Has anyone done this? I did the 3X to the 1000 and saved the 1000 .SET and it was a royal pain. There has to be an easier way than spending countless hours matching up. Any comments, suggestions?

As with any different unit unless identical you MUST do your Homework...yes it takes time and many times you will find better, sounds, styles, fx, etc, when doing so, it's all part of the fun of setting up a keyboard for your needs. It never ends even after you think your finished until tested at full performance volume on stage a few times to correct the overall sound and parts etc, etc, thru your pa system ..that said did you buy the Pa4x, or? as you will have to do the same with the Pa4x also....its all part of the fun of being a musician..

I see...soften Jim up with some chat then hit him with the big question..you're showing your ulterior motive gene Donny :-)

No problem. Donny is always everyone's biggest fan. Helped me out numerous times and always will . I just don't know why he gave up on the 4X?

Zuki,.....I tried all the Korgs all fine instruments if you remember and two Pa4x's also,.....thru the years I found out that it's NOT the keyboard you use it's what you do with it, there is no magic about it, from arrangers, modules, synths, keyboards, etc,....I have been very successful using almost every arranger kb I've owned and that's been alot, brand loyal I'm not, finicky I am, ......but in the end I realized I can make good music with anything to back up my singing which is the main thing. Music changes, people change, needs change, technology changes, and I adapt accordingly always did for MY needs.
In fact I just borrowed a BIAB program from a friend to try out to see what it can do,....I really don't need anything but like to dip my toes here and there. I have always mixed it up & been flexible on stage and that's my formula for success. I wish you luck in your musical journey & if you need anything just hit me up buddy....

Take care
