Since the routing in BFD seems to reset with each Preset, you would probably want to find the sound you want for the song you’re working on first and then route when you’re ready to record. The routing then would be saved in each DP project, or, you could potentially have BFD in your V-Rack routed the way you want and just swap drum pieces as needed and don’t use presets. I guess I just reroute for every song and have been doing it long enough that I don’t notice I’m doing it.
