The second column indicates the "Value" of the particular field, usually in hex (sometimes in binary). In some cases the value is fixed number ("Lexicon ID") while others can change from message to message. "Values" that can change are represented using a combination of numbers and letters. Binary numbers, for instance, are represented using the lower case letter 'b' for each variable bit in the value ("Device ID: 0bbb bbbb. The 'b's can be '1's or '0's). Hex numbers which can use different numbers in the lower nibble are represented with lower case letter 'n's (Major Version: 0n. The 'n' can be any hex number between 0 and F).
Although only a single "0n" is indicated in the "Value" column for certain fields, these fields will often consist of multiple bytes (each of which uses the format: 0n). This is due, in part, to the nibblizing scheme used in this SysEx implementation (see the previous section), but also due to capability of a single field to describe a group of more than 1 byte (strings, for example). In these cases, the "Description" column usually indicates how many bytes of actual data are contained in the field. I say "actual" data because all of the data bytes following the header (bytes 1-5) are in the "nibblized" format: each byte is broken up into 2 separate bytes. The first byte contains the low nibble and the second byte contains the high nibble. The "number of bytes" indicated in this column, therefor, is for the data after it has been de-nibblized.
