Hi Ian
You’re still missing the point, so I will try a different direction.

We take a Yamaha 8 beat style from the S910, we then ask 10 S910 users to make it sound better than the original, (On their S910) after a short length of time each comes back with their personal version.
You now have 10 different 8 beat styles, so how do you define which one is better than the original? (Remember the factory styles are designed by Pro style makers)

The same applies to the MS.
Get 10 users of the MS, and the same Yamaha 8 beat style, then ask them to edit it to sound better than the original, and what you will get back are 10 different versions.
How do you define whether they are better or not?

Hopefully the above will emphasize the difficulty in conversion of styles, into a version that is better than the original. (It’s just subjective)

To look it another way, how do you define what is better, when even 10 users of the same closed keyboard can’t even agree.

Regards

Bill
