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
