What does the “BC:” and “VT:” mean in the VL70-m display?
The “BC:” and “VT:” in the upper left corner of the VL70-m are there as a convenience to indicate whether a patch is a breath controlled patch (a continuously controllable sound such as a horn or sax) or a velocity controlled patch (a percussive initially struck sound with no further control such as a guitar or other plucked sounds).
