Hi list,
I'm new on patches programming, 
i've firstly done few things on presets patches, and layering to get 
the drum kit i wanted, but now i try to understand how all the 
programming stuff  works,

be sure i've read the manual :-D , i've understood little things on 
patchcords, but one: there are layers patchcords like 'dontno1' -
> 'dontno2' +00, which for me does mean that 'dontno1' dont make a 
thing on 'dontno2', but if remove this line, the sound change 
radiccaly in a way i can understand/figure,

hum, i wonder what this q and frequency values, because when i make 
changes, nothing seems to happen,

that's it,
if someone can help me..
