Hello Ray,
Sorry I haven't replied sooner, been very busy with 'gigs' lately, but slowing down now, so if you'd like to let me have your email address, I'll see what I can do.
Bye-the-way, I had a similar question about Custom styles put to me sometime ago and I still have a copy of my reply which I will send when I receive your address. Even if it isn't exactly the answer you're looking for, it may point you in the right direction.
Meanwhile, the quickest way to get back your original Custom Styles is to save everything to a card first, then initialise the keyboard which will put all the original styles, patterns, customs etc. back on to the keyboard just as it was when it left the factory. Of course, if you bought it second-hand, it may not be so easy as that, but I think it's worth trying as it could save you a lot of frustration.
