envy24control: enhanced mapping of midi controller
From: Dirk Jagdmann <doj@cubic.org> Hello, this patch adds a command line option to select a better mapping from midi controller values to dB sliders. The default stays as a linear mapping, which has the disadvantage, that a sensible area to adjust your volume (which ist mostly in the range of 0..-12dB) is in the upper 1/10th of your midi controller. This patch adds a map, which consists of two linear functions, so that the upper half of your midi controller controls values from 0..-12dB, the lower half then controls -13..-96dB.
