Interactive Audio

After studying Video Game Music Implementation at Berklee College of Music, Gregory discovered the power of VR to convert movements of the body into inputs that could be used to trigger musical events.

Rave Gazebo

Rave Gazebo is a dance-interactive virtual reality album that uses your dancing to remix a song in real time. The main input is simply gesturing in one of six directions, which switches between pre-composed layers of music. Each gesture interacts with the environment, sending physics objects into the scene and generally creating chaos. Learn more in our special Rave Gazebo Page!

Composer Demo Reel

Here is a video compilation of the projects Gregory worked on in interactive audio from 2019, before pivoting to focus his efforts on virtual reality.

Ambisonic Tutorial

While interning at the Brookline Interactive Group, Gregory created this tutorial on how to quickly and cheaply create ambisonic files using Reaper and the Ambisonic Toolkit

Simulation Series
Interview

Gregory was given the opportunity to talk about his work on interactive music in virtual reality with the Simulation Series in 2019 while he was still at Berklee. He has been working ever since to bring his visions to reality.

XR Instructor

Starting in the middle of the Covid-19 lockdown, Gregory was hired to work on developing curriculum for the online boot camp at XRTerra.

 

He has used his own VR development journey to create hands-on courses with a heavy emphasis on live troubleshooting and support.

VR Developer Foundations

This is an 8-class course that teaches you the foundations of VR development in the 3D Engine Unity, introducing the XR Interaction Toolkit, Collision and Trigger Detection, Animations, with an emphasis on learning C# programming fundamentals

AR Playground: CoSpaces

Many school systems in the US do not have access to computers that can run more powerful programs such as Blender and Unity, and instead rely on Chromebooks to give their students internet access. In order to teach these students XR development skills, Gregory created a course that can be taught using only web-based applications like CoSpaces and Tinkercad.

AR Playground: Reality Composer

The iPad is an incredibly powerful device with several key pieces of hardware that make it a useful tool for the 21st century. This course has students take advantage of the camera, microphone, and internet access of their iPads to create their own interactive Augmented Reality experience in Apple's Reality Composer app.
