2017-09-18globally change all use of "frame" to refer to audio into "sample".Paul 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.

2015-06-29Add some libardour support for indicating MTC active status.Paul Davis
The general design here is wrong, because it should be more general and cover all possible sync sources. But it does work, it is used in Tracks, and my attempt to do it correctly revealed the problem to be an EXTREMELY difficult design issue (as in: two weeks of work on it did not really solve the fundamental issues with slave design). So, here it is for now, c/o Grygorii

since transport_frame refers to cycle start, the should be position has to account for position of the midi clock event.

2013-08-13fixes to get MTC (and probably MIDI clock) slaving working againPaul Davis
incoming MIDI data has to be parsed EVERY process cycle, not just when Slave::speed_and_position() is called. The private MIDI::Parser owned by the MTC and MClck slaves was irrelevant, since the port has its own. See comments in midi_port.h on the strangled inheritance heirarchy.

2012-11-13implement TC offset for slave&generator.Robin Gareus
Many related changes that require atomic update, mostly because ClockOption slots changed: * change offset config format to std:string (backwards compat - reads 0) * make Timecode offset independent from fps * sample_to_timecode() handle negative sample-num * audio-clock fix entry and edit of negative numbers * option editor: - remove old global internal offset - add slave & generator TC entry - still needs UI cleanup, tooltops, maybe sep. tab.. * LTC & MTC slave& generator: - cache offset - subscribe to parameter changes git-svn-id: svn://localhost/ardour2/branches/3.0@13485 d708f5d6-7413-0410-9779-e7cbd77b26cf
