Hi! I am working on a GUI designing tool for LADSPA/DSSI around Qt designer. The idea is to extend the DSSI gui concept to LADSPA (OSC control included) and provide a skinnable tool to manually design GUIs. I plan also to include some user interaction enhancements. You can see some fancy concept diagram here http://flam.sourceforge.net/ There is some code behind it, too, but at the moment its structure is fluctuating and no effort of autotoolization/sconification has been done. There is a working skinnable slider and flamwizard is half finished. The skinnability will by provided by means of QStyle plugins. You can have very minimalistic depictions of the UI gadgets or hardware panel simulations. The GUI viewer, called flammer, will allow for loading/saving presets and load alternate GUI layouts for a given plugin at runtime. Now I have a doubt about LADSPA_HINT_SAMPLE_RATE. To effectively incorporate this hinting in the GUI, the host must have some means of letting know the GUI what the current sample rate is. Is there any standard procedure for achieving this? Comments, ideas, please? Cheers, Luis
