PCM 80 Version 1.10 MIDI Implementation Details
Lexicon
0x00 System Configuration Response
This response is transmitted by the PCM 80 to a remote device when requested. It is ignored by the PCM
80. Note that this is not a Setup Dump — it is purely informational.
Byte # Byte Value Description Notes
1 F0 SysEx ID
2 06 Lexicon ID
3 07 PCM 80 ID
4 0iii iiii Device ID
5 0x0 Configuration Data
6 0iii iiii Major Version # This is the version number that appears to the left of the decimal
point on the the integer portion of the power up display.
7 0iii iiii Minor Version # This is the version number that appears to the right of the decimal
point on the fractional portion of the power up display. On the front
panel this may be displayed as a 2-character value with a leading
zero. For example, a minor revison of 1 will appear as x.01. A minor
revision of 10 will appear as x.10
8-15 0iii iiii 8 Byte Time string Time of the code build in ASCII format xx:yy:zz
(Hours:Minutes:Seconds)
16-26 0iii iiii 11 Byte Date string Date of the code build in ASCII format: xxx:yy:zzzz
(Month:Day:Year)
27-34 0000 iiii 56000 memory page count
4-byte value (nibble-ized) Number of pages (64K words/page) of memory available to the
Motorola 56002 processor. The number of pages in a standard
PCM 80 is 4. Memory can be expanded using SIMM memory.
35-148 0iii iiii 114 Byte Bank information
(Space for 57 banks) Indexed by bank, 2 characters/bank. First character=bank size.
(0=bank not present.) A non-zero in the second byte indicates that
the bank is a non-writeable preset bank.
149 0n Card Present non-zero if present
150 0n Card Write Protect non-zero if protected
151 0iii iiii Card Version Indicates the version of the card directory structure. This should be
ignored if the Card Present bit is not set.
152 0iii iiii Card Type Types are:
0x00=ROM (holds algorithms or presets)
0x01=RAM (holds user effects, maps, setups and chains)
0x80=Bootable Diagnostics card.
This should be ignored if the Card Present bit is not set.
153-162 0iii iiii 10 Byte Name string for card This should be ignored if the Card Present bit is not set.
163 0iii iiii Page count Indicates the amount of memory available on the card. 1 page=64K.
For example, 0x10 indicates 1 megabyte. This should be ignored if
the Card Present bit is not set.
164 0iii iiii Count of algorithms online Number of valid algorithm IDs in the array beginning at byte 165.
These are the algorithms currently available to the system and
include internal algorithms plus any algorithms loaded from card.
Algorithms for any card not loaded into the system will not appear
here.
165-228 0iii iiii 64 Byte List of algorithm IDs Only count from byte 164 is valid.
229 0iii iiii Current User Interface Mode 0=Control; 1=Tempo; 2=Edit; 3=Program; 4=Register. Mode and
submode are purely informational and do not affect PCM 80 ability
to respond to MIDI.
230 0iii iiii User interface in a Submode 0=False; 1=True. A submode is defined as a state of the machine
that is different from that caused by pressing Control, Tempo, Edit,
Program Banks or Register Banks. This includes any of the dialog
modes such as saving an Effect, etc.
231 0iii iiii Compare mode 0=Off, 1=On
232 0iii iiii Bypass 0=Off, 1=On
