Working as an Audiology Trainer for HCP, I occasionally handle internal training. I train for hearing aid brands such as Signia, Widex, Rexton, and so on. Besides training, I also showcase special skills for sound demos, applying MIDI skills.

In April 2024, I recorded the Widex SmartRIC sound for the launch event. In June, a Signia IX live sound demo session was conducted for over 300 people at once, applying my MIDI system. In April 2025, I created a sound tournament session for competitor comparison, showcasing the Signia Pure C&G BCT IX product.
