I have just obtained an FBV Shortboard MKII for my Line 6 Spider II amp. I saw on youtube that the parameters can be changed (via an ios ap) so that the pedal for example can have 80% volume at rest and 100% on max. This is to enable a quick ramp up and return for solos. Does anyone if this can be achieved via the Line 6 FPV controller ap on my Windows 10 PC? If not does anyone know the name of the IoS AP and does this require an expensive cable to be used as I have heard? I have an iphone 6sPlus. Thanks in advance.
