This was not the case in sc 3.6. Shouldn't 'out' default to zero somewhere ?

[miguel-negrao]

Also,

Ndef(\x, { SinOsc.ar([200,500]) * 0.1 }).play(0,2)

plays both channels to channel 0:

NODE TREE Group 0
   1 group
      1000 group
         1001 temp__0x_0
           gate: 1 fadeTime: 0.019999999552965 out: 4
      1002 group
         1003 system_link_audio_1
           doneAction: 2 out: 0 in: 4 vol: 1 level: 1 lag: 0.050000000745058 gate: 1 fadeTime: 0.019999999552965
         1004 system_link_audio_1
           doneAction: 2 out: 0 in: 5 vol: 1 level: 1 lag: 0.050000000745058 gate: 1 fadeTime: 0.019999999552965

Isn't it supposed to play a stereo output to output channels 0 and 1 ? From memory I think that's how it was working in 3.6...

[telephon]

definitely it should …

The OSC message looks OK:

[ "#bundle", 15503069409855398668, 
  [ 21, 1002, 1, 1 ],
  [ 9, "system_link_audio_1", 1003, 1, 1002, "out", 0, "in", 4, "level", 1, "fadeTime", 0.02, "vol", 1 ],
  [ 9, "system_link_audio_1", 1004, 1, 1002, "out", 1, "in", 5, "level", 1, "fadeTime", 0.02, "vol", 1 ]
]

Coincidentally enough, I've just encountered an issue (recent git) where sclang appears to be sending the right OSC messages to create synths, but the controls end up with default values. Reported on the mailing list.

It may very well be the same thing.

Wasn't there some re-factoring recently of synth control initialization?

[telephon]

Yes, it was, I've reverted the corresponding merge in b629767
