As the title says, just requesting a convenience function to the AudioProcessorGraph for removing nodes by the reference-counted pointer.
When dealing with the graph, you tend to keep Node::Ptr hanging around - so it would make things just a bit more direct. Also, it seems a bit more intuitive to have a removeNode() work the same as addNode().
Perhaps something quick and easy like this?
bool AudioProcessorGraph::removeNode (AudioProcessorGraph::Node::Ptr node)
{
if (node != nullptr)
return removeNode (node->nodeId);
jassertfalse;
return false;
}
