Ardour sets linear mapping for some instrument parameters (here more info), that create drawbacks with some plugins that use logarithmic scale. So I think, Is possible remapping linear parameters with Lua?
The key difference between linear and logarithmic mapping is how values scale. With linear mapping, moving a parameter knob halfway gives you 50% of the value. With logarithmic mapping, the curve follows a logarithmic function, which is perceptually more natural for many parameters like volume, filters, and frequency.
I need help (Ardour Lua Task Force) for make a script for resolve that inconvenience and maybe create a solution for all community.
