324
 * Any number of events can be written with a write call. There
325
 * is a set of macros for sending these events. Use these macros if you
326
 * want to maximize portability of your program.
327
 *
328
 * Events SEQ_WAIT, SEQ_MIDIPUTC and SEQ_ECHO. Are also input events.
329
 * (All input events are currently 4 bytes long. Be prepared to support
330
 * 8 byte events also. If you receive any event having first byte >= 128,
331
 * it's a 8 byte event.
332
 *
333
 * The events are documented at the end of this file.
334
 *
335
 * Normal events (4 bytes)
336
 * There is also a 8 byte version of most of the 4 byte events. The
337
 * 8 byte one is recommended.
