Dave Smith Instruments SYNTHESIZERS

hi there,

recently got an POLY EVOLVER, love it, but it still has old OS
versions (Main 1.1., Voice 2.0 and DSP 3.0)

the oscialltors are bleeding in a strange way through the filters if
the cutoff is turned down the whole range. has this been fixed in
newer versions?

tried to update, but when it reads "OS load" on the evolver,
it does not count down. buffer settings on MIDI-OX are right.

any hints, any tipps?
