See the list a few weeks back where I discussed exactly this problem.
Current thinking is that we should have a second executable that provides
a GUI and that could communicate with the DSP part, probably via OSC.
I think that the best option is that the DSP .so provides a function that
can be called to create the GUI. So you could link the two parts in
whatever way you want, stdin<->stdout would be OK I guess.
If you don't want to mess with GUIs then go for a config file which lists
a set of samples, and an int hinted port that specifies which sample to
play.
