Is it possible to make a pp act exponential in the host application?
For an example look at the cutoff parameter of the standard Logic low pass filter. When you set the slider to half of the range, the displayed value is approximately 650 Hz although the total range is from 20 to 20000 Hz.
As far as I know it is not possible to make a pluggo plugin act this way. Of course it is possible to scale the value after it is sent from the host application to the plugin, but in that case the displayed value wouldn't match the actual value. Is there a way to work around this?
