Thanks a lot for all explanation. Things are much clearer now.

I guess the simpler solution right now if to implement a blocking 
call for incoming Midi events and use a Lisp created thread to read 
them.

Do you plan to implement the get_tcr() stuff and all what would be 
needed to implement the "complex" solution at some point?

Thanks
