FBV 'shortboard' (one expression pedal) on HD Pro.
I have used this shortboard live on the HD for years with no problem, expression pedal has always controlled volume (green LED) - unless you accidentally stomp it onto wah.
Recently in the studio I used the HD with a full FBV with 2 pedals and had no problem there either.
I went to use it live yesterday with the shortboard and each time you change patch, the pedal goes to 'WAH' (red LED) and the volume dies to zero.
I am suspecting that by plugging in a longboard FBV it has 'automatically' changed something in the HD which is not changing back when I plug in the shortboard.
Please does anyone know how to overcome this? Ideally I would like to be able to use both without having to mess around each time I change.
