I stand correct.....Walter, the topic you make reference is Secuence Registration, not the Real Time function I describe, this feature was available in the Yamaha Electones since the HS-HX, US1, AR AND EL series, it was called "shift registration" it did also had the secuence registration, so Yamaha has knowledge of this very handy feature when your hands are literaly "tie", this function is available in the arrangers Ketron MS, SD1s, X1, XD, etc....
The feature I would like to see in the next T2 O.S. update.
