In the band, Joseph covered a lot of the keyboard parts that Yanni could not for lack of hands in the shows. He assisted with the task of managing the 30 or more synthesizers onstage, and helped layer with the orchestra to create a "full-bodied, live-effect sound". He did have to adjust some parts that did not work well in a live situation and worked extensively on programming sounds for all keyboardists. Joseph said that "Yanni gave us musicians a great deal of freedom to expand the music as well. If you listen to the original recordings he did and what we ended up with in our live recordings, you can really hear the musician's input." He readily credits Yanni's role in his professional development, and for five years of irreplaceable experiences and memories.
