- Evoral::Beats operator!= would prevent an increment of start_beats by intervals of less than a tick, so its possible that other subtle problems existed due to this kind of thing.

This Ardour-specific utility provides an upgrade path for sessions created or\n\
|
|
modified with Ardour versions 5.0 - 5.3.\n\
|
|
It creates a 5.4-compatible snapshot from affected Ardour session files.\n\
|
|
Affected versions (5.0 - 5.3 inclusive) contain a bug which caused some\n\
|
|
MIDI region properties and contents to be stored incorrectly\n\
|
|
(see more below).\n\n\
|
|
The utility will first determine whether or not a session requires any\n\
|
|
changes for 5.4 compatibility.\n\
|
|
If a session is determined to be affected by the bug, the program will take\n\
|
|
one of two approaches to correcting the problem.\n\n\
|
|
The first is to write a new MIDI source file for every existing MIDI source\n\
|
|
in the supplied snapshot.\n\
|
|
In the second approach, each MIDI region have its source converted and placed\n\
|
|
in the session midifiles directory as a new source\n\
|
|
(one source file per region).\n\
|
|
The second method is only offered if the first approach cannot logically ensure\n\
|
|
that the results would match the input snapshot.\n\
|
|
Using the first method even if the second method is offered\n\
|
|
will usually match the input exactly\n\
|
|
(partly due to a characteristic of the bug).\n\n\
|
|
Both methods update MIDI region properties and save a new snapshot in the\n\
|
|
supplied session-dir, optionally using a supplied snapshot name (-o).\n\
|
|
The new snapshot may be used on Ardour-5.4.\n\n\
|
|
Running this utility should not alter any existing files,\n\
|
|
but it is recommended that you run it on a backup of the session directory.\n\n\
|
|
EXAMPLE:\n\
|
|
ardour5-fix_bbtppq -o bantam ~/studio/leghorn leghorn\n\
|
|
will create a new snapshot file ~/studio/leghorn/bantam.ardour from\n\
|
|
~/studio/leghorn/leghorn.ardour\n\
|
|
Converted midi sources will be created in\n\
|
|
~/studio/leghorn/interchange/leghorn/midifiles/\n\
|
|
If the output option (-o) is omitted, the string \"-a54-compat\"\n\
|
|
will be appended to the supplied snapshot name.\n\n\
|
|
About the Bug\n\
|
|
If a session from affected versions used MIDI regions and a meter note divisor\n\
|
|
was set to anything but quarter notes, the source smf files would contain events\n\
|
|
at a PPQN value derived from BBT beats (using meter note divisor)\n\
|
|
rather than quarter-note beats.\n\
|
|
The region start and length offsets would also be stored incorrectly.\n\
|
|
If a MIDI session only contains quarter note meter divisors, it will be unaffected.\n\
