Hi all The new GSequencer API in its version 0.7.1 is available for now at: http://gsequencer.org/api/ags/ Thought many things still need to implemented, here's a brief list of what I intend to achieve: * DSSI support * LV2 support * JACK midi input and audio output * Automation editor * Undo / Redo Are you interested in supporting GSequencer, feel free to contact me. Note ABI might probably change. So it's recommended to install the libraries in a private context. cheers, Joël
