FAQ
What plugin formats do you develop?
I develop VST, VST3, AU, and AAX plugins using JUCE and C++. Your plugin can run on Windows and macOS and work inside DAWs like Ableton Live, FL Studio, Logic Pro, Cubase, Pro Tools, and Studio One. Cross-platform stability and proper DAW integration are always prioritized.
Can you fix crashing or non-scanning VST plugins?
Yes. If your VST/VST3 plugin fails to scan, crashes in Ableton or FL Studio, or causes CPU spikes, I can debug the issue, analyze logs, correct DSP errors, and resolve compatibility problems. I also handle blacklisting, buffer errors, and plugin validation issues.
Do you build custom audio effects or synthesizers?
Yes. I develop custom audio effects (EQ, compressor, saturation, delay, reverb) and synth plugins (wavetable, granular, MIDI-based instruments) with full DSP processing. Each plugin includes parameter automation, preset management, and professional GUI design.
Will my plugin have a professional GUI?
Absolutely. I design clean, modern GUI/UI layouts optimized for music production workflows. Interfaces can be created in Figma and implemented directly in JUCE. You’ll get resizable UI, Retina/HiDPI support, smooth controls, and intuitive parameter mapping.
Can you optimize my plugin for low CPU usage?
Yes. I implement efficient DSP architecture, oversampling control, and buffer optimization to ensure low CPU usage and low latency performance, even in heavy DAW sessions. Performance stability is tested across different buffer sizes.
Do you provide presets and preset systems?
Yes. Your plugin can include a complete preset management system, preset browser, factory presets, and user preset saving. I can also design sound presets for synth plugins if required.
Do you support MIDI and automation?
Yes. Plugins can include MIDI input, MIDI learn, automation compatibility, MPE support, and parameter recall inside DAWs. All parameters are mapped correctly for smooth automation and session recall.
Can you package installers for Windows and Mac?
Yes. I provide build exports and can assist with installer packaging, basic code signing guidance, and plugin validation preparation for both Windows and macOS environments.
How do we start a custom VST plugin project?
First, share your plugin concept, reference plugins (if any), required DSP features, and target formats (VST3/AU/AAX). I’ll review the scope and provide a structured development plan, timeline, and cost estimate.
Do you provide source code?
Source code delivery is available depending on the package selected. If you require full JUCE/C++ source ownership for long-term development or investor presentation, we can structure the project accordingly
