Abstract
A rotary fader apparatus includes a fader control knob that is directly attached to the rotor of a non-contact electrical motor. The apparatus may produce a fade effect based on the rotational position of the fader control knob and may be automated through signals to the motor. Such a rotary fader apparatus may be used, for example, in audio mixing applications to provide automated or manual rotary control of track fading. The motor may also be used to alter the feel of the movement of the fader control knob and/or provide tactile feedback in response to mixing parameters or signal properties.
Claims18
An apparatus comprising:
- a control knob moveable to a plurality of positions, each of the plurality of positions associated with a control function;
- and
- a control circuitry configured to modify an input signal based upon the control function associated with a detected position from the plurality of control positions,
- wherein the control knob is coupled to a rotor and a stator, wherein the stator is moveable to allow the control knob to move between the plurality of positions.
An apparatus comprising:
- a control knob configured to rotate in a clockwise direction and an anticlockwise direction, each of the clockwise direction and the anticlockwise direction being assigned at least one rotational position, wherein each of the at least one rotational position is associated with a control function;
- and
- a control circuitry configured to:
- receive an input signal;
- assign one of the clockwise direction or the anticlockwise direction to the input signal;
- detect movement of the control knob to a detected position in the assigned one of the clockwise direction or the anticlockwise direction;
- and
- modify a property of the input signal based on the control function associated with the detected position;
- and
- wherein the control knob is coupled to a rotor and a stator, wherein the stator is moveable to allow the control knob to move between the at least one rotational position.
A method comprising:
- receiving, by a rotary fader apparatus, at least one input signal, the rotary fader apparatus comprising a control knob moveable to a plurality of positions, wherein each of the plurality of positions is associated with a control function;
- detecting, by the rotary fader apparatus, a detected position from the plurality of positions;
- and
- modifying, by the rotary fader apparatus, the at least one input signal based upon the control function associated with the detected position for generating an output signal,
- wherein the control knob is coupled to a rotor and a stator, and wherein the stator is moveable to allow the control knob to move between the plurality of positions.
