You can pretty much kiss 'plug and play' goodbye nowadays, Deane!

Most modern arrangers and WS's are so complex, and so non-standardized, getting two of them to work together is a major task for the best MIDI guru's out there.

Maybe 15-20 years ago, this would have worked for you, Deane (pretty much only the 127 Capitol Sounds, and a few common Variation sounds) but nowadays, all that is out of the window.

This is why I have talked about the need for module manufacturers to be FAR more flexible, and allow the sounds in them to be re-mapped to PC/32/00 codes that the sending gear is capable of sending. They never know WHAT is going to be hooked up to it, and it simply strikes me as foolish to hardwire yourself into one set of codes. All you are doing, essentially, is limiting the market you can sell to. Bad idea!

Particularly in a module that in all likelihood is going to be connected to an arranger, possibly the least flexible keyboard on the planet! Ketron would be wise to upgrade the OS to allow sound remapping...
