Actually - while the .app said 0KB, I can navigate and see contents in =
Terminal :/ - I was able to open SC from command line.
Scott - can you try the example below to see if it works / doesn=E2=80=99t=
work for you, please?
SynthDef(\test, {
Out.ar(0, SinOsc.ar(440, 0, 0.2));
}).add
// doesn't ever schedule
s.sendBundle(0.1, [\s_new, \test, 1000, 0, 1] )
// works
s.sendBundle(nil, [\s_new, \test, 1001, 0, 1] )
