Re: [linux-audio-dev] GUIless friendly applications

Things are going in the right direction, the audio code is now seperate from the rest of the app at least. You can currently (from CVS) run ssm without a GUI at all, it just loads a patch and plays it until you hit ctrl-c. I intended this for using midi only control (but you still have to use the GUI to build the patch in the first place of course). I am interested in doing a GUIless interface for ssm, and I have been thinking about it for some time. I think making a text based patch builder for ssm would be fairly easy, i.e "connect oscillatorA.output to envelopeB.audio_in" but changing the modules parameters in realtime might be a bit more difficult. The real problem, as you noticed is that the plugins have all the fltk code built in :( (a design decision for other very GUI-centric reasons). However, a side effect of having to make the code threadsafe is that all control data from the gui widgets now have to be passed though a "channelhandler" class which deals with all the mutexes etc. These channels even have plain text names that make sense in the context of the plugin. So I think it may be possible to write another app, which is compatible with ssm's plugins and redirects (by overloading the channelhander) the control data from a keyboard based interface. In theory :) Another possibility that might make more sense (something else I've been thinking about) is a LADSPA only modular synth - as LADSPA plugins are much less bound to a GUI than ssm's the interface could be much more textual. I'll think more about the possibilities of modifing ssm, but the bad news is that I have a todo list pages long at the moment :( :( :( Cheers, dave
