This is mostly a simple lexical search+replace but the absence of operator< for
std::weak_ptr<T> leads to some complications, particularly with Evoral::Sequence
and ExportPortChannel.
No behavior should be changed by this modification; the argument has a default value of false, which
matches previous semantics, and every instance where the argument is specified, it is given as false.
* share port_latency latency query for MTC and MIDIClock slaves
* propagate set_session()
* share session_connections for MasterViaMIDI
This is in preparation to allow MClk slave to access midi-port-latency
* 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)
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.
Offset the detected timecode instead of the detection time.
The latter is used by the DLL and later also used to calculate
delta times which lead to a constant offset.
in 5.x, we would only run the MTC parsing code if slaved to MTC. That's no longer true in 6.0, and without
this change, MTC will cause a locate at startup
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.
Generated by tools/f2s. Some hand-editing will be required in a few places to fix up comments related to timecode
and video in order to keep the legible
MTC returns not-locked (no flywheel) when the signal is lost, in which case
Session::follow_slave() jumps to no_roll and ignores the slave-position.
The MTC slave does explicitly request a transport-locate and transport-stop.
Yet, Session::realtime_stop() honors _requested_return_frame for whatever
reason
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
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.
