1167 | * SEQ_SYSEX permits sending of sysex messages. (It may look that it permits | |
1168 | * sending any MIDI bytes but it's absolutely not possible. Trying to do | |
1169 | * so _will_ cause problems with MPU401 intelligent mode). | |
1170 | * | |
1171 | * Sysex messages are sent in blocks of 1 to 6 bytes. Longer messages must be | |
1172 | * sent by calling SEQ_SYSEX() several times (there must be no other events | |
1173 | * between them). First sysex fragment must have 0xf0 in the first byte | |
1174 | * and the last byte (buf[len-1] of the last fragment must be 0xf7. No byte | |
1175 | * between these sysex start and end markers cannot be larger than 0x7f. Also | |
1176 | * lengths of each fragments (except the last one) must be 6. | |
1177 | * | |
1178 | * Breaking the above rules may work with some MIDI ports but is likely to | |
1179 | * cause fatal problems with some other devices (such as MPU401). | |
