It is SOOOO Easy.....Right click in an empty area in the Track Control Pannel and choose Insert Virtual Instrument on New Track. Pick Toontrack DFH from the list. Now you will see a dialog box telling you that Reaper will build your tracks with routing automatically. Press okay and PRESTO..... Or go here and scroll down the list looking for EZD Track Templates. There are several. Regardless of your method it is handy that once you set up panning, volumes, fx and so forth on each track, then highlight the all the tracks, and choose save as template. Now the next time you want to add drums, you can right click and choose "Insert Tracks From Template" and all of your settings are ready to go, including drum maps, and kits.
