Millennium Enterprises Stereo150 - Manual (Page 98)

Pitch Bend : Pitch Bend information is a higher resolution controller that is not supported in Johnson Amplification products, due to the
density of the information and the resources needed to process it properly. Many MIDI control products offer the ability to map Pitch Bend
to normal Continuous Controllers if a user wanted to control a parameter with a device such as a Pitch Bend Wheel.
General Format
The general format for the System Exclusive information is as follows (note: all SysEx values are displayed in Hexadecimal format, along with
this symbol (h) for clarification):
Hex Value Definition
F0(h) System Exclusive ‘Begin Message’ byte
00(h)
00(h)
Manufacturer’s ID Number (Johnson Amplification)
10(h)
0n(h) n = Unit’s Device or SysEx Channel number (minus one)
e.g.
00(h) is device or SysEx Ch 1
01(h) is device or SysEx Ch 2 etc...
0F(h) is device or SysEx Ch 16
dd dd = device ID number 4A(h) identifies the Millennium
pp pp = Procedure number. The different procedure’s names and general formats are
described in the Procedures Section.
dd(1)1, dd(1)2......dd(n)1, dd(n)2
dd = Data as needed by procedures. Since the standard MMA MIDI Specification reserves 80(h)
through FF(h) (decimal numbers 128 through 255) for specific commands, a split byte format is
adopted for all data communication in this SysEx implementation. dd(n)2 denotes the 1st
through 7th bits of the nth byte and dd(n)1 denotes th 8th bit of the nth byte. Note: All data that
is requested or received, is in split byte format unless noted otherwise.
F7(h) System Exclusive ‘End Message’ byte
Procedures
In the following section, SYS_HEAD refers to a valid System Exclusive header. The System Exclusive header starts with the System Exclusive
status byte, and includes all bytes through the Johnson Amplification device type. F7(h) is the System Exclusive ‘Message End’ byte. All SysEx
numbers in the format definition of each procedure are given as hexadecimal values, along with this symbol (h) for clarification. Binary
numbers are identified with this symbol (b).
