* Move m_key member of Effect into Plugin
* Pass key to Instrument ctors and instantiaters
* Add pluginKeys to all plugin selector widgets, and let them pass the keys
when instantiating the instruments; or, if the keys must be passed over
threads, pass the keys to the Engine using `Engine::setDndPluginKey()`
* As instrument plugin libraries now also need to get their key passed, their
second argument, which was always the same as the first, is now used to pass
the sub plugin keys. This affects *all* instrument plugins.
* Plugin.h: Add more virtuals to `SubPluginFeatures` in order to draw logos
and images into instrument selector widgets
* LadspaSubPluginFeatures: Implement the `displayName` virtual because the
new behaviour to resolve displayNames is to first look at the
SubPluginFeatures, which, without override, returns the superior plugin's
name (Plugin.cpp)
Additional:
* PluginFactory.h: Allow setting up search paths without discovering plugins
yet
* Plugin.h: Add full documentation (should be checked)
* Remove bin2res, use Qt's resource system
* Use QDir search paths and QImageReader in getIconPixmap
* Don't include "embed.cpp" in plugins
* getIconPixmap: Use QPixmapCache, use QPixmap::fromImageReader
* Require CMake 2.8.9
* Fix ReverbSC embed usage
I removed code in a previous commit that deleted ended samples since
that sometimes caused issues when the samples had loop points. However,
removing the code caused issues with the release samples. Thus, now it
removes ended samples only if they are release samples. Otherwise, the
keyup event and ADSR handle ending the note.
Previously if you release a C4 then all C4 notes would be released. Now
it stores the pointer to the plugin data which is unique for each key
press and determines which to release based on the matching pointers.
Now it'll honor the loop regions specified in the file and it'll
properly use the fine tuning for the samples if specified. Also,
modified the exponential decay code again since it was glitching at the
end of some notes for some reason.
Now if a Gig file provides a few samples per octave, it'll change the
pitch of the sample specified for a note instead of just assuming it is
the right pitch.
Also, fixed issue where if attack length was zero the note would never
sound.
Moving the code to detect the sample rates of the currently used samples
after the code deleting notes seemed to fix these glitches. Also, fixed a
few ADSR issues that could have resulted in clipping in the attack or
glitching after the release.
When providing extra frames, libsamplerate stores the extras internally
and outputs them in the next period. But, when it has enough internally
to output a whole period, it just outputs the internal buffer while not
using any more input frames. Now I provide some extra frames, check to
see how many frames we used actually used, and update the sample
positions and ADSR accordingly.
