Public Attributes
std::function< void()>	code
	this lambda function is executed each step, at the timing assigned to the class. Assign your own functions to it. The step number is passed to the function as int value. Remember that this function will be executed into the audio-thread so the access to some variable used also into the main thread could cause race conditions.
std::atomic< int >	timing
	timing for the function frames, defaults to 16 ( 1/16th of a bar ). Thread-safe to set.
std::atomic< bool >	active
	enable / disable exectution of lambda, true by default, Thread-safe to set.
