Obtaining Raw Analog Inputs

Greetings, I recently purchased the Razer Huntsman V2 Analog Keyboard and I am hoping to make use of its analog controls in Minecraft version 1.0. However, I have discovered that the limitations of the game itself prevents me from achieving this goal by making use of only the settings in Synapse. I am therefore interested in modding Minecraft to incorporate these capabilities and I was wondering if there is a way to obtain the linear key press data, as displayed in Synapse. If I had access to these values I believe the implementation would be quite simplistic. I would initially be starting with Minecraft modding through Java, but would hope to expand this to other games that I play in the future. I have tried searching online and can't seem to find anything on this subject other than an implementation for Cyberpunk. Does a connection to the "raw" inputs exist and how would I go about obtaining it in a programming language? Thank you for your time and responses.
