Won't update outputs from the second run

What steps will reproduce the problem?
1. run the following code under an action-coding environment
require 'funnel'
include Funnel

R = 11
G = 18
B = 19

def setup
  size 360, 480

  config = Fio.FIRMATA
  config.set_digital_pin_mode(3, PWM)
  config.set_digital_pin_mode(10, PWM)
  config.set_digital_pin_mode(11, PWM)
  @nodes = [1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12]
  @fio = Fio.new :applet => self, :config => config, :nodes => @nodes
  @osc = Osc.new Osc::SIN, 0.5, 0

  @fio.io_module(ALL).port(G).filters = [@osc]
  @osc.start
end

What is the expected output? What do you see instead?
Works fine at first run, but won't update outputs from the 2nd run
