Dave Smith Instruments SYNTHESIZERS

hi,

if i request a program dump in combo mode  ex :F0 01 20 01 05 01 00 f7

all the voices get  the same program. i have to send a program change and it comes back to normal

the question is my polyevoler is HS or is it a firmeware PB?
if someone can send this sysex ( F0 01 20 01 05 01 00 f7 )  in combo mode and tell me if he has the same problem

thanks a lot
