Convert C array to Juce Array

Ah, yes, you can sort of do that. It’s got a couple of issues you, it won’t write to XML properly:

Unless you really want it in an Array I’d be tempted to go with something like this:

for (auto i: originalArray)
{
  ValueTree node{"n"};
  n.setProperty("value", i, nullptr);
  tree.addChild(node, -1, nullptr);
}

or similar which then gives you the option of writing to XML still. There may be reasons why Array would be better … someone else may have a view.
