  • Patent number: 5763800
    Abstract: An audio data format in which an instrument is described using a combination of sound samples and articulation instructions which determine modifications made to the sound sample is provided. The instruments form a first, initial layer, with a second layer having presets which can user defined to provide additional articulation instructions which can modify the articulation instructions at the instrument level. The articulation instructions are specified using various parameters. The present invention provides a format in which all of the parameters are specified in units which relate to a physical phenomena, and thus are not tied to any particular machine for creating or playing the audio samples. The articulation parameters include generators and modulators, which provide a connection between a real-time signal and a generator. The parameter units are specified in perceptually additive units, to make the data portable and easily edited.

  • Patent number: 3999442
    Abstract: A control device having a support and a first selector member rotatably carried by the support. A second selector member is rotatably carried by the support and is axially movable relative to the support and the first selector member. The selector members are coupled together in a manner to cause the first selector member to rotate in unison with the second selector member when the second selector member is rotated. A pair of spaced spring members are disposed between and respectively engage the selector members to tend to maintain the second selector member axially away from the first selector member. The first selector member has a cylindrical part extending therefrom and the second selector member has a C-shaped shaft rotatably disposed against the cylindrical part of the first selector member.
