Re: [Sndobj-devel] Mixing objects

[Victor L. <vic...@nu...>]

Something like this:

mix1 = Mixer()
mix2 = Mixer()
osc1 = Oscili(...)
osc2 = Oscili(...)
echo = Comb(0.5, 0.5, mix1)

mix1.AddObj(osc1)
mix1.AddObj(osc2)
mix2.AddObj(mix1)
mix2.AddObj(echo)

t = SndThread()
t.AddObj(osc1)
t.AddObj(osc2)
t.AddObj(mix1)
t.AddObj(echo)
t.AddObj(mix2)

outp = SndRTIO(mix2)

t.AddObj(mix2, SNDIO_OUT)

t.ProcOn()

etc...
