Thanks for all of the responses. I didn’t realize that the focusrite scarlett 2i4 almost acts like an amp. You don’t need a DAW to hear your guitar through your monitors which is different than most audio interfaces I’ve dealt with, so that threw my off a bit.
Regarding the drums and addictive drums - I actually ended up figuring it out after some thorough midi mapping attempts. I totally understand the logic now. If anyone needs any help with that let me know.
Also, thanks for the heads up on the reaper forums; I’ll be sure to go that direction next time.
