mmmh… i think
#define JucePlugin_VSTUniqueID JucePlugin_ManufacturerCode
should be:
#define JucePlugin_VSTUniqueID JucePlugin_PluginCode
or all plugins will have the same manufacturer code.
(i spent a night trying to figure out why plugin hosts recognized wrong ids, so loosing any parameter tweak when saving a song)…
