Detailed Description

When Link is on, you shouldn't set the tempo directly.

Instead add yourself as a listener, call requestTempoChange() and wait for a linkRequestedTempoChange() callback.

If a large position change is required to get in sync with other clients, linkRequestedPositionChange is called and the listener user must perform it. Usually, however, this object can perform some nudging to keep in sync.

~Listener()

virtual tracktion::engine::AbletonLink::Listener::~Listener ( )

virtualdefault

Destructor.

Member Function Documentation

linkRequestedStartStopChange()

virtual void tracktion::engine::AbletonLink::Listener::linkRequestedStartStopChange ( bool  isPlaying )

pure virtual

Called by link to request that tracktion starts or stops its tempo.

linkRequestedTempoChange()

virtual void tracktion::engine::AbletonLink::Listener::linkRequestedTempoChange ( double  newBpm )

pure virtual

Called by link to request that tracktion changes its tempo.

linkConnectionChanged()

virtual void tracktion::engine::AbletonLink::Listener::linkConnectionChanged ( )

pure virtual

Called by Link when the number of peer connections changes.

linkRequestedPositionChange()

virtual void tracktion::engine::AbletonLink::Listener::linkRequestedPositionChange ( BeatDuration  adjustment )

pure virtual

Should be implemented to perform a larger beat position change.

N.B. This will be called on the audio thread and the beat adjustment should take place before the next audio block. This usually means posting a position change directly in to the EditPlaybackContext. Just make sure you don't block during this callback. [[ audio_thread ]]
