The present application discloses systems and methods for displaying and operating a user interface having one or more channel group controllers corresponding to one or more groups of hearing prosthesis channels. The hearing prosthesis may be configured to generate a plurality of signals via a plurality of channels based on a channel profile. The channel profile may define at least one intensity level for each channel. In operation, the user interface may be configured to instruct the hearing prosthesis to change the channel profile of the plurality of channels in response to receiving an input via one of the channel group controllers. The user interface may be used to fit a hearing prosthesis to a recipient. In one embodiment, an initial channel profile may be automatically determined, and the prosthesis channel profile may be adjusted by changing a representative intensity level corresponding to the channel profile.
