I purchased a HD 147 and am using my older AX2 with it.Im using the long footboard i bought with the hd147. I connected the midi out from the HD147 to the AX2 midi in. My new footboard is changing channels on both amps and the volume pedal is working on both amps. The wah however only works on certain ax2 presets.When i used to use the AX2 alone with its footboard  the wah worked on just about all of the presets on the amp. Id like to get the maximum control off both amps with the new longboard. Is this possible and how do i do it?
