Greetings,
I've been experimenting with MIDI control from one machine to another. I
checked the timing of a single note played simultanesouly by instances
of QSynth on both machines and was surprised to hear a very noticeable
flamming. I then replaced the MidiSport 2x2 with my Edirol UA25 and the
flamming disappeared. Both are USB interfaces, btw. MIDI routing between
the machines is handled by a Yamaha MJC8 and has never been problematic
with that box.
So, my question(s): Is the MidiSport just poorly designed and is there a
further condition or module option that can correct the timing delay
from that unit ?
Best,

Very interesting!
Are you sure that it is just delay? I've got disastrous jitter with my
Swissonic USB device. I would be happy if it's caused by the Swissonic
device. I couldn't check if MIDI would have no jitter when I use the MPU
of the Envy24 of my TerraTec EWX 24/96 sound card, all circuits I tried
on a BreadBoard failed and I also didn't test any other interface.
For me it's good news that one of your USB devices fails, while the
other is fine ;). It gives me hope that just the Swissonic USB device is
bad.
Cheers,
Ralf
