About
Most of my life has been divided between my two greatest passions: arts and technology. I began engaging with music as a child, playing the saxophone at age 7 and moving to drums at 12. Music has always represented the best way to convey emotions for me. My aim is to recreate the same feeling of awe I experience when listening to a great piece of music or when witnessing an exceptional piece of art in my own work. At the same time, I’ve always loved the sciences and strive to find new ways to use my passion for technology to create art. I found the perfect synthesis of these two key aspects of my life in Berklee College of Music’s Electronic Production & Design major and since then I've been spending my time exploring all the different aspects and facets of the audio technology world. My works space from audiovisuals, generative and algorithmic compositions, machine learning based audio software, hardware hacking, custom software for sound processing and music synthesis, live coding, audio post production, mixing and mastering. Some of the commercial products I have worked on in various roles include: Avid Pro Tools, Voicemod ecosystem of apps and Sound Drive.
Software
A selection of personal software projects.
Kairos
Live Coding library written in Haskell using Csound UDP server as the audio engine. Ongoing open-source project started as my thesis for the Bachelor Degree in Electronic Production and Design at Berklee College of Music. For more detail visit the Github page and watch the short video presentation showcasing the state of the project at the end of my senior year at Berklee College of Music.
I had the honor of presenting a paper about Kairos at the 5th International Csound Conference. You can read it here and check out the official Proceedings publication here.
You can see some of my performances at the links provided in the Performances & Talks section of my website
A video I did for Umanesimo Artificiale's Live Code Your Track Live video series where I give some insights about my creative process when performing with Kairos
The Sound of AI - Open Source Research
A sampler powered by Machine Learning. Takes a speech input and generates a guitar sample based on the requested tonal characteristics using a Tensorflow implementation of Spectral Modeling Synthesis. It's then possible to explore the latent space of the generated sample, to create new sounds, or simply perform with the instrument using the on-screen virtual keyboard or an external MIDI keyboard. Written in Python, sound engine for the sampler written in Csound. In this project I served as the co-coordinator of the Production Group, responsible of creating the sampler engine, the state machine and UI for the app and the pipeline to build all the machine learning models built by other research groups into the front end. I also took charge of the evaluation of the project, by contacting and interviewing with creative technology professionals and collecting their feedbacks into qualitative and quantitative reports. The project website is available here. The main repo of the project is available on Github
CSOUND OPCODES
A repository of Opcodes for Csound developed in C++.
So far it includes:
Waveloss : a Csound implementation of the Waveloss UGen from SuperCollider
Pan3 : stereo panning algorithms including constant power sin, constant power sqrt and mid/side panning
Wavefolder : a sine / triangle wavefolder with feedforward and feedback
PdOsc : a phase distortion / phase shaping lookup table precision oscillator
Unicomb : a comb filter with independent feedback and feedforward paths
Available on my Github page
Audio Analysis Experiments
A collection of short Jupyter Notebooks and Python files exploring digital signal processing, audio analysis, music information retrieval and machine learning for audio in Python. All the source code is available on Github and some additional interactive demos and models are available on my huggingface profile
lf.gen
An array of quick DSP algorithms packaged as gen~ patchers for quick prototyping in max/msp. The collection include filters, panners and signal generators. Available on my Github page.
EARLY JUCE EXPERIMENTS: ALPHA DELAY & Basic Synth
Alpha Delay: Stereo delay plugin written in C++ using the Juce framework. Source can be found on my Github page.
Basic Synth: A simple subtractive synthesiser built exploring the Juce framework. Feel free to check it out on my Github page.
Audio Programming for iOs class projects
A number of simple iOs apps developed as class projects. The collection includes an FM synthesizer,a granular delay and a phase vocoder and vocal freezer, together with other audio effects. A selection of them is available on my Github.
Multimedia
Selected works in the field of multimedia art.
DISTANTIA AV
DISTANTIA is a multimedia audiovisual project about the mediated nature of observation blending satellite imagery, virtual spaces and deep immersive soundscapes enriched by AI generated sounds. These elements are weaved together, creating a collection of landscapes viewed from the distant perspective of SENTINEL-2 satellite, processed, analyzed and returned in various types of visualizations, from vast virtual scenarios to distrupted and fragmented pointclouds, inviting viewers into a complex scenario where perception is blurred by the overlap between reality and representation. For this project I worked as applied music machine learning engineer and consultant providing the notebooks necessary to train RAVE models for neural realtime audio synthesis, giving guidance on their use in the studio and for ableton live performances using nn~.
MONAD & SENSE
Multimedia fashion design project in collaboration with Kakan Kudo. I perfomed livecoded music, mixed and mastered it.
CHIAROSCURO
Performance in three acts by Joy Lee that explores the duality of emotions, from dark to light. My roles included performing modular synthesizers and real time processing of the audio from the other players through custom made Max/msp and Csound software.
The video showcases the first iteration of the project, presented on a 10.2 channels sound system with three video screens for projections.
Video of the second iteration of the performance featuring Neil Leonard on saxophone, Aaron Myles Pererira and Kedaar Kumar on Visuals and the dancer Madeline Miller.
DIGITAL FOREST
Multimedia performance produced in collaboration with Nona Hendryx and Will Calhoun. My role in the project was to lead and coordinate a team of students whose objective was to create a website interface through which the audience would have been able to perform and affect the music during the performance, generate the sound effects to be controlled by this web interface, set up the network through which all the performance data was piped and distributed, and regulate how all the teams would use this network to share data with each other based on each team’s needs.
A ROSE OUT OF CONCRETE
Performance produced by Hank Shocklee and Nona Hendryx. This project consisted of a multimedia performance piece featuring 3 projection mapped screens, 15 dancers and 10 music technologists that meant to be an experimental manipulation of the body to produce and control sound, lights and visuals through the use of sensor applied on a group of 15 dancers choreographed by Duane Lee Holland Jr. I was part of the tech team lead by Dr. Richard Boulanger, in charge of developing the devices that, reacting to the gestures of the dancers, manipulated and transformed sounds, visuals and lights. Some of the software I specifically developed for this can be found in software.
SAMSARA
Collaborated on a three-movement multimedia performance realized by A2daC as his final capstone project for the Electronic Production and Design major at Berklee College of Music. My main role in the project was to develop a series of custom Live devices to be used by the artist in the performance. The principal device I created is a Max for Live looper that would allow the player to record and manipulate music on the fly allowing the performer to shape the composition in real time.

"ERASERHEAD" SOUND REPLACEMENT
Sound replacement of the final scene from David Lynch's "Eraserdhead" made for a class project using Ableton Live 10. The original sound design is very sparse, with a lot of silence. In my version I tried to play with silence and harsh sounds to convey the feeling of the scene.
"PI" SOUND REPLACEMENT
Sound replacement of a scene from Darren Aronofsky's "PI" made for a class project using Avid Pro Tools and an Avid S6 control surface. In the sound design of this scene, I tried to express the sonic landscape through the ears of the protagonist, trying to represent the headache afflicting the character.
