Here's one big important improvement and I've tried it and it works perfectly now. I think it was Mario who needed this function fixed before he would consider any new Ketron product.
"Keyboard Harmony- The Harmony feature has been optimised such that notes (especially on percussive instruments) are no longer generated when keys played on the right hand side within a chord are released."
If you try this with acoustic piano for example, there is no longer the extra notes played when you release your fingers.
