I just bought a game port which connects to onboard MIDI (MPU-401)
on my PC motherboard. When this is connected, my synth goes crazy.
I'll play some notes and it will spontaneously transpose down a note
and then i hit some more notes and it switches to a different voice
altogether and pretty much goes crazy. i'm guessing it's because of
the MIDI connection.

I'm wondering if this is fixable and how to fix it? do i need to
get a different MIDI connection altogether? if so, what should i
get? how is the midisport (via USB) by m-audio?
