Hoover synth strange behavior

[windo]

It seems like :hoover escapes my :lpf fx somehow (running sonic-pi from latest git):

live_loop :baseline do
  use_synth :hoover
  with_fx :lpf, cutoff: :c4 do
    play :c3, attack: 0, release: 0, sustain: 4
    sleep 4
  end
end

For the first iteration of the loop :hoover is not limited by :lpf but it is applied for the following iterations of the loop. When I want to change the loop definition (ex: the cutoff) then after the change, the next iteration bypasses the :lpf again.

I did some experiments on other FX. All xpf and eq FX are definitely affected. Seems like bitcrush, distortion, krush, reverb and flanger are not as obviously affected.

The most interesting effect was for pitch_shift - it sounded like the first iteration of the loop was playing both the dry and wet signal at the same time (both pitch shifted and orginial sound). Maybe that could be a clue as to what's happening?

But writing this, I now listened to some of them more carefully and I think all of them are affected the same way - it is just harder to tell for some of the effects. Pitch chang effects are tthe most striking when dry and wet signal are juxtaposed.

@windo - sounds like it could be the same issue I noticed in #1794 !

Yep, I think it is a duplicate indeed!
