Eml synthesizers

OK I've had my EML for a few months now & love the wild & unpredictable sounds it can 
produce, but I'm still at square one with patching. Apart from the fact that patchbay is barely 
mentioned in the manual & is far from self-explanatory, when I try to patch things like EG1 
into the filter control I get...nothing!

Has anyone here some useful tips they could share? For example, is it possible to modulate 
the filter using both an LFO and an EG at the same time using a patch? Has anyone got a 
delayed vibrato patch?

All help gratefully received!
