2020-05-13Set timecode format from active master onlyRobin Gareus
2020-05-12Consolidate delta-string format, avoid markupRobin Gareus
2020-05-11Slave delta display tweaksRobin Gareus
* use left-aligned sign symbol with "sample" unit. When the delta value jitters in decimal places (e.g. MTC) it's otherwise no possible to discern + vs -. * Use white text by default (not green)
2020-05-11Fix TCM requiring port-reconnect when engine restartsRobin Gareus
An engine restart sends dis-connect messages for the reverse port-mapping (after making the connection): Connect: system:midi_capture_41a56f90 -> ardour:MTC in Connect: system:capture_1 -> ardour:LTC in DisConnect: ardour:MTC in -> system:midi_capture_41a56f90 DisConnect: ardour:LTC in -> system:capture_1 This lead to TransportMaster being marked as inactive. This is likely an issue that should be fixed elsewhere, but in case of JACK, we likely do not have control over this.
2020-05-10LTC: sync-lock is only relevant when clock is syncedRobin Gareus
2020-05-09Update LTC reader port latency on connection changeRobin Gareus
This mechanism adds infrastructure that can later also be used for MTC and MIDIClock. PS. The LTC Generator port's latency is queried after the port is created, and later kept in sync via LatencyUpdated signal.
2020-05-08LTC Slave: subscribe to LatencyUpdated signalRobin Gareus
This uses a recently introduce Signal instead of the generic GraphReordered, which was used in the past since it usually happened after the latency was changed.

2019-01-25new approach to handling Transport Masters when engine is restartedPaul Davis
Trust that ::reset() works for all transport masters, and call it when engine is stopped. This way the transport masters are ready to be called again as soon as the engine restarts.

2017-09-18attempt fix for LTC slave when locatingPaul Davis
2017-07-26Fix initial sync to LTC with small buffersizesRobin Gareus
Ardour follow_slave() does nothing (not even seek) if the slave is not locked. The LTC-slave assumes it's locked if LTC is stable for 5 continuous process-calls. If the difference of Ardour's transport-position to the LTC-timecode is large (> 2sec), the slave reset itself (assuming drift, seek don't vari- speed). A LTC-slave does reset does reset the locked counter. Hence: If initially Ardour's transport differs > 2 sec and the buffersize is small (many process-callbacks), the slave kept resetting itself never informing Ardour that it locked to the external TC, and Ardour never issued a seek.
