hey bud, welcome. I would also go with a MOTU or an M-Audio Fast Track Ultra, or Fast Track Pro. For monitors, I have KRK RP5’s… Amazing sound. Very good reviews, and on the lower end of the Monitor price range, by far. For midi keyboard, I have an Akai MPK49. Ever since I got my APC40, I dont use it much, but its great to get down ideas while diddling around. I play the piano too, so 49 keys helps me play with both hands, but if I had to do it again, I would get the APC40 and get those mini keys midi thingies. Just my $.02
Monitors are like DJ headphones, people can tell you which they prefer but as so many are pretty similar it really does come down to your own personal preference. Go to a store and ask to have a listen to a few, try them out and opt for the one you prefer the sound off (whilst one that will still get all the frequency ranges, ie: pref a 8inch bass)
After all it’s you that is working with them, you need to be happy and comfortable with what you’re working with.
There is no right or wrong, just opinion and preference.
