Hi,

I do Gtk+-2.0 stylish coding. Any suggestions on changes on code are
appreciated?

I would love to get feedback for following code style:

http://git.savannah.nongnu.org/cgit/gsequencer.git/tree/ags/audio/ags_channel.c?h=2.0.x

My intension is to provide thread-safe properties and objects. Further reading:
