Can someone take a look over this UDO and tell me if it will actually
do what I want, which is to split an interleaved audio intput into
left and right? Instrument below...

opcode interleaveItAlone, aa, ai
setksmps 1
kcnt init 0
ain, ichannels xin
aLeft init 0
aRight init 0
if(ichannels==1) then
aLeft = ain
aRight = ain
elseif(ichannels==2) then
aLeft = (kcnt==0 ? ain : aLeft)
aRight = (kcnt==1 ? ain : aLeft)
kcnt = (kcnt==1 ? 0 : kcnt+1)
endif
xout aLeft, aRight
endop


instr 1
a1 chnget "sound"
aLeft, aRight interleaveItAlone a1, 2
outs a1, a1
endin

Because I'm sending an entire stereo audio stream over a single mono
channel. My frontend loads a sound file and then pipes it to Csound on
a single audio channel. Perhaps it is unnecessary or?

Whoops, I missed that! In the end I think maybe it's better that I
give users the option of retrieving the channels separately rather
than messing with UDOs.

It was with you in mind that I was trying this out! I was thinking
that it might be nice to stream a files in Cabbage directly to an
instance of Csound. Check out the attached screenshot. The nice thing
is users can load a sound file of any type and stream it directly
across to Csound without having to worry about what format it's in. I
still have to add some funk to it, but it's almost there now. I think
accessing each individual channel is cleaner than worrying about an
interleaved stream.

So I did :0

They always could. I hardly bother with a host at all. I know lots of
people prefer to use a host, but I've never really ever used one so it
seems a step too far for me when I can just use Csound! Btw, if you
copy and rename the Cabbage binary to the same name as your csd file
it will open in a special 'standalone' mode when users launch it
(although this is untested on OSX). Check out the screenshot of a
sampler I'm working on.

This is true. Automation is something most hosts do particularly well.
It's hard to compete with, but I'll keep trying.

This could be taken care of by using function tables to create
automation curves no? Using Cabbage or CsoundQT you could just pick a
pattern or curve from a dropdown list and have the table recreated on
the fly. I guess you would still need a quick and dirty way of
creating rough envelopes. This is much needed.
