parallel synth graph problem #39

Closed telephon closed 6 years ago

telephon commented 6 years ago

It seems we have to really carefully test this new implementation.

There is a subtle error here:

t = Steno.push(2);
t.quelle(\i, { Impulse.ar(3) });
t.filter(\f, { |in, controls| RLPF.ar(in, Rand(4000, 8000), 0.01) });
t.filter(\d, { |in, controls| DelayL.ar(in, 0.2, SinOsc.kr(0.3, Rand(0, 2pi)).range(0, 0.2)) });

// all these are ok
-- i
-- if
-- if if
-- i[f f]
-- i[f f]d
-- i[f df]
-- i[f fd]

// but these are wrong (both signals go through the same delay)
-- i[fd fd]
-- i[(fd)(fd)]

The structure is this (correct):

------------  i  ------------
0
0
------------  [  ------------
nil
nil
------------  (  ------------
0
      2
------------  f  ------------
      2
      2
------------  d  ------------
      2
      2
------------  )  ------------
      2
   1
------------  (  ------------
0
      2
------------  f  ------------
      2
      2
------------  d  ------------
      2
      2
------------  )  ------------
      2
   1
------------  ]  ------------
   1
0

but somehow the signal flow doesn't follow it correctly.

The issue still is there, now we have silence for the problematic case …
