Well, after yesterday’s design post I have started implementing it in Jokosher. Currently the dialog pops up and you can select a LADSPA effect, add it to the instrument and configure the effect settings. The settings are mostly saved at the moment, although there are still some bugs, which I suspect are to do with data types or range problems.
So, the LADSPA support is largely ready in Jokosher. When a friendly GStreamer developer fixes the bugs in the LADSPA bridge, I can test to see that it works fine. 🙂
