This is a common problem caused by the attempts of some manufacturers
to make their equipment more user friendly (while actually making
interfacing more confusing).
In the real world of MIDI data, program changes range from 0 to 127
in decimal numbers, (this is the same as 00 to 7F in hexadecimal or
0000000 to 1111111 in binary numbers). Most humans prefer to count
starting at 1 rather than 0, so these "helpful" manufacturers add 1
to the program numbers that the user sees in the interface. But not
all manufacturers do this, so there can often be a mismatch between
the user interfaces of two connected devices. If a controller is set
up to send the "correct" MIDI program change message, then it will
transmit program change "1" when you press the button that has been
programmed to send program change "1". However, one of the "helpfully
designed" controller devices will send out a program change of "0"
when you press the button that you think has been programmed to send
program change "1." This is OK as long as the receiving device has a
similarly deceptive user interface.
On the receiving en, devices that have been designed to display the
"correct" MIDI program change will always have memory banks number
starting at 0 and will load presets with the same number as the
actual program change number they are receiving. I assume you are
using the Behringer FCB1010. If you send out what "looks like" a
program change message of "11" and you are recalling program "10" on
the Line6 then this is due to Beringer being "helpful" in their
design will Line6 is being "correct" in theirs.
