I just upgraded my HS-60 and I'm finding that I prefer the OG Poly 1 and 2 functionalty. I would like to be able to play my synth as I would play a piano. Meaning, if I depress the sustain pedal, I should be able to play one key at a time and all notes will sustain until the sustain pedal is released. If I continue to play notes, the last note played will stop to allow for the new note to be played. This was the original functionality of Poly 1. Now, it seems I am unable to sustain multiple notes unless more than one key is pressed at a time. This is highly annoying. I also prefered the original functionality of poly II versus this new pseudo poly II. Is this something that can be restored? If not currently is this something that can be an option in a future firmware update?
