For those following along, that link should have been:
http://www.teuton.org/~gabriel/code/midixlate-0.1.0.tar.bz2

I got this error compiling:

 /usr/local/midixlate-0.1.0> make
g++ -ggdb -fno-inline -fno-default-inline -c -o main.o main.cpp
main.cpp: In member function int MidiTranslate::process(jack_nframes_t):
main.cpp:279: error: memcpy was not declared in this scope

Here's my g++ version:

/usr/local/midixlate-0.1.0> g++ --version
g++ (SUSE Linux) 4.4.1 [gcc-4_4-branch revision 150839]

Googling shows lots of reports of that error. This include fixed it:

I did my mappings and ran it. Looking at the code, I'm not exactly
sure what the intention of the output of a successful translation is -
stdout, midi file etc? I don't see anything happening, though
"aseqdump --port=24:0" shows data comming in. Here's my qjackctl
config:

Looks very promising and could likely be exactly what I need, once I
figure out how to get its output.

Thanks!
