+ * Modify this file to suit the needs of your particular system.

+ * EAS_MAX_FILE_HANDLES sets the maximum number of MIDI streams within

+ * EAS_HW_FILE is a structure to support the file I/O functions. It
+ * comprises the base memory pointer, the file read pointer, and
+ * the dup flag, which when sets, indicates that the file handle has
+ * been duplicated. If your system uses in-memory resources, you
+ * can eliminate the duplicate handle logic, and simply copy the
