* -Changed to allow compilation and execution in 64-bit environments
* by using C99 standard intN_t and uintN_t types for MIDI structures,
* and formatting specifications like "PRId32" instead of "ld".
* 04 April 2015, L. Shustek, V1.7
* -Made friendlier to other compilers: import source of strlcpy and strlcat,
* fixed various type mismatches that the LCC compiler didn't fret about.
* Generate "const" for data initialization for compatibility with Arduino IDE v1.6.x.
* 23 January 2016, D. Blackketter, V1.8
* -Fix warnings and errors building on Mac OS X via "gcc miditones.c"

* 9t nn [vv] Start playing note nn on tone generator t. Generators are numbered
* starting with 0. The notes numbers are the MIDI numbers for the chromatic
