did you try MIDI controllers with another software?

What is this error message?

MIDI on XP is bad indeed, and I have to run my midi application under 
linux to get a latency lower than human sound perception, without 
artefacts, and with a cheap soundcard.

  If you know a bit about development you might be interested about this:

  Anyway, I suggest to have a deep look into your computer configuration,
you might have a problem with the system.

Indeed I use OSCx for a lower latency, but almost all paywares doesn't 
use this communication protocol. They are almost all stupidly stucked on 
the old MIDI.
