I'm not super well versed in music prod. but I have recommendations? Sorta. I recommend you get the Akai MPK/MPC on Amazon, for budget. If you look that up on Amazon it'l come up with the real model name and it should be hovering around $99 USD last time I checked. To be transparent, I haven't personally tried but have heard its everything you need in terms of essentials/a solid first unit to start out with. So take all that with a grain of salt.
Secondly I recommend ableton as an all arounder for a DAW. Ableton seems like one of the standards that alike bedroom pop producers, big industry music also uses.
Thirdly, If you will be mixing said music, you'd rather have Reference headphones. These are headphones that allow you to hear things as close to the way you recorded them without altering it for aesthetic taste. These headphones will not color any of the music, leaving you exactly with what you recorded.
