksProxy filter or to
use IOCTLs?  Using the ksProxy filter, how can you pass audio data from
a program into the filter graph?  The MSDN Library seems to only cover
creating filter graphs, but it doesn't tell you how you can pass audio
data to a filter's input pin from a program.  Is it possible to do this?
If so, how?
