 338  *      Midi controller numbers
 339  *******************************************
 340  * Controllers 0 to 31 (0x00 to 0x1f) and
 341  * 32 to 63 (0x20 to 0x3f) are continuous
 342  * controllers.
 343  * In the MIDI 1.0 these controllers are sent using
 344  * two messages. Controller numbers 0 to 31 are used
 345  * to send the LSB and the controller numbers 32 to 63
 346  * are for the LSB.
 347  *
 348  * This driver uses just the numbers 0 to 31 to store both
 349  * the LSB and MSB. The controller value is a unsigned short
 350  * and it's valid range is between 0 and 16383 (0x0000 to 0x3fff).
 351  * The driver sends the controller value using two messages when
 352  * necessary.
