Im new to this forum so Hello everyone! I have a Ground Control Pro and a rig with Triaxis, Lexicon MPX G2, Mesa 50/50 and a MKIV head (dont have the FU-3) thru a Mesa 4X12 3/4 open back cab. If I was to use the MKIV separately, how can I switch the channels via midi if I dont have the Triaxis to do the external switching? I mean that with what device (that is available in Europe) can this be done? I know there are things like axess electronics gfx4 and stuff but I would have to order those. Thanks.
