This project contains tools related to the Thirty Dollar Website that help creators make better and more complex covers, and users have more enjoyment experiencing public covers and "particle accelerators", free of the lag that you might encounter on the Thirty Dollar Website.
The wiki also has some useful information if you're planning on using these tools. Here's the link
The Thirty Dollar Visualizer is a tool that replicates the Thirty Dollar Website's playback. It plays compositions using multiple CPU threads allowing it to achieve much higher note density and performance, than the website can achieve.
More info about the visualizer here.
The Thirty Dollar Converter is a tool that perfectly outputs a Thirty Dollar Composition to a WAVE audio file. It's the perfect way to make a high quality export of an audio file from a sequence, to use in a video or somewhere else, since it doesn't rely on the performance enhancements the audio engine of the Thirty Dollar Website uses.
The only limitation is your system's RAM capacity and the time you can leave your device powered on.
See more info about the converter here.
Or if you're interested in the CLI program, here.
If you want to download these tools, you can visit the release tab and download the latest copy of the compiled projects, or you can compile this project from the source code.
The officially supported operating systems are Windows x64 and Linux x64, but I also include builds for macOS x64/ARM
