You would need to check the gstreamer/docs/random/moving-plugins checklist to see whether it is ready. I think there are some open feature requests. One thing I have somewhere on my todo list is to allow the application to set the jack-client. This would help to have a pesistent jack connection and is needed of one wants to e.g. support jack midi in addition or handling the jack transport control. </blockquote><div> Stefan, could you put your TODO in gst-plugins-bad/ext/jack?

Still this makes no reverb. Adding some delay variants would be nice (a multitap delay, a cross-delays, a cross-delays with filters in the feedback loop, ...). And a real reverb would be nice (could e.g. be build on freeverb). Right now we can use this via ladspa bridge in gstreamer. Maybe both suggestions could be joined as a "creative audio" GSoC bundle. Not sure what others think.
