In standard MIDI:
$90(=0x90) = "Note On" message on MIDI channel 1
$56 = Note Number 86 (decimal)
$7F = Velocity 127 (decimal)

So what you can do, is have a BCR button generate a Note On message.
E.g. via BC Manager's button dialog box under "Standard output":
Type = Note
Channel = 1
Note = 86
Velocity = 127
Mode = Toggle On

Then, when you press the button for the first time, it outputs $90 $56 $7F, and the second time it outputs $90 $56 $00.
(The second message is generated automatically under the BCR's protocol for Note messages for buttons. For more information see "BC MIDI Implementation.pdf", section 15.5.)

I suppose this is the note number again, so you'd have to use Note = 93 in this case.

Hope this helps,
Mark.
