improve release behavior.
This slows down the release after events like single snare hits as, the gain
reduction only releases to 160 dB rather than to inf.
To properly visualize attack and release we calculate the input level out of
the gain reduction the output level threshold and ratio.
if (output_level >= threshold) { // no expansion
input_level = output_level
} else {
input_level = (gain_reduction - threshold * (1-ratio)) / ratio
}
This fixes duplicate AU presets when adding a new preset.
Presets are kept in a std::map<URI,...> adding a new presets uses
the file-URI as ID. Loaded presets needs to have the same URI.
Unsigned long is 32bit on 32bit systems, besides sampleoffset and start
variables are signed int64_t.
resulting in a compiler error:
integer constant is too large for 'unsigned long' type.
set_block_size() implies plugin deactivate(), activate() calls
to re-initialize AU and VST plugins. So plugins will reset the
internal state and not immediately respond correctly.
Some plugins zero the output or ramp up internally, leading the analyzer
to show invalid or random/uncorrelated information.
This avoid periodic calls to de/activate()
Changing a tooltip resets the timeout. In one particular case,
while rolling, AudioClock::set() is calling set_tooltip() at a rate
faster than the tooltip timeout and prevents tooltip from showing at all
(even if there is no actual change to the tooltip text).
Alas, there is no trivial fix for this UI side and there may be other
such cases. A central check is more than practical.
smf_delete() does not handle NULL, and segfaults instead.
This only crashes with optimized builds.
libsmf will call g_critical() earlier and in that case debug-builds
call UI::handle_fatal() and ask the user to "click to exit".
This fixes VST parameter prop.flags (toggle, integer-step).
VestigeMaxLabelLen is used in various places in libardour, most notably
with effGetParamName.
It conveyed the idea of continuous silencing as long as the transport
is in a stopped state. Make it correctly mean a one-shot reset when the
transport is being stopped.
CoreMIDI ports are dynamic. When dis/connecting a device CoreAudio's
AudioHardware-PropertyListener triggers a callback which can
add/remove ports.
This can not happen concurrently with processing, but it may happen
concurrently with a user creating tracks using Ardour's UI
and/or session-load/setup.
Don't call ::set_value() if the actual value has not changed.
e.g. MIDI-CC or integer controls. Moving the Bar-controller was able to
create events even though the actual value remained unchanged.
This check has to be done UI-side, since the underlying API is also used
for state-restore and automation. e.g.
"old value" (user-set) may be default "0", "new value" may also be "0" but
libardour still needs to send an event (a synth's internal state may not
default to "0")
