I find this a very good feature actually, but I think the solution should be different.
I think we should allow a button in the general tab on each channel or perhaps just one button/command from the menu that allows you to half all channel volumes, so you can then change the volume on your channel. Even better would be a 2nd option to normalise all channel volumes, so that it calculates which channel volume is closest to 64, and then increases all channels by that amount. Say: your highest channel is 48, then you need to add 16 to each channel to make it sound good again. Or if its better (couldn't really find out) to increase respectivelly (eg, how much % is it: 25%, then increase all by 25%.
