Linux-cpp-lisp / cpp-posix-errors.cpp
Created May 24, 2012 13:20
A few small macros used to simplify error handling in C++ code that uses POSIX and UNIX system calls. Depends on an exception class UNIXError, which just happens to have an argument-less constructor that will get an error string based on the current value
#define ERR(__statment, __retVar) ((__retVar=(__statment))==-1 ? throw UNIXError() : (__retVar))
#define ERR_ERRVAL(__statment, __retVar, __errval) (((__retVar)=(__statment))==(__errval) ? throw UNIXError() : (__retVar))

A set of classes used to simplify error handling with POSIX and UNIX functions in C++ programs. Header and `.cpp` files. Contains a class that works with `errno` errors, and one that works with `getaddrinfo` errors.

Linux-cpp-lisp / num_range_shrink.c
Created January 6, 2014 19:39
A little function to take a value in the range 0-x and convert them to values in a different, smaller range.
unsigned int num_range_shrink(unsigned int orig, unsigned int old_limit, unsigned int new_upper) {
float interval = old_limit / new_upper;
for(int i = 1; i <= new_upper; i++) {
if(orig < i*interval) {
return i-1;
}
}
return 0;

MIDI behavior and notes for the Yamaha DTXPLORER drum trigger module.

MIDI Map for Yamaha DTXPLORER Drum Brain

Note: The DTXPLORER has some odd MIDI behaviour. For example, when a drum is triggered, a Note On is sent with the velocity, and moments later, another Note On is sent with a velocity of zero as some kind of note off.
