Manages an Ableton Link session connecting an Edit with a number of networked peers, syncronising their tempos, bar phases and start/stop statuses. More...
Classes | |
| struct | Listener |
| When Link is on, you shouldn't set the tempo directly. More... | |

Manages an Ableton Link session connecting an Edit with a number of networked peers, syncronising their tempos, bar phases and start/stop statuses.
| tracktion::engine::AbletonLink::AbletonLink | ( | TransportControl & | ) |
Creates an Ableton Link connection for an Edit.
Don't create one of these manually, get the one contained in the Edit with Edit::getAbletonLink().
| tracktion::engine::AbletonLink::~AbletonLink | ( | ) |
Destructor.
| void tracktion::engine::AbletonLink::setEnabled | ( | bool | isEnabled | ) |
On iOS you need this to instantiate an ABLLinkSettingsViewController.
Enable Link. On platforms other than iOS, Link connects automatically once this is set. On iOS the user must additionally switch Link on using the ABLLinkSettingsViewController. Off by default on desktop, on by default on iOS.
| bool tracktion::engine::AbletonLink::isEnabled | ( | ) | const |
Is Link enabled? It may not be connected to any peers even if it is.
| bool tracktion::engine::AbletonLink::isConnected | ( | ) | const |
Is Link connected to any other peers?
| size_t tracktion::engine::AbletonLink::getNumPeers | ( | ) | const |
Returns the number of connected peers.
| bool tracktion::engine::AbletonLink::isPlaying | ( | ) | const |
Returns whether the Link transport is currently playing.
| void tracktion::engine::AbletonLink::enableStartStopSync | ( | bool | enable | ) |
Sets whether start/stop is syncronsied.
| bool tracktion::engine::AbletonLink::isStartStopSyncEnabled | ( | ) | const |
Returns whether start/stop is syncronsied.
If you're not connected, this may not make sense.
| double tracktion::engine::AbletonLink::getSessionTempo | ( | ) | const |
Get the current session tempo.
If you're not connected, this may not make sense.
| double tracktion::engine::AbletonLink::getBeatsUntilNextCycle | ( | double | quantum | ) | const |
Number of beats until the next bar (quantum) - e.g.
supply 4.0 for 4/4 cycles.
| void tracktion::engine::AbletonLink::setCustomOffset | ( | int | offsetMs | ) |
Use to offset the calculations by some amount (on top of device latency).
| void tracktion::engine::AbletonLink::setTempoConstraint | ( | juce::Range< double > | minMaxTempo | ) |
Once set, tempos chnages from link are transparently divided or multiplied by 2 to stay within this range (if possible).
| double tracktion::engine::AbletonLink::getBarPhase | ( | ) | const |
Returns how far though the current bar the Link clock is.
| double tracktion::engine::AbletonLink::getChaseProportion | ( | ) | const |
Returns how much chasing playback is doing.
0 means perfectly in sync 1 means playback is speeding up as much as it can -1 means playback is slowing down as much as it can
| void tracktion::engine::AbletonLink::requestStartStopChange | ( | bool | isPlaying | ) |
Request the Link session to start or stop playing.
This will in turn trigger a callback to linkRequestedStartStopChange which should be used to actually start the transport. [[ message_thread ]]
| void tracktion::engine::AbletonLink::requestTempoChange | ( | double | newBpm | ) |
Request the Link session to change tempo.
This will in turn trigger a callback to linkRequestedTempoChange which should be used to actually change the tempo. [[ message_thread ]]
| void tracktion::engine::AbletonLink::addListener | ( | Listener * | ) |
Adds a listener.
| void tracktion::engine::AbletonLink::removeListener | ( | Listener * | ) |
Removes a previously added listener.
| void tracktion::engine::AbletonLink::syncronise | ( | TimePosition | ) |
