Hi Rikkisbears . Unfortunately we did not have enough time to examine the inticacies of style creation as that would be an entire DVD series all by itself . The current DVD series already includes a little bit on style creation but not the depth that i think you would benefit from. I cant help you with that one but we are in the process of establishing what things should be included on the 4th DVD. If you would like a section on style creation (and there are enough people who want this feature explained) we can hire another demonstrator to look specifically at this. I am prtetty sure that all the manufacturers use a similar format for NTT's and it may well be that this last DVD could have a section relating to the major common style editing functions. I do a bit of style creation myself but it is really trial and error for me.
Pop over to the Korgforum and add your request to the DVD thread . We will see what we can do.
