Global triggers not working

[brianhouse]

t.trigger form works well, but naked trigger does not perform as expected

measures = [    [[K, K, K, K], 2],
                [[H, H, H, H], 1],
                [[S, S, S, S], 3]
                ]

t = Thread(10)
t.add('measure')

def advance():
    next_measure = t.measure % len(measures)
    t.pattern, cycles = measures[next_measure]
    trigger(advance, cycles)
    t.measure += 1


trigger(advance, 0)
