Package: audacity Version: 2.1.2-1+b1 Severity: minor Dear Maintainer,
In the settings window for LADSPA effects, the sliders do not move to negative integers. If, for example, an integer option ranges from -3 to 3 (inclusive), the slider will only move within one half of the bar. What is interesting is that negative values can still be entered manually, and the slider will even move to the appropriate position in the negative part! But trying to adjust the slider will cause it to jump back to the 0 position. Also, the lower-bound label for the slider is incorrect when negative integers are involved: It is one greater than the true lower bound. So, if the range were from -3 to 3, the lower-bound label would be -2. However, the slider seems to behave as if the lower bound is correct. I first discovered these issues while using Tom Baran's Autotalent plugin (packaged as "autotalent"), so that may be used to reproduce these issues. I have also attached a test plugin which may help. Thank you for your consideration.
