public static boolean VERBOSE

Method Details

start

public static BeatMIDI start(Object pListener,
 String pMidiInput)

Parameters:

pListener - object which implements the method `beat(int beatCounter)`

pMidiInput - MIDI input device to listen to

Returns:

BeatMIDI

reset_beat_counter_at_stop

public void reset_beat_counter_at_stop(boolean pResetBeatCounterAtStop)

Parameters:

pResetBeatCounterAtStop - if `true` the beat counter is reset to `0` when the MIDI clock signal stops.

running

public boolean running()

Returns:

true if beat is running

beat_count

public int beat_count()

Returns:

current beat count in pulses per quarter notes (PPQN)

bpm

public float bpm()

returns an estimate of the current BPM deduced from the duration between two ticks ( or pulses )

Returns:

estimated BPM ( might be imprecise in the first few beats )
