If all the LED-s were off while this happened, you must have entered remote mode where the knobs become assignable to almost any MIDI message.
Regarding iPhone, doesn't it have an app that reads PDF files (such as the Virus manual)?
thanks for the response flabberbob.... Maybe this will help you too if you haven't read the manual either? It wasn't in Remote mode, thats fairly obvious as it tells you on the screen. The answer to the filter controlling the voc came to me as soon as i posted but haven't been able to get back online....
Basically the filter bank becomes/is disabled when the the voc is active so it makes sense the the filter bank controls voc params.... Im guessing now there is a similar mode for the arp being controlled from the amp env? Ill find out when i can get to the manual.
The i phone can read manuals your correct but needs to download them and im back at the computer now anyway.
cheers.
