LUSP Data Type Label Message (5)

LUSP Class Label Message (05 hex)
This message allows you to get a string describing the Class at a given control level. This message was included to simplify navigation of the control tree when the controlling system has limited memory available. The string returned is the same as the "name" field of the Class description message.

Byte # Value HEX Description Notes

1 F0 Sysex ID (Start)

2 06 Lexicon ID

3 0bbb bbbb Product ID

4 0bbb bbbb Device ID 0-127

5 05 Class Label Message type

6-9 0n Number of characters This is the number of chars (bytes) in the string

10-x 0n Class Label String This is the actual string (nibblized) so it is the "Number of characters" times 2 long

-- 0n Number of control levels (2 bytes) This field defines how many control levels are used in the Class's address. This is a 16 bit field so the address can have up to 64k digits (control levels)

-- 0n Control level 0 (A) (address) (2 bytes) This is the first control level. It defines the level 0 (A) control address of the Class. The control level addresses are 16 bit fields so the control addresses can be 64k deep. Note that letters are used to help differentiate between levels and their values.

-- 0n Control level 1 (B) (address) (2 bytes) same as previous

-- 0n Control level 2 (C) (address) (2 bytes) same as previous

-- 0n --- up to Control level 65535 same as previous

--- 0n Checksum This is an optional "Checksum" field. The checksum is the low 7 bits of the sum of all preceeding bytes in the message following the "Message Type".

0n - Number of Control Levels (hi nib) (Nibble 4 of argument)
0n - Control Level 0 (A) (lo nib) (Nibble 5 of argument)
0n - Control Level A (lo mid nib) (Nibble 6 of argument)
0n - Control Level A (hi mid nib) (Nibble 7 of argument)
