I guess it is up to the individual application designer. If the
application includes code to tweak the mixer directly then the volume
will be globally affected (I agree that is not good). Are you running
xmms with an alsa plugin? If not, xmms is probably using oss emulation
which is far simpler to control. Maybe PD is also running in OSS mode?
