Reading through the docs, and things on the net, I found a way to set up a softvol control for it in alsa, so when I adjust its volume, it only changes the volume for moc. Everything went well, except, I can't adjust the volume from within the moc app, which should be possible because you can set the alsa device and mixer in the ~/.moc/config file.
> It is using the right device, and amixer sset Mocmaster 50% sets the volume. It's just the in program controls that fail. When moc starts, it gives this error:
> ALSA lib dlmisc.c:254:(snd1_dlobj_cache_get) Cannot open shared library /usr/lib/alsa-lib/libasound_module_ctl_softvol.so
> This makes me think that either a plugin is missing from alsa-plugins, or maybe moc is using an outdated way to change its volume. However, if the alsa controls are set to their defaults, the volume works fine, but it lowers the volume on the whole system.

my only guess would be to install this:

https://aur.archlinux.org/packages/asoundpp-git/

as i see moc uses speex. just a guess though.
