hey there,

i wrote an extra routine for requesting some special 
parameters so that there are never too many parameters 
requested at once.
its not good to just resize the alsa queue. its not really 
a solution.
i am sure that, when i remove the mutexes and gtk stuff 
from the midi_callback, the thread wont block.
but what can i do? i want the gui to update as quickly as 
possible.
write another queue which is used by the midi_callback to 
push data into it and add another thread that reads from 
it?
