We accomplish this by explicitly setting the global_obs to NULL after
free'ing it. The crash that led to this fix can be replicated as such
$ sendosc localhost 3819 /set_surface i 8 i 159 i 8
$ sendosc localhost 3819 /set_surface i 0 i 0 i 0
$ sendosc localhost 3819 /set_surface i 0 i 0 i 0
In this example the observer is created, then free'd, and then free'd
*again* because the new observer was never made (sur->feedback[x]
checks fail)
Mixbus v6 uses AutomationType BusSendLevel like other Sends,
however with different min/max range compared to default Ardour
Aux sends. Control surfaces should use interface/internal API.
"Always use Tabstops for block-indent (the code must be
formatted correctly with "[TAB] = N spaces" for any value of N).
Use space only for alignment." - https://ardour.org/styleguide.html
This fixes an issue with "/route/eq/freq/0 S1":
When a newly select strip that does not have a EQ
(e.g. mixbus or master), the control from the previously
selected strip is used. -- Reported by tavasti on IRC.
* add an option to the controller configuration gui
to assign the 3x2 send banks in mixer mode
to either the upper (1-6) or lower (7-12) Mixbus sends
* This was a user request to better support the workflow
of the CoMondo Mix system
Previously this was inherited via PBD.
On MacOS/X, this adds
"-undefined dynamic_lookup -flat_namespace"
and various "-framework .." options to linkflags
Without this flag, .dylibs fail to link usually because
of missing `-lintl` (Undefined symbols: "_libintl_dgettext")
On other systems this is a NO-OP:
CFLAGS_OSX, CXXFLAGS_OSX and LINKFLAGS_OSX
are only set on the darwin platform.
Some builds of glib on macOS end up delivering IO_PRI when IO_IN is also set. This differs from our own build stack
version, but it isn't really an error, so we should handle it.
