Implementation of the Lv2 core, except for CV ports. No features or
extensions are supported yet.
You can now generate sound using Lv2 instruments (restricted to non-piano)
or effects.
For an explenation about the new classes, see Lv2Manager.h
right place when it not played from the begining.
That has created a difference between the ticks and the metronome and
the sample track.
The cause of the problem was that the calculation of the frame to play
was wrong: we had calculated `framesPerTick` according to the current
engine's sample rate instead of the SampleBuffer's sample rate.
* 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)
