1. Have you tried disconnecting the effects pedal and double-checking that the midi is still out of tune.

2. Try opening the midi in Windows media player (or other audio program) and check that the pitch is still different.

3. What do you use to tune your guitar? Is the tuner set to A = 440 Hz?

Noel, just to answer the above questions. 1. I plug it directly to the JamMan xt solo and plug my headphones into phone jack of JamMan. No change. 2. Tried Windows media player and BB at same time, no change in pitch was detected. I use a Boss Guitar tuner to tune all my guitars and yes A is set to 440 Hz..

I tried turning up the semitones while song was playing but could not tell a difference in pitch. I will try opening in Real Band and see what tuning is like there. Thanks again for yur ideas and help.
