Hi Florian (it's like talking to myself, just better),

Yeah, well... most of the time that one does its job, quite some 
programming work with a YS200 showed no issues (when relayed through the 
MOTU), also sending and receiving full dumps to/from an M1 worked out. 
Also I already have filled their pockets, as long as there is no 
pressing need, I won't fill the garbage can with it . Anyway, that's why 
I used the FCA1616 in parallel to test. And also the cheap cable uses 
class drivers, and the Behringer has its own, different drivers.

Usually / mainly something I have written myself using the WebMidiApi in 
Chrome. Also DX Manager 5 - I installed that to verify my suspicions, no 
experience with that, except that I successfully tested if it could talk 
to my TX7 - and also MIDI-Ox, SoundDiver and "MIDI Sysex file transfer 
utility". But except for the first, I'm no expert in any of these. I 
only know that with the cheap USB cable, I can't send bigger sysex with 
MIDI-Ox (that's why I installed the "MIDI Sysex file transfer utility").

I would usually believe that my own code would be the best source of 
truth for me, as I know what happens there. But then again, I don't know 
if the web midi api might already filter out stuff that it doesn't 
understand, and also of course I don't know if the Windows drivers might 
hide 'dirty' data.

I have not tried using Linux or a Mac yet - if there is a realistic 
chance that Windows is to blame, I'll give it shot.

Cheers, Florian
