Since:

SkyMonome v1.3

divisions

protected int divisions

Number of divisions by quarter note used by this sequencer engine.

Since:

SkyMonome v1.3

Constructor Detail

SequencerEngine

public SequencerEngine(Monome monome,

                       float tempo,

                       int divisions,

                       S... sequencers)

Constructs a sequencer engine with the specified logical Monome device, the specified tempo, the specified number of divisions by quarter note, and driving specified sequencers. These sequencers can also be added after the construction.

Parameters:

monome - Logical Monome device for refreshings.

tempo - Tempo, in number of quarter notes by minute.

divisions - Number of divisions by quarter note.

sequencers - Sequencers that will be driven by this sequencer engine.

Method Detail

getDivisions

public int getDivisions()

Returns the number of divisions by quarter note currently used by this sequencer engine.

Returns:

The number of divisions by quarter note currently used by this sequencer engine.

Since:

SkyMonome v1.3

setDivisions

public void setDivisions(int divisions)

Modifies the number of divisions by quarter note of this sequencer engine.

Parameters:

divisions - New number of divisions by quarter note used by this sequencer engine.

Since:

SkyMonome v1.3

getTempo

public float getTempo()

Returns the current tempo of this sequencer engine.

Returns:

The current tempo of this sequencer engine.

Since:

SkyMonome v1.3

setTempo

public void setTempo(float tempo)

Modifies the tempo of this sequencer engine.

Parameters:

tempo - New tempo for this sequencer engine.

Since:

SkyMonome v1.3

setTempo

public void setTempo(float tempo,

                     int divisions)

Modified the tempo and the number of divisions by quarter note currently used by this sequencer engine.

Parameters:

tempo - New tempo for this sequencer engine.

divisions - New number of divisions by quarter note used by this sequencer engine.

Since:

SkyMonome v1.3

getSequencers

public S[] getSequencers()

Returns an array of all associated sequencers.

Returns:

An array of all associated sequencers.

addSequencer

public void addSequencer(S sequencer)

Adds the specified sequencer to the list of associated sequencers.

Parameters:

sequencer - Sequencer to add to the list of associated sequencers.

removeSequencer

public void removeSequencer(S sequencer)

Removes the specified sequencer from the list of associated sequencers.

Parameters:

sequencer - Sequencer to remove from the list of associated sequencers.

removeSequencers

public void removeSequencers()

Removes all sequencers from the list of associated sequencers.

refreshMonome

public void refreshMonome()

                   throws MonomeException

Refreshes the physical Monome device. This method garantees the fastest way to refresh the physical Monome device, but the difference is significant only when your Monome tree is very deep.

Throws:

MonomeException - When the Monome device can't be refreshed.

getTimeBetweenSteps

public double getTimeBetweenSteps()

Returns the calculated time between two consecutive steps.

Returns:

The calculated time between two consecutive steps.

run

public void run()

Invoked by the virtual machine to execute this thread.

Specified by:

run in interface java.lang.Runnable

Overrides:

run in class java.lang.Thread
