Lol, when I had my Mustang GT, I did have software for tuning it ;-)

Sometimes it's good to be able to change things, even though it takes a bit of trial and error. I modified a factory style and got it 90% to where I wanted. But the bass would still shift to a higher octave between Ab and G. So when I played a descending bassline for a song written in G major, the bass would go UP when i reached the I chord. It took a lot of experimenting, but I was eventually able to change the wrap point.

It would have been easier to use the master transpose, and send the notes through MIDI Out to an external sequencer, where they could be transposed back to the original key! Crazy!

As far as I'm concerned, it's important for users to be able to make changes such as this. Other brands include the ability to create and edit styles so there IS a demand for doing so. Roland should have made it easier and more flexible.
