emusonacid! legacy

Hi,
I'm having a strange problem and i hope that someone can help me...

I'm controlling my E5000Ultra sampler through midi with another device. And i would like the emu to change presets when i change presets on the masterdevice, but it behaves rather strange, the emu doesnt follow the presets (programchanges) ...

when i change to

preset 1 > P080 (emu)
preset 2 > P048 (emu)
preset 3 > P336 (emu)
preset 4 > P080 (emu)
preset 5 > P004 (emu)
etc,etc

Anyone knows why this is this way?
I've checked that the master device has the right midimapping per preset.

Please help obiwan....
