This might be a good set of steps:
1) hook up both controllers at the same time
2) trigger the same thing with both of them
3) are the results different?
4) do you have other usb devices connected?
For debugging, if you are on Windows, you can load up MIDI-Ox and visually see the data come in from both devices. can you see a difference in timing?

Hey - guys, there seems to be some misunderstanding in this thread. It
now looks as Marcus are talking about audio latency - although his
first post gave the impression that he had problems with MIDI latency.
Marcus, maybe you can explain again so people with knowledge can give
accurate advice? ;-)'

I'm using a rolls midi buddy. It has never caused any sort of delay except
for now, when using USB.

Could the problem be your looper controller? What are you using?
It's surely not your MIDI interface. I remember having to return a
midi pedal once... I think it may have been a Yamaha, for this exact
reason. There was a noticeable delay between the time I stepped on
the button to the time it transmitted. Really silly. Control with my
FCB1010 is as close to instantaneous as it gets.
