Eh... "Er20"? I don't know how many Marks there are in this forum, but
I did write something about "Er22"...

Anyway, I don't have a clear-cut answer to your problem, but here are
some thoughts:

First of all: I have never encountered any difference between USB and
standard MIDI for Reason-to-BCF/R communication, so I think you can
exclude Reason, or indeed your BCR: don't waste any more time flashing
firmware versions (just use 1.10).

You're probably on the right track that the problem is with your MIDI
interface. As I explained in the earlier post you're referring to,
Er22 can be caused by unwanted duplication of MIDI messages: this
completely ruins the BCR's reaction to a preset setup sent by e.g.
Reason. This happens because each SysEx message for the BCR contains a
message index, and the BCF/R expects a CORRECTLY indexed sequence of
messages, so a sequence of messages indexed "0, 1, 2, 3" etc. However,
when the BCR receives a sequence of indexes "0, 0, 1, 1, 2, 2", it
starts returning error message Er22 (and, crucially, doesn't update
its preset settings).

So my guess is that your MIDI interface indeed duplicates the messages
that Reason sends, via some feedback loop or whatever.

To confirm this, you might try connecting your MIDI interface's output
directly to a MIDI input on the computer, then send some data (from
any MIDI software program) to the MIDI interface's output, and  see
which data arrives back at the connected input (monitoring it by BC
Manager, MIDI-OX or whatever).

Mark.
