Buddy, it is not my intent to dissuade you from the T-3. If you really want a Tyros by all means go ahead and get one.
But, I hope you know that the internal styles from the KN5000 will work just fine in your KN7000. In fact, they were included in a group of files that were offered at a Tech Note web site that are already in KN7000 format. Not sure, but I think they are available at Bill Norrie's web site. If not, I've got them around here somewhere if you want them.
