Peavey Transtube Series Operating Manual page 26

To initiate the transmission manually, hold the amp's TAP button and then press the MODULATION
Select button. The six Amp Model LED rings (Pre Gain through Reverb) should go off for a second
or two to verify the operation. When they come back on, the operation is done.
NOTE: The size of the System Exclusive preset dump is 1000 bytes.
If your recording device can send a request string to automate this operation, the string can be
found in the SysEx table below. Another cable will have to go from the Recorder's Out to the
Transformer's In for this to work. Sending that string to the Transformer will initiate the dump
operation.

Channel Messages
The Transformer will accept (and echo) the following channel messages when they are sent on its
MIDI Channel. (Values are shown in hexadecimal.):
• Program Change - Cx nn
• Bank Select - Bx 20 nn
• Main Volume - Bx 07 nn
NOTE: The Main Volume will be located after the preamp and EQ and before the time-based
effects.
Other channel messages will be echoed to the MIDI Out, but will not affect the Transformer.
The Transformer will generate the following channel messages on its MIDI Channel:
• Program Change (as shown above) - whenever a preset change is initiated by front panel or
PFC4.
• Bank Select (as shown above) - whenever the MATRIX bank is toggled from/to Factory to/from
User.
System Common and System Real Time Messages
The Transformer will echo these messages to the MIDI Out when received. None will be generated
by the Transformer.
System Exclusive Messages
The Transformer is equipped with an extensive MIDI SysEx implementation. In addition to simple
preset dumps and preset sharing via the Internet this enables the amp to be programmed remotely
by a computer program or hardware editor like the Peavey PC1600X.
All of the Transformer's SysEx messages start with a common header and end with an End of
Sysex [EOX] byte. The table below shows the "unique" section (including the command and optional
data) of each message that falls between the header and the EOX.
Here is the common part, along with descriptions of each byte's purpose:
F0 - Start of SysEx [SOX]
00
00
1B - Peavey Manufacturer ID = 00 00 1B
10 - Transformer Product ID
00 - Reserved for future use (keep fixed at zero)
CMD - Command byte that defines which SysEx message it is
<data>- Optional data
F7 - End of SysEx [EOX]
