Sysex dump problem

Sysex dump problem



Dear list!

If I request a sysex dump from my Ensoniq ESQM I often (not always) gets
problems with the last bytes of the dump. Maybe the last 1000 bytes or so.

Kurt Revis MIDI monitor always reports 8166 bytes from F0 to F7, and that
is correct. If I look at the bytes in the MIDI monitor every byte is
correct.

My app saves the dump to disc and when I look at it the last bytes of the
dumps is not correct. Often it's filled with zeros and garbage and the last
F7 is not there. But the number of bytes received (8166) seems to be
correct.

This happens only the very first time I request the dump from my
synthesizer after my app has started. I can request the dump again and
again and again after that and everything is always correct.

That leeds me to think that I have a problem with my MIDISport 4x4 or it's
driver. But I'm not sure. Can it be the MIDISPort USB data toggle problem?

How can the MIDI monitor be correct every time but not my app? I really
don't understand. Can someone please explain or give me a suggestion what
to do.

Best regards Peter
