So L = sin(440, 0) + sin(441, pi) and R = sin(440, pi) + sin(441, 0)

SynthDef("x", {
    Out.ar(0, [
        SinOsc.ar([440, 441], [0, pi]),
        SinOsc.ar([440, 441], [pi, 0])
    ].flop)  // <<-- flop the 2d array here
}).dumpUGens

[ 0_SinOsc, audio, [ 440, 0 ] ]
[ 1_SinOsc, audio, [ 441, 3.1415926535898 ] ]
[ 2_Out, audio, [ 0, 0_SinOsc, 1_SinOsc ] ]
[ 3_SinOsc, audio, [ 440, 3.1415926535898 ] ]
[ 4_SinOsc, audio, [ 441, 0 ] ]

That's the droid you're looking for.
