EventPattern playing at about half speed

Discussed in #360
Running the code below I expect it to generate 4 notes in series, each a second long as set by the delta and duration keys , however they are each about 2 secs long.
@synthdef()
def test(gate=1,freq=440):
env=Linen.kr(gate,0.01,1.0,0.01,done_action=DoneAction.FREE_SYNTH)
osc=SinOsc.ar(frequency=freq)
out=env*osc
Out.ar(bus=0,source=out)
pattern=EventPattern(
freq=SequencePattern([440,880],2),
delta=1,
duration=1,
synthdef=test)

Timing's not quite the same as with SuperCollider.
1.0 duration is a whole note.
The default clock (Clock.default()
will get it for you) defaults to 120BPM. That's 2 beats per second, making 4 beats (4/4) take 2 seconds.

If you don't want to adjust your durations and deltas, you can just bump the tempo on the clock.
Clock.default.change(beats_per_minute=240)
probably gets you the tempo you want.

ah ok, that makes sense. many thanks
oh, and that should be brackets after default ie Clock.default().change(beats_per_minute=240)
