Crane is a dedicated control board designed as a crucial component of a larger microtonal piano system under development. It features an 80 MHz Cortex-M microcontroller for efficient processing, alongside a 2.4-inch LCD display with a 240×320 resolution for clear, user-friendly interactions. The board includes 12 responsive buttons, including a reset button, allowing users to easily navigate through various functions. One of its key features is the ability to toggle between boot mode and application mode, enabling seamless firmware updates and programming without the need for external tools.
The primary function of Crane is to serve as the user interface for the microtonal piano, enabling a wide range of configurations. Users can fine-tune key pitch settings, adjust temperament, select different instrument sounds, and manage various other customizations, all through an intuitive interface. By providing this level of control, Crane allows musicians to explore new tuning systems and sonic possibilities, making it an essential part of the piano’s innovative design. Additionally, its efficient design ensures reliable performance and smooth operation, enhancing the overall user experience.
