emusonacid! legacy

Hi,
apologies for the question not being in regards to an emu ultra sampler, however with this being pretty much the only decent EMU forum/fansite/whatever left, I was just wondering if anyone could help me out in getting my ESi-4000 to morph filter- I cannot seem to find the option for it anywhere. The operating software is version 3.02, if that helps in any way. Regards.
