Could you describe, what the pedal controller does in fluidsynth?
I mean the "normal" sustain pedal, like on a piano.
But I just found the mistake: the sequence of the numbers in your fluid.pd help-patch is false:
you did it this way:
[ ctlin ]
| | |
[ pack 0 0 0 ] | [ cc $3 $1 $2(
but it should be:
[ ctlin ]
| | |
[ pack 0 0 0 ] | [ cc $3 $2 $1(
Now it works fine!
