I wonder if it would be interesting to include a small utility I wrote
assisted by a friend of mine (Paolo Masetti) to convert MIDI files into
LegOs C code: since then all of our robots are equipped with a subroutine
generated by this utility!
It's standard C++ compiled for a win32 console application, but should
compile ok also in many other enviroments without changes.
We also did an attempt to a WAV to RCX conversion with poor results, but
during the development of the program we discovered that some of the note
constants in dsound.c aren't very accurate (usually off by 1), but for high
frequencies the wrong computation of these dividers leads to an error of
many Hertz!
BTW I'd like the size of this array of constants could be extended to 128,
in order to cover all possible midi notes.
You can find the two executables (Windows console only) at
www.aga.it/~guy/lego.htm but, if someone cares, I can provide the sources
too.
Ciao, Guido
