Patches and discussion for Ensoniq VFX family

I've got the ver 4.1 ROMs from Syntaur, but they don't know (even no
one from the aktiv emu site) what is the difference between the old
2.3ver and the new 4.1ver. Can somebody help me in this?
Another question: Can the SD1's memory dissapear because the internal
battery voltage is low, but without any "Bathery Low" or "Check
Battery" on the display? 

Thank for everybody who still thrusts in this old staff profi keyboards.

I should like to buy an TS10 or something like it in Romania.
