I've had a look at the mzx500 documentation and can't really understand if I could change registrations via midi or not. I'd be happy if there was another way to achieve the same thing, using songs instead of registrations, or using the mzx500 to set the stage setting on the pxs5. Basically I just want to be able to select the patch for a song on one of the boards and have everything set ready on both, so PX5s stage setting, mzx500 zones, pads, sliders etc - don't really mind which board I use as the 'master' to achieve this.
Cheers
Pete
