RBLD
Audio

Music Producer · Developer

My name is Robledo Silva. I've been a professional musician for 25 years. Along the way, I kept running into situations where I needed something specific — a particular sound, a particular tool — and it simply wasn't there. That question stayed with me: what if I could just build it myself?

So I started learning to code. Not as a career change — as an extension of what I was already doing. I wanted to understand sound at a deeper level, and writing code turned out to be a way to get there.

Now I realize the solutions that work for me probably work for other musicians and producers too. That's why I launched RBLD Audio — to share some of the instruments, effects, and utilities I've built along the way.

VST3 PAID NEW

RBLD Vivo VST

A multimode VST3 synthesizer with two synthesis engines. The Peak engine feeds a bank of 8 harmonic filters from samples, noise, or live audio — each filter resonates at a harmonic of the played MIDI note, shaping rich, organic timbres. The Resynth engine goes further: it analyzes the sample spectrally and reconstructs it using 8 sinusoidal oscillators with independent decay, controlled through Exciter and Ring — an interface inspired by modal synthesis.

Research Timeline

2.5 years of exploration in audio programming.

Late 2024

First Contact with Pure Data

Began exploring PureData through forums and online patches. Discovered Plugdata — a modern, plugin-ready fork of Pd — and decided to make it my main research platform.

2025

A Year of Building

Deep dive into Plugdata. Released RBLD PolyShifter and Peak-o-Synth Prototype, both available inside the Plugdata store. Developed BobGranulator as a VST export. Built a custom C++ + Dear ImGUI tool to design GUIs for Plugdata-exported plugins. Started learning C++ from scratch.

Late 2025

Peak-o-Synth VST3 Development Begins

Started rebuilding Peak-o-Synth as a native VST3 plugin in C++ using the JUCE framework. Used Figma to design the full GUI from scratch, aiming for a polished, commercial-grade instrument.

May 2026

Vivo VST — Released

After extensive testing, refinements — and a rename. The plugin built throughout the year as Peak-o-Synth VST3 launched under a new identity: RBLD Vivo. A multimode polyphonic synthesizer that uses tuned frequency peaks to extract notes from non-harmonic sources, plus a spectro-modal resynthesis mode, developed in C++ with JUCE and a custom Figma-designed GUI.
