Hi Nick , 

I've been through the programming manual , its of very limited help in reality . For such an incredibly deep (&expensive) unit , I dont understand why the knowledge base is so limited .

A seemingly simple thing like modulating the ISWITCH control select has me bewildered , after trying various sources , Im stuck , the only way I can do it is by assigning a knob and changing the select manually . I dont think that then looking through the 1000+ presets and trying to find a patch that implements the ISWITCH is practical . I've been studying the factory presets but every time I need to understand something new or have an idea , you're telling me the best way to go about this is go through the factory presets and study them…….!!! 

Do u guys offer email support for Vsig programming ?
