Message Format
The MIDI Show Control message format is given below:
F0 7F <ID> 02 <fmt> <cmd> <Tmsb> <Tlsb> 00 <Pmod> 00 <CLh> <CLt> <CLo> F7
The following table explains each of the optional HEX bytes in this
message:
Data Byte Entry/Description
<ID> unit a 9 (7FH is a wild card for all units)
<fmt> = 10 (sound)
= 30 (video)
= 7F (wild card)
(Note: since the Binloop responds to both the ‘sound’ and ‘video’
parameter equally, normally the ‘wild card’ is used here)
<cmd> = 01 (to Play Synchronized)
= 02 (to Stop Sound)
= 03 (to Play Unsynchronized)
= 04 (to Still Video – still frame on screen)
= 05 (to Pause Video – video output goes black)
= 15 (to Start SMPTE)**
= 16 (to Idle SMPTE)**
= 17 (to Reset SMPTE)**
= 18 (to Pause SMPTE)**
Tmsb Tlsb* = track ID 30 30 - 31 35 for Reproducers 1 through 16 respectively
= group ID 35 30 - 36 32 for Groups 1 through 13 respectively
= all tracks ID 36 33 for accessing all Reproducers in the Binloop
Pmod = 31 (Normal Play)
= 34 (Independent Play – Right Channel)
= 37 (Independent Play – Left Channel)
CLh CLt CLo* = file number 30 30 31 - 35 31 31 for file numbers 1 through 511
respectively
= file number 35 31 33 - 39 39 39 for looping file numbers 1 - 487
respectively
*Although they are showed in this table in hexadecimal form, both the
Track and Clip are ASCII numbers. 2 Bytes make up the Track number,
and 3 bytes make up the Clip number.
**SMPTE commands do not require the Track or Clip bytes.
