I am having a problem with the VH-11 Hi-Hat on my Roland TD-12 V-Drums kit. The edge trigger is not consistent. Often, the head sound will trigger instead while playing the edge. (Playing the head, that is, the bow, does consistently trigger the proper sound, however).
Apparently there is only one set of threshold/sensitivity settings for the VH-11 which affect edge and head/bow equally, so that will not help.
The problem is worse at lower playing velocities, where playing the edge will almost always trigger the head sound instead.
Any suggestions would be much appreciated.
