Mike,

Here is one for you. Say you are in the key of C. Press the C key and the vibrato in Trumpet Soloist sounds like a good vibrato. Press the Db key and the vibrato sounds very slow. This is a good test. Now, press the Transpose button once to put you in the key of Db. Press the C key that sounded good in the key of C that is now a Db and it becomes the slow vibrato that was originally in Db in the key of C. One would think that the vibrato would be the same in the C key. I had assumed that whatever was assigned to each key in the keyboard remained the same regardless of changing the pitch of the key. The bad sounding vibrato follows right up the line with each transposition.
