Tascam Us 122 Midi Problems, Midi keeps changing keys on me... Options

[Gustuff]

I have been using the Tascam US-122 for a few years wth varying degrees of success. The analog interface with the phantom power and the guitar line inputs worked alright, although the level of the guitar input is a little low.... But the Midi keeps shifting keys on me. I assumed it was because I was using a powerbook G3, but when I upgraded my system to a ibook G5 with maxed out memory and 2 gig processor and I am still having problems with midi key variance. I have also switched to Logic from DP and still have the problems. Guess what... Tascam says they have never heard of this problem and suggest it is my midiman keyboard controller. Has anyone had a similar problem or think it makes sense that it is the keyboard?

Have you tried another MIDI interface?

If it does not do it with another one, it's maybe the M-audio which goes funky. Recalls me the noisy interface a friend had, it played random notes by itself…
