In order to get my Redplate CD amp to switch channels by remote (using the HELIX as the controller) I bought a Voodoo Labs "Control Switcher" box. This box has a 5-pin Multi-out that can be programmed to send the corresponding signals to the amp's 5-pin port, using a somewhat re-configured midi cable. So far so good, using the front panel buttons on the box it sends out the right switching signals and the amp reacts accordingly. What it does not do however is react in any way to the MIDI PC/CC messages I try and send from the Helix , no midi signal reaches the Switcher.... duh. I've reset the Switcher, checked my midi cables, studied the manuals, to no avail. The good people at Voodoo Labs coulnd't find any fault in their product either, the tech-guys at Line 6 didn't get back to me yet so maybe someone HERE has had a similar problem and maybe found a solution...? Thanks !
