I am looking at the FR-4X and the various sound sets. I have a FR-3S that is 11 years old and considering upgrading. The FR-4X comes with a ton of sound sets and each dealer seems to have their own customized user programs. Dale Mathis has a nice sounding set as does Faucetti. There is also an aftermarket user program set being marketed by Richard Noel and Gary Dahl. I am wondering if anyone has used all of them (or more than one) and which is the best organized for practical use. By that I mean if you were playing a "type" of music eg Italian, there would be a user program for it that would have the most useful tones and then if you switched to "Country" or Waltz or Polka, etc. there would be a user set that would group the most usable tones together. Hope this makes sense. I know its all subjective but before I plunk down $150 for user programs or try to write my own (maybe) I would like to hear the experience of others.
