Re: Recording widget motion

["Samuel Cormier-Iijima" <sciyoshi gmail com>]

This is for music editing software I'm thinking about writing.
Basically, the user should be able to "record" the volume during
playback by sliding the GtkHScale around. When he plays it back the
next time, the volume should change according to the way he recorded
it (i.e. it'll wiggle around by itself during the song playback). If
you use Reason 3, you'll know what I mean. Anyways, I've found out a
(unclean) way to do this, and I'm looking into using GStreamer and
GstController's for this. Still, any links or pointers would be
appreciated.
