I'd appreciate any help anyone can provide with this. Has anyone here run into similar problems with making MIDI Effect Plugins for FL Studio? I also tried this setup with an omni instrument in EastWest Play, but that didn't work either: I would like to get this example working with FL studio so that I have a foundation I can build upon. This allows me to add the plugin to Patcher as a generator (where it would fail to load as a generator before), but with the setup being the same as the above images, there is still no MIDI going from ArpeggiatorPlugin to Sytrus. I also tried checking the 'Plugin is a Synth' box under Plugin Characteristics in the Projucer settings. Arpeggiators earned their name from the arpeggioa phenomenon in music theory where notes of a chord are played one after another in sequence. That's without touching the Projucer settings. An arpeggiator is a synthesis tool that uses MIDI or control voltages to cycle through a series of notes according to a clock rate and note division. But for some reason it does not work with this plugin example. The setup and settings shown above work perfectly when I use CodeFN42 RandARP - the midi will pass through the wires into Sytrus as an arpeggio of the chord I'm playing. Yet when I hook up the MIDI wires to Sytrus, there is no midi output from the plugin. The MIDI input node doesn't appear in Patcher until I modify the input and output port numbers in the Arpeggiator plugin. At this point I can only drag the plugin into Patcher as an effect - it fails to load if I drag it in as a generator. It starts lacking behind after 3 or 4 notes are played.

However, the note repeater/arpeggiator gets off-beat very fast. I have successfully synced the BPM of FL Studio with my MPK, so changing the BPM in FL Studio also changes the density of notes/sound that I am playing. I selected ArpeggiatorPluginDemo, built it in Visual Studio 2019, and copied the built VST3 files into my Common Files VST3 directory so FL studio could discover them. However, I have witnessed a problem with the arpeggiator and note repeater. This has me excited because I can learn how to make my own MIDI manipulation plugins to drop into Patcher in FL Studio. I found an arpeggiator example in the Projucer in File -> Open Example -> Plugins -> ArpeggiatorPluginDemo.
