Detailed Description

• The synth engine implements the entire synth architecture and SynthEngine is the single C++ object you need to add to your plugin framework’s processing object.
• In the example plugins designed with ASPiK, this is the PluginCore C++ object, for JUCE it is the AudioProcessor object.
• Each of the synth projects is packaged in a single SynthEngine object, which is implemented in synthengine.h and sythengine.cpp and located in a directory with the other supporting object files.
• These objects are framework agnostic meaning that they are pure C++, have no bindings to any plugin framework and do not require additional libraries beyond the built-in standard template libraries included in your compiler.
• The engine performs three tasks during the synth’s operation:

1. initialization,
2. applying GUI control changes, and
3. rendering the synthesized audio.

• I designed the SynthEngine object to expose simple functions that service these operational functions, with an interface that is not dependent on any plugin framework.
• Your plugin framework’s processing object will create and use the engine object – it is the sole C++ object and interface that you need to wire-into your plugin.
• After instantiation, the plugin will call five methods on the engine for the three engine functions as seen from the plugin/DAW side:

1. Initialization: the plugin calls the engine’s reset and initialize functions
2. Set GUI Parameters: the plugin calls getParameters for a shared pointer to the engine’s GUI connected parameters and setParameters to instruct the engine to update its states, causing a trickle-down transfer of parameters using shared pointers and without data copying
3. Rendering Audio: the plugin calls the engine’s render function, passing it audio buffers to fill one a block by block basis
