E-Drum features not supported by BFD BFD’s samples are generally not recorded being struck indifferent positions (do not confuse this with hihat positions between open and closed, although some rides have bell and normal hit samples. Therefore, any positional control offered by your e-drums will not have any effect in BFD. For example, some Roland V-Drum systems send out positional information as MIDI continuous controllers. Please seethe section below entitled MIDI CCs’ for more details. Some e-drum kits offer 3 positions for ride cymbals. With these, you will need to map 2 of the positions to the same Hit type, as BFD’s rides are limited to hit and bell.
