Latest version of Synesthesia can be found here (Razer Sensa DevKit Github repository) – contains drivers, firmware and apps. Retail versions of the Razer Sensa HD Haptics do not need special drivers or firmware to work out of the box. (i.e. Razer Freyja, Razer Kraken V4 Pro)

Synesthesia app

The Synesthesia apps can be found in the Synesthesia folder of the repository. To avoid compatibility issues, do not unzip/copy the folder in the C:\Program Files (x86)\Interhaptics\Synesthesia folder (which is the normal path for the default app installed with Razer Synapse/Chroma). The executables can be found in the Release and ReleaseConsole folders.

Inside the folder there are also the following executables:

ChromaFakeClient\ChromaFakeClient.exe: simulates a Chroma Sensa enabled app and can send messages. The messages are loaded from the ChromaFakeClientData.txt file. Synesthesia must be started for the fake client to work.
SynesthesiaStop.exe: terminates the Synesthesia app if it’s active or in background.
HapticFolders\ : some sample folders containing haptic configuration file and the haps haptic effects to be played. (among them Hogwarts Legacy which is detailed in the following sections)
Release\ : folder containing release candidate version of synesthesia (no window/background process)
ReleaseConsole\ : folder containing console version of synesthesia. This version is able to automatically create a Haptic Folder just by listening to a Chroma Sensa enabled app’s external messages. To use the console version instead of the production version of Synesthesia/Haptic Service (included in Synapse 4) follow the steps below.
- Open Razer Synapse 4. Go to the Freyja Tab and press the Launch Sensa HD Haptics Button. Check that Haptic Source is Sensa HD Games. If it is Audio-to-Haptics switch it to Sensa HD Games.
- Open Task Manager. Look for the Synesthesia process or Haptic Service and close it.
- Open the Synesthesia Console and test the setup with ChromaFakeClient and the following commands load; active; play which will appear when starting the app.
