The Tom assignments will vary on a kit by kit basIs…BFD Kits/expansions are not setup for e-drum kits…ie Tom 1/Tom 1 rim,Tom 2 /Tom 2 rim etc…Each Kit piece in BFD has a number of articulations with MIDI assignments…some have multiple MIDI note assignments…some Kits have high toms…high rack toms…mid toms and Floor toms.You may have a preset loaded with a different Tom configuration than what was mapped…2 high toms…2 floor…3 high toms…1 floor…2 high Toms…1 mid Tom…1 floor…2 high…2 mid…1 floor.etc etc
I mapped the according to the Roland keymap so everything is there , including the aux inputs which you may or may not be using.You can swap the MIDI Note assignments around easily and don’t even need the kit connected.Here is a post with a brief mapping guide.
Post the expansion you’re using and the preset and I’ll create a keymap just for that kit to help you get started.If it works well and all the kit pieces are correct I will update the link for the TD-17 map.
If you need a reference instead of using the Kit or having it hooked up , here’s the TD-17 Keymap…eventually you’ll have them memorized and won’t need to refer to it a number of the MIDI assignments are the same as GM Percussion Standard (General MIDI)
Also read through the E-Kit section…it gives you all the info you will need about additional mapping and dialing in the Hi Hat etc.

In the MIDI Key mapping section you can learn about the “Learn” feature and also about stacking,layering and Velocity Switching (Velocity Splitting)…which is switching articulations with MIDI Velocity…ie low velocity strike = Rim click…higher velocity = Rim shot etc
