Abstract
For a parameter used by a tone generator unit to generate an audio signal, type of an effect to be given to the audio signal and degree of the effect to be given to the audio signal are set according to an operation of a panel strip which functions as a combination of an increase control decrease controls with an upper cursor part and a lower cursor part. This setting is made so that when an operation to further decrease the degree of the effect to be given to less than zero is detected, the type of the effect to be given to the audio signal is changed.
Claims18
A parameter controller configured to control a parameter used by a tone generator unit to generate an audio signal, the parameter controller comprising
- a controller configured to set, according to an operation of one increase and decrease control or one combination of an increase control and a decrease control, type of an effect to be given to the audio signal and degree of the effect of the type to be given to the audio signal,
- wherein the controller is configured to change, when the controller detects an operation to further decrease the degree of the effect to be given to the audio signal to less than zero, the type of the effect to be given to the audio signal.
A method for controlling a parameter used by a tone generator unit to generate an audio signal, the method comprising:
- setting, according to an operation of one increase and decrease control or one combination of an increase control and a decrease control, type of an effect to be given to the audio signal and degree of the effect of the type to be given to the audio signal;
- and
- changing the type of the effect to be given to the audio signal when an operation to further decrease the degree of the effect to be given to the audio signal to less than zero is detected.
