Abstract
A parameter setting apparatus is provided in an electronic music instrument for editing a configure of parameters in accordance with a manipulation amount to set a tone generator which creates a desired timbre of musical tones upon setting. In the apparatus, a first memory device stores a first subset of parameters containing a Boolean parameter having a first Boolean value and a numerical parameter having a first numerical value. A second memory device stores a second subset of parameters containing the Boolean parameter having a second Boolean value and the numerical parameter having a second numerical value. An operating device provides a manipulation amount for editing parameters. An interpolating device interpolates the first numerical value and the second numerical value in accordance with the manipulation amount to determine an edited numerical value of the numerical parameter. A selecting device selects one of the first Boolean value and the second Boolean value in accordance with the manipulation amount to determine an edited Boolean value of the Boolean parameter. A setting device configure the tone generator with the set of parameters containing the numerical parameter having the edited numerical value and the Boolean parameter having the edited Boolean value.
