The information I have is that the FBV Shortboard mkii will control some of the other spider 4 amps and Pods from line 6 but will it control the DL4 mkii? There are MIDI commands and technical information in the manuals but isn't that for an external controller (ie. midi keyboard of sequencer) to control your amp presets etc. How does my FBV S.B. mkii do the controlling of the presets of the DL4 mkii? Or will it?
