I do not really know how to articulate any better way than saying that I do not understand to configuration the settings for the Roland FD-8 Hi Hat pedal in conjunction with megadrum. I use an older Ddrum Hi Hat as the main Hi Hat ( I believe to have 3 sensors) with the FD8 as the foot control. Before switching units the two worked fine together. I use Superior Drum 3. I have the ARM 56 version. I downloaded the Manager FX and it will not link up, or change from red lights. Maybe this is a part of the problem?

Above are links to the two units. Maybe someone can give me some help?
