FL Studio RPC Tracker

A tool for tracking FL Studio project playback status, BPM, pitch, and other metrics in real-time.

Preview

How It Works

The tracker works by reading FL Studio's memory in real-time to extract information about the current project:

• Memory Scanning: Scans FL Studio's engine module (FLEngine_x64.dll) for known patterns to locate BPM, pitch, metronome state, playback status, song position, and song/pattern mode.
• Value Reading: Reads values directly from FL Studio's process continuously.
• Discord RPC Update: Updates your Discord profile with the current project details according to the template in config.json.
• Customizable Display: Use placeholders ({Project}, {BPM}, {Pitch}, {Metronome}, {Mode}, {Status}, {Position}) for dynamic, real-time presence information. {Position} follows FL Studio's active M:S:CS or B:S:T time-display mode.

Supported Versions

This tool utilizes AOB (Array of Bytes) scanning, allowing it to dynamically locate memory addresses even after minor software updates. It has been officially tested and verified on the following versions of FL Studio:

Important

While the tool is designed to be version-independent, internal memory structures can change. If you encounter issues or incorrect data with a specific build, please create an issue in this repository.

Configuration

All settings are stored in config.json in the project folder. Example:

{
  "discordAppId": "YOUR_APP_ID",
  "largeImageKey": "flstudio",
  "refreshInterval": 2,
  "defaultProjectName": "Untitled",
  "playingImageKey": "play",
  "stoppedImageKey": "stop",
  "presence": {
    "details": "{Project} | BPM: {BPM} | Pitch: {Pitch} | Metronome: {Metronome} | Mode: {Mode}",
    "state": "Playback: {Status} | Position: {Position}"
  }
}

Alternative Automatic RPC (DLL Proxy Method)

If you prefer not to run the tracker separately, you can enable Discord RPC automatically using the version.dll proxy:

1. Download version.dll from the releases page, or build FLDRPC/FLDRPC.vcxproj in Release|x64. The build generates both FLDRPC.exe and version.dll in FLDRPC/x64/Release.
2. Copy version.dll into the same folder as FL64.exe.
3. Optionally copy config.json into the same folder to customize the presence; otherwise the built-in defaults are used.
4. Launch FL Studio normally. The proxy forwards FL Studio's Windows Version API calls and starts Discord RPC automatically.

Important

This tool reads memory from a running FL Studio process.
