I've always enjoyed the immersive feel of 3D audio and wanted to see how far I could stretch that.
In Dear VR Micro the elevation is showing if the sound is above or below you and i'm sweeping from front to back with the stereo width constantly changing (I'm using the envelopes in the Europa Synthesizer to modulate everything).
If there's any Reason users out there I recommend grabbing Kushview Element, it will allow you to run VST3 in Reason 9.5 or later. It's also possible with Voltage Modular Core by Cherry Audio.
Headphones are highly recommended.
