Fixed footer controller  

A fixed footer controller is a user interface element that remains visible at the bottom of a webpage or application screen, even when the user scrolls through the content. This controller typically contains various buttons or controls that allow the user to interact with the content or perform specific actions, such as playing or pausing a video, adjusting the volume, looping  complex parts of the song, or adding your favourite song  to the jamlist .

Overall, a fixed footer controller is a valuable and practical user interface element that can enhance the usability of your jamming experience.
