About this Gig
Have a VST plugin idea but no working software?
Maybe your plugin crashes in Ableton, presets won't save, or the interface looks nothing like you imagined.
I develop custom VST3 and AU audio plugins using JUCE, C++ and DSP, helping producers, sound designers and audio brands build effects, instruments and MIDI tools.
WHAT I OFFER:
- Custom VST3 and AU plugins
- JUCE C++ audio development
- EQ, reverb, delay, distortion, compression
- Synthesizers and MIDI effects
- DSP processing and filters
- Modern plugin GUI and controls
- Preset saving and automation
- Ableton, FL Studio, Logic Pro, REAPER testing
- Windows and macOS builds
- Plugin debugging and optimization
TECH STACK:
Frontend: JUCE GUI, C++ and optional WebView UI.
DSP/backend: JUCE DSP, C++ audio engine, MIDI, CMake.
Database: SQLite or JSON when preset storage needs it.
APIs: VST3 SDK, Apple Audio Units, JUCE modules.
Delivery: GitHub source, tested builds, optional Hostinger-hosted licensing API.

FAQ
Can you develop a custom VST3 or AU audio plugin from my idea?
Yes. If you have an idea for an EQ, compressor, reverb, delay, distortion effect, synthesizer or MIDI tool, I can review the functionality and create a development plan. I use JUCE and C++ for audio processing and plugin interfaces. Before starting, we will agree on the controls, audio behavior etc
Will my VST3 audio plugin work in Ableton Live, FL Studio, Cubase and REAPER?
VST3 plugins can be developed for compatible hosts including Ableton Live, FL Studio, Cubase and REAPER. However, each DAW has its own hosting behavior, and compatibility must be tested rather than assumed. Tell me the DAW name, version and operating system you use. I will specify which hosts can be
Can you build an AU plugin for Logic Pro on macOS?
Yes. Audio Units are Apple's plugin format, and JUCE supports AU builds on macOS. I can develop an AU effect or instrument for an agreed macOS target, including parameter controls and preset handling. macOS build access, code signing, Apple Silicon compatibility and Logic Pro testing should be confi
Can you fix an existing JUCE VST3 plugin that crashes or fails to load?
Yes. I can investigate plugin scanning failures, initialization crashes, audio-processing problems, missing dependencies and build configuration errors. Please send your JUCE version, source project if available, operating system, DAW version and crash logs. I will reproduce the problem where possib
Do you develop DSP effects such as reverb, EQ, compression and distortion?
Yes. I work with C++ and JUCE DSP components to implement effects such as filters, EQ, gain control, distortion, delay and compression. Reverb, pitch processing and more advanced algorithms require additional design and testing. I will confirm the required audio behavior, controls, CPU expectations
Can you design a custom GUI with knobs, meters, waveforms and presets?
Yes. I can develop a plugin interface with rotary knobs, sliders, buttons, meters, preset selectors and suitable waveform displays. JUCE provides native interface components, and a WebView-based interface may also be possible depending on the project. The final design can follow your branding
Can you build a MIDI plugin, virtual instrument or synthesizer using JUCE?
Yes. JUCE supports MIDI processing and virtual instruments, including note handling, modulation and synthesis. I can assess MIDI effects, simple synthesizers, samplers and instrument interfaces. A basic MIDI processor differs substantially from a commercial synthesizer with multiple oscillators etc
Can you develop VST3 and AU plugins for both Windows and macOS?
Yes, subject to the agreed formats and available build environments. VST3 can target Windows and macOS, while AU targets Apple's platforms. I use CMake, Visual Studio and Xcode where appropriate. Platform-specific dependencies, Apple Silicon support, installers, signing and DAW testing included
Can you add licensing, user accounts, preset downloads or a plugin website?
Yes. These are optional additions to the core audio plugin. A licensing portal or online preset library may use React or Next.js for the interface, Node.js for backend services, PostgreSQL or SQLite for storage, and a hosting provider such as Hostinger. I can also assess authenticated APIs etc
What do you need before starting my JUCE C++ audio plugin project?
Please send a short description of your plugin, its main audio effect or instrument behavior, reference sounds, desired controls, target DAWs, operating systems and preferred VST3 or AU formats. If you already have source code, include the project version and any errors.
