Reply to Traktor Pro S4 receiving wrong midi notes

Mac OSX 10.6.6, Traktor Pro S4

When I try to map any midi device (Traktor S4 in midi mode, Maschine in midi mode, my midi keyboard, etc), MIDI monitor/Logic show that the computer is receiving a midi note one octave lower than what Traktor receives.

So for example, if I map a button on my Maschine to send C2, MIDI monitor and things like Logic will receive C2 properly, but when I monitor the input with the "learn" function in Traktor, it always receives one octave higher at C3.

I've tested it with all my midi devices, and various software, and the Traktor software seems to be the only one doing it... it's driving me crazy.

Any ideas? Help greatly appreciated.
