Parameter block layouts

4 Parameter Block Data Descriptions

This is a description of the parameter blocks transmitted using the bulk dump messages described in section 3.3. The names and byte offsets of each block parameter are given. The parameter value ranges are included in section 5. The following byte layout is the internal representation and not the MIDI byte format which is described in section 2.3.

4.1 Program Parameters

The first group of parameters through byte offset 92 describe one of the six possible voices in a program. This same structure is repeated with an additional offset of 92 for each of the other five voices. When the program has an option enabled (Pitch Table, Wave List or Drum Map), voices 5 and 6 are replaced with the option data. All of the global program parameters are at the bottom of this list. These parameter descriptions do not reflect the literal names shown on the TS display. Refer to the parameter definitions in section 5 for that information.

4.4 Single Sequence Dump Parameters

This message consists of the data from one sequence and the sequence header.

Byte Offset	Parameter Name
0	Sequence Data
n	Sequence Header

4.5 All Sequence Dump Parameters

This message consists of the data for all of the defined sequences and songs, 60 sequence and song headers, and the global sequencer parameters.

Byte Offset Parameter Name

Byte Offset	Parameter Name
0	Sequence Data Offsets - A table of 60 long word offsets (one for each sequence/song), with each entry containing the relative offset of the corresponding sequence/song data block from the beginning of the sequencer data block.
239	Sequence Data
n	Sequence Header Segment
n+header_size	Global Parameters

In an unexpanded system, the Sequence Data segment can contain a maximum of 131,072 bytes. In an expanded system (with SQX-70), the maximum is 393,216 bytes. The individual Sequence Header size is 338 bytes. The complete Sequence Header Segment is 20,408 bytes, which includes 60 headers, a table of pointers and some additional overhead. The Global Parameters segment is 38 bytes. Remember that all of this data is transmitted via MIDI as nybblized bytes, so the actual number of bytes transmitted is twice as large for each component of the dump. The size of the largest dump for an unexpanded TS in actual transmitted MIDI bytes may be calculated as follows:

Component	Actual Size (bytes)	Nybblized Size
SysEx Header	6
Data Pointer Table	480	240 nybblized
Sequence Data	262,144	131,072 nybblized
Sequence Headers	40,816	20,408 nybblized
Global Parameters	76	38 nybblized
End of Exclusive Length	1

Total Number of bytes sent: 303,543

This implies that an expanded system would have a maximum dump size that was larger by twice the difference in the Sequence Data segment size (i.e. two times 393,216 - 131,072 or 524,288 bytes). Therefore, the largest dump size for a fully expanded system would be a total of 827,811 MIDI bytes (or 1617 blocks).
