Glad to hear it's working better.

UGens shouldn't be asking for a "buffer.index" -- a Buffer object knows how
to report its bufnum, not an index.

You need to change this to Out.ar(0, sig) -- DO NOT DO [0, 1] here.

Try this to see why:

s.boot;

s.scope(3);

a = { Out.ar([0, 1], [SinOsc.ar(880, 0, 0.1), Saw.ar(440, 0.1)]) }.play;

amp = 0.1 to save your ears. You can use the right-hand slider to scale the
display up.

Bus 0 = sine. OK.
Bus 1 = sine + saw. Nope.
Bus 2 = saw (+ hardware input, if you have the default two hardware output
channels)

I'm quite sure this is not what you wanted.

As I had said before, if you find yourself getting in the habit of writing
"Out.ar([0, 1]...)," better to get out of that habit right now. It's not
correct usage.
