Hi Robert,

Sorry that my reply is so late, but I've just returned from vacation and am
just now catching up on my email...

It's good to hear from you.  I'm really looking forward to checking out
your DJ application when you have something ready to show.  It's
interesting to see that you're looking into support for a separate
headphone cueing bus.  I can see that you're ready to make a *real* DJ app!

Gabriel is right in suggesting that the AudioChannelMerger could be used
for this.  In this case, you would feed two stereo inputs into the merger
and get a four-channel output.  But the multi-channel implementation is
currently incomplete, so it's not *yet* possible to try this right now.
 I'm planning on working on this after I finish the
MediaElementAudioSourceNode (for streaming application with <audio>).  I
hope we can keep in touch about progress on this, and that you're able to
get to work on other aspects of your application in the meantime.
