It can happen that ::get_request() returns NULL if the
EventPool is full. In that case the slot is never called.
In this case the caller can now take action.
Plugins on Apple can be multi-arch (Intel + ARM), or AUs may
be bridged by Rosetta.
A user can also run Intel binary of Ardour or M1 binary on
M1 CPUs on macOS. Each can see different plugins - notably
VST3 plugins that are Intel only can be scanned using the
Intel binary, but are later not available with the M1 build.
fix bindings to shifted symbols (see below)
add shortcuts to recorder, virtual midi keyboard
change shortcut (secondary+c) from Big Clock to Cue page
(*) shifted symbols like '+' are accessed in a very specific way, like:
<@TERTIARY@>plus
and
<@SECONDARY@><@TERTIARY@>plus
RegionView::make_name already adds the prefix, AudioRegionView
does not need to add it again.
Also the font used on macOS (Lucia Grande) has a rather limited
UTF-8 charset and does not support:
\u20F0 (COMBINING ENCLOSING CIRCLE BACKSLASH)
\U0001F507 (SPEAKER WITH CANCELLATION STROKE)
so for now we keep using "!" on macOS.
* expand/shrink track height
* stem-export selected tracks
* create a range from selected regions
* consolidate range
* add a single Range marker for selected region(s)
* unlink (fork) midi region from linked regions
* toggle plugin manager window
* fixed shortcut for Crop
* moved "audio patchbay" from Alt-P to Alt-Shift-A,
making it more consistent with Alt-Shift-M: MIDI patchbay

* Fix deflection when using percent (use sqrt/pow2)
* Simplify linear deflection when using semitones
* Allow deflection of > 200% when using semitones
There is no longer an extra set of rt-threads, but existing
process-graph threads are reused.
There are two main benefits to this approach: graph-threads
have a SessioEvent pool and ProcessThread buffers. They are
also joined to work-groups (on macOS), or JACK created threads
(cgroups).
The process-graph trigger_queue only needs to call
::prep() and ::run() without knowing any further details.
This is in preparation for using the graph-threads for rt-tasks
The AudioClock uses samples. Duration calculation is
done using the current clock pos. The returned distance is
using Beats, can be directly used for all notes regardless of their
position.
Now that this works correctly the dialog can also be made available
for multiple-selection.
Route::silence() runs plugins. With a heavy session
that relies on multi-core processing, sending silence
to processors will have to be done in parallel.
Otherwise it can result in large DSP load and xruns.
This may allow to revert b3497b3f8f, which was
a prior attempt to resolve this, before understanding
the actual cause.
When auditioning, ardour's process_audition calls Route::silence
for all routes. PluginInsert::silence simply fed all [ports of all
[replicated] plugins with silence, regardless of port-mapping.
This can cause some VST2/3 plugins to change state, and enable ports
(e.g. stereo VST2 plugins on mono tracks), causing glitches.
This commit is mainly intended to investigate how significant
this glitch is when starting to audition.
