An exemplary sound processor included in a cochlear implant system associated with a patient 1) receives, from a fitting system while the sound processor is communicatively coupled to the fitting system, a command that sets a control parameter associated with the cochlear implant system to an initial value and data representative of a target value associated with the control parameter, 2) detects a decoupling of the sound processor from the fitting system, the decoupling resulting in the sound processor being in a non-fitting state, and 3) gradually adjusts, while the sound processor is in the non-fitting state, the control parameter from the initial value towards the target value in accordance with an adaption time course associated with the control parameter. Corresponding systems and methods are also disclosed.
