18. UTILITY
Among the many effect algorithms of the BURN there are two, at the end of the list, considered UTILITY. The first, called
PASS THRU, is a digital stereo bypass, it means that the stereo signal coming into the DSP processor is led to the outputs
with no change. This could be useful if you want to take advantage of just the tube distortion of the BURN, present only
at the left channel, without applying any other effects.
The second UTILITY effect is called MUTE and does nothing but mute the output. This could be useful in case you want
to mute an instrument through a foot pedal or a Program Change command sent via MIDI.
18.1. SHORTCUTS
There are some shortcuts that allow you to perform some operations faster. For example, to save a presets without
necessarily reaching the [PRESET] WRITE, just hold down the EDIT/ENTER button for at least 2 seconds. The preset will
be saved in the current location, overwriting the existing data.
When you change the value of a parameter, you can return to the original value of the preset by pressing once
EDIT/ENTER when you are in EDIT mode at level 2 (change of a parameter). For some global settings, such as the MIDI
channel, this operation calls the default value.
When some preset parameter has been changed and you return to the HOME screen without having first saved, the letter
E appears before the name to indicate that the preset has been modified but not saved.
18.2. FACTORY SETTINGS RECALL
It is possible to reset all the presets and all the global settings by returning the unit like just out of the factory. Turn the
unit off, press and hold the EDIT/ENTER button and simultaneously turn on the unit, do not release the button until the
operation is finished.
19. OTHER MIDI FUNCTIONS
The BURN is able to receive some MIDI System Exclusive messages in order to
directly control the parameters in real-time even if these are not assigned to
Continuous Controller numbers. The format of the SysEx string is as follows:
F0 08 45 1D xx yy F7
where xx = number of parameter and yy = value between 00 and 7F.
Parameter numbers are listed here.
0x00
Tube Gain
0x01
Tube Level
0x02
Parameter 1
0x03
Parameter 2
0x04
Parameter 3
In addition, you can send a string containing all the data related to a preset. The correct reception of a string preset by
the BURN overwrites the required preset number. The total length of the string must be of 70 bytes, of which the first 4
bytes are for the header, 1 byte is the number of preset, 64 bytes are the data of the preset, the last byte closes the
Sysex strings. The format is as follows:
PART NAME PART LENGTH CONTENTS
HEADER 4 bytes F0 08 45 1A
PRESET NUMBER 1 byte 00
PRESET NAME 12 bytes 49 6e 69 74 20 50 72 65 73 65 74 20
PARAMETERS 23 bytes 00 00 00 64 64 18 00 00 02 02 02 02 01 01 01 01 01 01 02 01 02 01 02
FOOTER 29 bytes 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00
END OF SYSEX 1 byte F7
The example given in the table above will overwrite the preset 0 with the default parameters. The 23 bytes for the
parameters correspond to the values of the parameters in the order in which they appear on the display. Values outside
the allowable range will be ignored.
