The memory data of the Behringer FCB1010 MIDI Foot Controller (containing preset settings etc.) can be communicated via a SysEx (MIDI System Exclusive) message:
When the FCB1010 is in Global Configuration mode, pressing switch 6 ("SYSEX SEND") makes the FCB1010 send its memory data, and pressing switch 7 ("SYSEX RCV") makes the FCB1010 wait for the reception of a SysEx message containing memory data.

However, a SysEx message containing the FCB1010's memory data consists of 2352 bytes, which is uncommonly long.
Some MIDI interfaces cannot transfer this long SysEx message correctly because their internal buffer is too small.
Consequently, the SysEx message ends up at the other end maimed, and the SYSEX SEND/RCV operation fails.

Below are lists of MIDI interfaces reported to be capable or incapable of transferring the FCB1010's SysEx message correctly.
Note that for a MIDI interface to appear in the "compatible" list, it must work correctly both from the FCB1010 ("SYSEX SEND") and to the FCB1010 ("SYSEX RCV").
