Tutorial 13: Advanced Clock

To see what is scheduled to be played.

print(Clock)

To see what the latency is

print(Clock.latency)

The clock can schedule anything with a __call__ method using It takes an absolute time clue to schedule a functions Clock.schedule needs to know the beat to call something on

Clock.schedule()   # raises TypeError

Schedule an event after a certain durations Clock.future needs to know how many beats ahead to call something

Clock.future()     # raises TypeError

These are equivalent

Clock.schedule(lambda: print("hello"), Clock.now() + 4)
Clock.future(4, lambda: print("hello"))

To schedule something else

Clock.schedule(lambda: print("hello "))

We can call something every n beats

Clock.every(4, lambda: print("hello"))

Get the current clock and add 2. Useful for scheduling.

print(Clock.now() + 2)

Issue command on the next bar

nextBar(Clock.clear)

With a decorator

@nextBar
def change():
    Root.default=4
    Scale.default="minor"
    # etc etc

You can create your own function, and decorate it, to be able to use it in an .every on a Player object

@PlayerMethod
def test(self):
    print(self.degree)

p1 >> pluck([0,4]).every(3, "test")

And cancel it with

p1.never("test")
