Bc2000 (for the BCF2000 & BCR2000)

I've released a new version of MIDI Tools.
This includes a "MIDI System" window, which allows you to send nearly all types of MIDI System messages for testing purposes: Exclusive, Common and Real-time.
(Incidentally, this version also fixes a small but annoying bug in the MIDI Keyboard window.)
See http://home.kpn.nl/f2hmjvandenberg281/miditls.html .

So if you're still "on the case" of your BCN44's MIDI Merge, you can now have MIDI Tools generate Timing Clock and/or Active Sensing messages in conjunction with Note messages from the MIDI Keyboard window.
Maybe in this way you can determine whether it's indeed the Timing Clock and/or Active Sensing messages that mess up your BCN44's MIDI Merge - if you need any further confirmation.

Mark.
