I have an old Roland GP 8 effects process that I use to control the channels on my Tri-Axis. I've been using it this way for years. I was messing around tonight because I was programming other channels and trying to get the channel to match the preset. I don't know what I did, but I pressed something, Tri-Axis blinked the presets and programs went blank and came back on. Only thing is that my Roland no longer switches the Tri-Axis channels. No matter what I do, it won't work. I know I must be doing something wrong and am looking for any suggestions. Thanks.
