in x1 I used this a bit. I had to press sustain pedal and the chord will remain unchanged until sustain is released. Hit new chord and press sustain again ad nauseum.
I had to get it set up in piano sustain mode I think and set a pedal on footswitches as austain -- but if you dont use set of foot pedals then a sustain pedal fitted to "sustain pedal" jack at rear of instrument does same function -- I suspect it will be similar in SD1 Pierce in Ireland
