Re: [Bluemusic-users] More than two output channels

[Steven Yi <ste...@gm...>]

Hi Dave and Erik,

Thanks for chiming in.  I was reviewing things to implement but was
having a hard time figuring out what to work on next.  Getting things
that have pressing needs makes it a lot easier. :)  I'll start taking
a look tomorrow at what is required to get this implemented.  I think
it will probably take 2-3 days to implement.

Question: When generating the output, should the output be done up
until the last score for the item being output, or always to the
length of the original full score, even if there's a lot of silence? I
am thinking it should be fine to generate until length of score for
that item, so the exported wave files could end up with different
lengths.  I'm indifferent in some ways as I do all my mixing in blue.
:P

Thanks!
steven
