I will shrink the meters slightly, simply to align better with the slider scales. Uh, if you don't mind, I actually want to increase the mixer sliders to around -60dB, instead of -48dB which I think may be a wee bit too high. The meters will only be as long as the -48dB mark, but the sliders will be longer, if it doesn't look too bad and there's enough room.

I totally neglected the mouse wheel! (I use a trackball). Will investigate to make sure wheel works OK. I am aware of the issues when clicking on a slider, or moving it with the mouse. I'm working on it. Part of the problem with the sliders is that they operate with floating point. If you click on a slider it outputs a fractional value even if it's already on an integer value, especially when the slider is stretched. When you click on a slider, it sometimes goes back one fractional step, which may be enough to cause it to go back one integer step. I need to round() some of the values at several places in my code, but when I tried it I got a pre-c99 compiler warning about warning: incompatible implicit declaration of built-in function ‘round’. So I left it alone. Perhaps with your -lm fix this will go away, or else we can just modernize the build as 'c99 compatible'. With proper rounding some of these issues might go away. > > > One more thing: Because of my use of gtk_adjustment_get_page_increment() > > and friends, which require gtk+ 2.14, I think it may be necessary to > > release this as a separate program than envy24control. > > There may be people out there with old setups who need the old one. > > The ALSA folks may not like replacing the old one with mudita24 for > > that reason. > > Seems like there should be a way for their build system to handle > skipping programs that use gtk2 if only gtk1 available ... at least > for the myriad packages in > alsa-tools "Specialist tools for ALSA" -- which might also be a > perfectly appropriate place to put a latest-gtk2-using tool providing > special control to a specific set of cards.

I'm not sure what the correct course of action is. Let's see what the ALSA community recommends. I was only thinking of folks with old distros+gtk who might want to use mudita24. (Alas, that might not be possible.) That's why completely replacing envy24control with mudita24 worried me a bit. This has been an interesting summer project! Mudita24 is an important app, as you say, especially for those with expensive professional envy24-based gear. The meters, the markings, the feel. Good!
