Functions
- ControlSpec.new (min, max, warp, step, default, units, quantum, wrap)
-
constructor
Parameters:
- min number the minimum value of the output range
- max number the maximum value of the output range
- warp string ('exp', 'db', 'lin') a shaping option for incoming data (default is 'lin')
- step number quantization value. output will be rounded to a multiple of step
- default number a default value for when no value has been set
- units string an indicator for the unit of measure the data represents
- quantum number input quantization value. adjustments are made by this fraction of the range
- wrap boolean true to wrap around on overflow rather than clamping
Returns:
-
ControlSpec
- ControlSpec.def (args)
-
