This is all very nasty: it seems a conspiracy of worst case scenarios...

The first error message ("MIDI system exclusive error - Wrong Model")
indicates that an Identity Request sent from BC Manager during
auto-detection has been answered with a System Exclusive message from
a Behringer model other than a BCF or BCR. I don't quite understand
how this can happen in your situation: I'm curious what the actual
offending received message. (The MOTU isn't Behringer-made, is it?)
In any case this error message shouldn't be fatal. (But anyway I'll
see if I can improve BC Manager's auto-detection algorithm, so that
you don't get this first error message.)

The second category of error messages is the really disturbing one. It
indicates that BC Manager's MIDI input buffer for "short" (i.e.
non-System Exclusive) messages is full. This buffer can contain 4096
messages, so what's apparently happening is that the MOTU sends a
continuous stream of "short" MIDI messages to the computer - maybe
"Autosensing" ($FE). In any case BC Manager itself does NOT send any
"short" MIDI messages during B-Control detection - only SysEx ("long")
 ones.

BC Manager regularly clears this MIDI input buffer, so this buffer
should never overflow. There are several reasons why this might go
wrong in your case:
- The FIRST ("Wrong Model") error message window might cause this
regular buffer clearing to be too slow - although I can't see how this
could happen. (Have you tried clicking away this first error message
IMMEDIATELY after it appears? Do you then STILL get the second category?)
- Your MOTU (or some feedback loop) causes a STRUCTURAL overflow of BC
Manager's short message buffer.

To establish what's causing this short MIDI message buffer overflow,
try the following procedure:

1. I've uploaded a special, "safe" version of BCMan.ini to the BC
Manager folder (under Applications) in the Yahoo group's file section:
"BCMan130Safe.ini". Copy this file to the folder on your harddisk
where BCMan.exe is located, and rename (or better: copy) it to
"BCMan.ini".

2. Switch off all BCs, and disconnect ALL your MIDI cables from your
computer/MOTU. Then start BCMan.exe: all MIDI I/O ports are now
disabled (cf. Options -> MIDI devices), and no auto-detection takes
place (cf. Options -> Detect B-Controls), so you should not get any
error message windows.

3. Open the MIDI input message window, either via the main window's
View -> MIDI input messages (general) or by clicking on the
red-striped button on the main window's toolbar. In the MIDI input
messages window, click on the Record button. (No messages should start
being recorded at this stage, since no MIDI input ports are enabled yet.)

4. Open the MIDI devices dialog box (via Options -> MIDI devices),
enable one of the relevant MIDI input ports, click OK, and watch the
"MIDI input messages" window: do any input messages start appearing
(and which ones)? Or do you get those "short message" error windows
again? As long as all remains well, you can enable the other relevant
MIDI input port(s), and after that your MIDI OUTPUT ports.

5. If you STILL have no problems at this point, you can connect and
power on your actual BCs. Then go to the B-Controls window, link each
BC 's MIDI I/O ports via the MIDI options window (MIDI -> Options),
and execute "Receive identity".

Let me know how far you get. Good luck!

Mark.
